Abstract

This paper provides a comprehensive comparative analysis of inclusive education frameworks across New Zealand, Australia, Canada, India, and the United Kingdom, benchmarked against the United States’ Individuals with Disabilities Education Act (IDEA). Drawing exclusively from country‑specific policy documents and scholarly literature, the paper examines each nation’s legislative foundations, implementation structures, and conceptual approaches to disability. Each country section begins with its policy and legal framework, followed by a literature‑based analysis of implementation challenges, systemic inequities, and conceptual tensions. The United States’ IDEA is used as a comparative anchor due to its strong procedural safeguards and enforceable rights. The analysis reveals global patterns, including persistent gaps between policy aspirations and lived experiences, the influence of clinical or diagnosis‑driven models versus social‑interactionist models, and the central role of teacher capability. A comparative table summarizes key differences across the six systems. The paper concludes by identifying opportunities for strengthening inclusive education through systemic alignment, cultural change, and sustained investment.

Introduction

Inclusive education has become a central global priority over the past three decades, shaped by international human rights frameworks such as the United Nations Convention on the Rights of Persons with Disabilities (CRPD) and Sustainable Development Goal 4, both of which position inclusive, equitable, and quality education as a fundamental right. Countries across the world have responded by reforming legislation, restructuring educational systems, and adopting new conceptual models of disability. Yet, despite widespread policy commitments, the lived experiences of disabled learners continue to reveal persistent inequities, inconsistent implementation, and systemic barriers that limit meaningful participation.

This paper examines inclusive education across six countries: New Zealand, Australia, Canada, India, and the United Kingdom, using the United States’ Individuals with Disabilities Education Act (IDEA) as a comparative benchmark. These countries were selected because they represent diverse governance structures, socio‑political contexts, and conceptual approaches to disability, offering a rich basis for comparative analysis. Together, they illustrate how inclusive education is shaped not only by legislation but also by cultural beliefs, historical trajectories, funding models, and the capacity of educators and institutions.

The introduction of inclusive education in many countries has been influenced by a shift from medical and deficit-based models, which locate disability within the individual, to social and interactionist models, which understand disability as the product of environmental, structural, and attitudinal barriers. However, the degree to which these conceptual shifts have been embedded into policy and practice varies significantly. Some countries, such as New Zealand and Scotland, have embraced broad, rights‑based definitions of need, while others, such as England and parts of Canada, continue to rely heavily on diagnostic categorization and bureaucratic assessment processes. India’s framework is legally ambitious but constrained by systemic resource gaps, while Australia’s federal structure produces uneven implementation across states.

The United States’ IDEA provides a unique point of comparison because it is one of the most legally enforceable inclusive education frameworks in the world. IDEA mandates individualized planning, procedural safeguards, and the right to a Free Appropriate Public Education (FAPE) in the Least Restrictive Environment (LRE). While IDEA is not without challenges, its strong legal protections offer a valuable benchmark for evaluating the strengths and limitations of other national systems.

This paper adopts a structured comparative approach. Each country section begins with its policy and legislative foundations, followed by a literature‑based analysis of implementation challenges, systemic inequities, and conceptual tensions. The comparative analysis synthesizes cross‑national themes, including governance structures, definitions of disability, placement practices, teacher capability, data systems, and the persistence of segregated provision. The goal is not to rank countries but to illuminate how different systems conceptualize and operationalize inclusion, and to identify opportunities for strengthening inclusive education globally.

Ultimately, this paper argues that while legislative commitments are essential, meaningful inclusion requires systemic transformation, including cultural change, sustained investment, harmonized definitions, and robust teacher preparation. By examining diverse national approaches and benchmarking them against IDEA, this analysis contributes to a deeper understanding of what it takes to build educational systems where all learners can participate, belong, and thrive.

United States

The United States’ disability‑inclusive education system is grounded in the Individuals with Disabilities Education Act (IDEA), one of the most comprehensive and enforceable special education laws globally. IDEA guarantees that all eligible children with disabilities receive a Free Appropriate Public Education (FAPE) tailored to their individual needs and delivered at no cost to families (U.S. Department of Education, 2025). A core requirement of IDEA is the Least Restrictive Environment (LRE), which mandates that students be educated with nondisabled peers to the maximum extent appropriate, with removal from general education permitted only when supplementary aids and services cannot support success.

IDEA mandates that:

• All eligible students with disabilities receive FAPE tailored to their unique needs.
• Schools provide education in the LRE, meaning students must be educated with nondisabled peers to the maximum extent appropriate.
• Each qualified student, as not all students have an IEP, has an Individualized Education Program (IEP) developed collaboratively with families.
• Parents have extensive procedural safeguards, including rights to evaluation, due process hearings, mediation, and independent educational evaluations.
• States must ensure Child Find, early intervention, transition planning, and accountability for outcomes

IDEA is structured into major components, including Part C, which provides early intervention services for infants and toddlers, and Part B, which funds special education and related services for children ages 3–21. In the 2022–2023 school year, more than 7.6 million students received services under Part B, reflecting the scale of IDEA’s national reach (Congressional Research Service, 2024). The law’s central mechanism is the Individualized Education Program (IEP) a legally binding document outlining a student’s goals, services, accommodations, and participation in general education. The IEP must be developed collaboratively with families, reflecting IDEA’s strong emphasis on parental rights and procedural safeguards, including prior written notice, mediation, due process hearings, and independent educational evaluations.

IDEA also includes Child Find, which requires states to identify, locate, and evaluate all children with disabilities, including those who are homeless, migrant, or in foster care. Federal oversight is maintained through the Department of Education’s Differentiated Monitoring and Support (DMS) system, which evaluates state compliance and performance. In 2025, the Department issued updated guidance affirming that IDEA and the Elementary and Secondary Education Act (ESEA) fully support inclusive practices, emphasizing high expectations, access to the general curriculum, and participation in extracurricular activities (U.S. Department of Education, 2025). Additional protections come from Section 504 of the Rehabilitation Act and the Americans with Disabilities Act (ADA), which require reasonable accommodations for students who may not qualify under IDEA.

Despite its strengths, IDEA faces implementation challenges. Variation across states leads to inconsistent interpretation of LRE, shortages of trained special educators, and disparities in access to services. Disproportionality in identification and discipline also persists, particularly for students of color (Congressional Research Service, 2024). The system’s procedural complexity can create burdens for families and educators, who must navigate extensive documentation and compliance requirements. Even so, IDEA remains a global benchmark because of its enforceable rights, individualized planning, early intervention, and strong federal accountability mechanisms, features that many countries’ policies lack.​

New Zealand

New Zealand’s inclusive education system is grounded in a strong rights‑based legislative and strategic framework that has evolved over several decades. The Education Act 1989 first established the legal entitlement of disabled learners to enroll in their local state school, affirming that children with special educational needs have the same rights to enroll and receive education at state schools as people who do not (Education Act, 1989). This commitment was reinforced by the Human Rights Act 1993, which prohibited discrimination on the basis of disability in educational settings. New Zealand’s ratification of the UN Convention on the Rights of Persons with Disabilities (UNCRPD) in 2008 further embedded the social model of disability into national policy, recognizing that disability arises from the interaction between individuals and societal barriers (MacArthur, 2009; McMaster, 2012).

The New Zealand Disability Strategy 2026–2030 (NZDS) provides the most recent articulation of national direction, envisioning New Zealand as an equitable and accessible place for all disabled people and their whānau(families) where disabled people thrive, contribute, and choose the lives they want to lead (Whaikaha, 2025, p. 18). The Strategy identifies education as a priority area and commits to strengthening early childhood access, improving transitions, expanding specialist learning support, and ensuring timely provision of services. The NZDS builds on earlier reforms such as Success for All (2010–2014), the Learning Support Action Plan 2019–2025, and the establishment of Te Mahau (a national support structure designed to provide integrated, regionally responsive learning support). (Education Gazette, 2022).

Despite these advances, government documents acknowledge persistent inequities. Disabled children remain less likely to experience positive wellbeing and more likely to face barriers to participation and achievement (Education Gazette, 2022). The literature consistently documents a shift from medicalized, deficit‑based understandings of disability toward social and interactionist models emphasizing rights, participation, and systemic transformation (MacArthur, 2009; McMaster, 2012). MacArthur (2009) explains that early special education practices framed disabled students as deficient, while McMaster (2012) highlights the Strategy’s definition that disability occurs when one group of people creates barriers by designing a world only for their way of living.

However, translating inclusive aspirations into practice has been challenging. Selvaraj (2016) shows that exclusionary practices remain embedded in institutional structures, influenced by eugenics, developmental psychology, and deficit‑based categorization. Powell (2012) similarly notes that although the Education Act guaranteed enrolment rights, many schools resisted inclusion due to entrenched beliefs and inconsistent implementation. The Education Review Office found that only half of schools demonstrated mostly inclusive practice (McMaster, 2012).

School culture and leadership emerge as central determinants of success. McMaster (2012) argues that sustainable inclusion requires the transformation of underlying beliefs and assumptions, while Alesech and Nayar (2020) show that belonging is supported by attitudes, individualized approaches, teacher characteristics, effective teaching, and legal frameworks. Teacher beliefs and preparedness also shape practice: Clark-Howard (2019) found that teachers endorse inclusive values but feel underprepared and overwhelmed. Structural, cultural, and pedagogical barriers, including inconsistent access to learning support, deficit attitudes, overreliance on teacher aides, and assessment pressures, continue to impede meaningful inclusion (Selvaraj, 2016; Powell, 2012). Scholars argue that meaningful inclusion requires deep cultural change, sustained professional learning, and system-wide alignment.

Australia

Australia’s inclusive education system is grounded in a comprehensive rights‑based legal and policy framework. The Disability Discrimination Act 1992 (DDA) makes it unlawful for any school to discriminate against a student on the basis of disability in enrolment, participation, curriculum access, or support services (Australian Government, 1992). To operationalize the DDA, the Disability Standards for Education 2005 (DSE) require schools to ensure that students with disabilities can access and participate in education on the same basis as other students(Australian Government Department of Education, 2005). The Standards outline obligations in enrolment, participation, curriculum development, student support services, and protection from harassment, and they mandate consultation with families and documentation of reasonable adjustments.

The 2020 Review of the DSE found that although the Standards remain fit for purpose, implementation is inconsistent across states and sectors, with families reporting limited awareness of their rights and educators seeking clearer guidance on reasonable adjustments (Australian Government Department of Education, 2020). The Nationally Consistent Collection of Data on School Students with Disability (NCCD) further strengthens accountability by requiring schools to document adjustments and linking federal funding to these data. Teacher quality is regulated through the Australian Professional Standards for Teachers, which require competence in differentiating instruction and supporting students with disability (AITSL, 2014). The Australian Curriculum mandates access to age‑equivalent content for all students (ACARA, 2016).

Despite this strong national framework, implementation varies significantly across states due to Australia’s federal structure, resulting in a hybrid system where inclusive education coexists with segregated special schools and support classes (Beamish et al., 2022). The literature shows a clear shift from medical to social and interactionist models of disability. Dally et al. (2019) trace this evolution, noting that early special education conceptualized disability as an individual impairment requiring remediation, whereas contemporary approaches emphasize removing environmental barriers and modifying school practices.

Beamish et al. (2022) describe inclusive education as a reform still unfolding, shaped by state‑based governance and long‑standing patterns of segregation. Although 69% of students with disabilities aged 5–14 are educated in mainstream classrooms, the quality of inclusion remains inconsistent due to differing funding models, teacher preparation, and geographic constraints. Their review highlights persistent findings that pre‑service teachers feel underprepared and that inclusive pedagogies such as differentiated instruction and co‑teaching remain unevenly adopted.

Conceptual tensions are also evident. Forlin et al. (2015) argue that inclusive education lacks a unified definition, contributing to confusion in practice. Bourke et al. (2025) show that state policies often contain contradictory messages endorsing rights‑based inclusion while retaining language that supports segregation or conditional inclusion. Teacher capability emerges as the most critical factor across the literature. Dally et al. (2019) propose the Heads, Hearts, and Hands model, emphasizing that teachers require knowledge of legislation, commitment to inclusive values, and practical skills in differentiation and collaboration. However, evidence‑based practices remain inconsistently implemented, and more rigorous research is needed to evaluate their impact.

Overall, Australia’s inclusive education landscape is characterized by strong legal frameworks, evolving theoretical models, and persistent implementation challenges. Scholars argue that meaningful inclusion requires national coherence, sustained professional learning, and systemic commitment to removing structural, cultural, and pedagogical barriers (Beamish et al., 2022; Dally et al., 2019).

Canada

Canada’s disability‑inclusive education system is shaped by a dual-governance structure in which federal human‑rights commitments intersect with provincial authority over schooling, producing significant regional variation. Canada’s ratification of the UN Convention on the Rights of Persons with Disabilities (CRPD) in 2010 established a rights‑based foundation requiring that persons with disabilities not be excluded from the general education system and that they receive inclusive, quality, free primary and secondary education (Inclusion International, 2024; Inclusive Education Canada, n.d.). Article 24 mandates reasonable accommodation and individualized supports within general education. These commitments informed federal actions such as the unanimous adoption of Motion M‑78 in 2023, which reaffirmed Canada’s obligations and initiated a parliamentary study on disability‑inclusive education (Inclusion International, 2024). The Disability Inclusion Action Plan further emphasizes accessibility, equality, participation, and the principle of Nothing Without Us (Government of Canada, 2022).

Despite these commitments, civil‑society reports reveal persistent gaps between policy aspirations and lived realities. Inclusion Canada (n.d.) reports that fewer than half of children with intellectual disabilities are placed in fully inclusive classrooms, and these students are four times more likely than other disabled students to attend specialized schools. Thirty percent must leave their local schools to access education. Students with disabilities experience higher suspension rates, lower graduation rates, and elevated bullying, social isolation, and exclusion from extracurricular activities (Inclusion Canada, n.d.).

Provincial evidence, particularly from Ontario, reinforces these inequities. People for Education (2024) found daily shortages of educational assistants in 42% of elementary and 46% of secondary schools, with special education teachers frequently reassigned to cover general classrooms. As a result, 63% of elementary and 58% of secondary principals have asked parents to keep their child with special education needs at home (People for Education, 2024). Access to psychological assessments is also inequitable: 26% of elementary schools report regular access to psychologists, while 24% report none, disproportionately affecting low‑income communities (People for Education, 2024).

The literature provides deeper insight into the structural and historical roots of these inequities. Campbell (2021) situates contemporary disparities within Canada’s broader history, including the legacy of residential schools and the Truth and Reconciliation Commission’s findings of systemic abuse and long‑term educational disparities for Indigenous students. Although Canada performs well on international equity indicators, Indigenous students continue to experience lower achievement and reduced access to culturally responsive supports (Campbell, 2021).

Sokal and Katz (2015) argue that while Canada was an early global leader in disability rights, provincial autonomy has produced a patchwork of policies. Some provinces, such as New Brunswick, prohibit segregated classes, while others maintain parallel special‑education classrooms, withdrawal models, and categorical funding structures (Sokal & Katz, 2015). They emphasize that inclusion often focuses on academic placement rather than social belonging, leaving many students physically present but socially isolated.

Tremblay and Belley’s (2017) comparative analysis of Individualized Education Plans (IEPs) shows significant provincial variation, with no universal definition or template. They identify seven core IEP functions: communication, identification, planning, collaboration, adaptation, review, and transition, but note that these are unevenly implemented due to differences in teacher training and local capacity (Tremblay & Belley, 2017). Towle (2015) similarly finds that funding models often undermine inclusive practice by incentivizing diagnosis and reinforcing segregated service delivery.

Ontario’s policy framework illustrates these challenges. While the Special Education Policy and Resource Guide emphasizes early identification, UDL, and differentiated instruction (Ontario Ministry of Education, 2017), Alyass and Buist (2025) argue that Ontario’s system continues to reflect historical segregation. Placement pathways from regular class with indirect support to full-time special education classes create stratified outcomes that disproportionately affect disabled, racialized, and marginalized students (Alyass & Buist, 2025). Teacher education programs provide limited training in disability, inclusive pedagogy, or anti‑ableist practice.

Empirical evidence from Community Living Ontario’s Crisis in the Classroom report (2025) reveals widespread exclusionary practices: 29% of students experienced seclusion (often in locked rooms), nearly half were secluded more than ten times, 14% experienced physical restraint, 21% attended school on modified or part‑time schedules, and 31% were sent home because schools could not meet their needs (Community Living Ontario, 2025). These findings indicate systemic issues across provinces.

Overall, Canada’s inclusive education landscape is defined by strong rights‑based commitments but persistent structural inequities, provincial fragmentation, and inconsistent implementation. Scholars argue that meaningful inclusion requires harmonized definitions, stronger data systems, increased investment, and coordinated policy reform (Sokal & Katz, 2015; Towle, 2015).

India

India’s disability‑inclusive education framework is grounded in a comprehensive rights‑based legal architecture shaped by the Rights of Persons with Disabilities Act, 2016 (RPwD Act), the Right of Children to Free and Compulsory Education Act, 2009 (RTE Act), and the National Education Policy (NEP) 2020. Together, these policies articulate a national commitment to ensuring that children with disabilities receive equitable access to education, reasonable accommodation, and individualized support within mainstream schools. The RPwD Act mandates inclusive education and requires governments to provide reasonable accommodation and individualized support to enable children with disabilities to learn alongside peers (Department of Empowerment of Persons with Disabilities, n.d.). The RTE Act positions children with disabilities within the category of disadvantaged groups, requiring neighborhood schools to admit them and prohibiting discrimination (Ministry of Education, n.d.). NEP 2020 reinforces these commitments by emphasizing universal access, barrier‑free infrastructure, specialized teacher training, assistive technologies, and multidisciplinary support services (Ministry of Education, 2020). Government schemes under Samagra Shiksha operationalize these commitments through provisions such as home‑based education, resource rooms, assistive devices, and teacher training (Ministry of Education, n.d.).

Despite this strong legal foundation, the literature consistently shows that India faces major systemic gaps that hinder the realization of inclusive education. Sharma and Vinayan (2024) argue that although India’s framework aligns with SDG‑4, the needs of children with disabilities remain inadequately met. They highlight severely underreported disability data due to outdated definitions, inconsistent terminology across major acts and schemes, and weak coordination between ministries. India has 14.89 lakh schools, yet only 18 lakh of the estimated 80 lakh children with disabilities are enrolled, indicating that a majority remain outside the formal education system (Sharma & Vinayan, 2024). Early childhood access is especially limited: only 10.1% of children with disabilities have ever attended preschool, and nearly three‑fourths of children under five remain out of school (Sharma & Vinayan, 2024). These gaps reflect deep structural inequities that begin early and compound over time.

Saiyam et al. (2024) emphasize that although the RPwD Act recognizes 21 categories of disability, translation into practice remains uneven, particularly in rural and underserved regions. They identify inadequate assistive technologies, shortages of trained special educators, limited access to multidisciplinary assessments, and societal stigma as major barriers. At the same time, they highlight emerging opportunities such as improved policy enforcement, expanded teacher‑training programs, multisensory teaching, individualized learning plans, and school–community partnerships (Saiyam et al., 2024). These opportunities suggest that India’s inclusive education system is evolving, but requires sustained investment and systemic coordination.

Historical and cultural factors also shape India’s inclusive education landscape. Roshan and David (2025) trace India’s shift from a charity‑based to a rights‑based approach, showing how disability has historically been influenced by caste, religious beliefs, and social stigma. Although post‑independence laws such as the 1995 Persons with Disabilities Act and the National Trust Act (1999) marked progress, implementation continues to be hindered by entrenched attitudes, misunderstandings, and inadequate infrastructure (Roshan & David, 2025). These historical legacies contribute to persistent exclusion and reinforce the need for culturally responsive approaches to inclusion.

Anjana and Abhilash (2024) report that less than 20% of children with special needs consistently access schooling despite strong legal commitments. Government schemes such as IEDC, PIED, SSA, IEDSS, RMSA, and IECYD have expanded opportunities but face persistent barriers, including inadequate infrastructure, shortages of trained educators, and uneven execution across states (Anjana & Abhilash, 2024). Disability Studies in higher education remains underdeveloped, limiting research capacity and the availability of trained professionals.

State‑level variation further complicates implementation. Lalmuankimi and Shree (2023) demonstrate that the implementation of the RPwD Act is highly uneven across states, with many schools lacking trained special educators, accessible infrastructure, and adequate assistive devices. This variation reflects broader disparities in state capacity, funding, and political commitment.

Overall, India’s inclusive education landscape is characterized by strong legal commitments but persistent systemic gaps in data, resources, teacher preparation, infrastructure, and societal attitudes. Scholars argue that meaningful inclusion requires harmonized definitions, stronger data systems, increased investment, and coordinated efforts across government and communities (Sharma & Vinayan, 2024; Saiyam et al., 2024). Without addressing these structural and cultural barriers, India’s ambitious legal framework risks remaining aspirational rather than transformative.

United Kingdom

Inclusive education in the United Kingdom is shaped by a complex and evolving policy landscape influenced by national legislation, devolved governance, and international human rights commitments. Although education is devolved across England, Scotland, Wales, and Northern Ireland, the UK is unified by statutory duties such as the Equality Act 2010, which prohibits disability discrimination and requires reasonable adjustments across all educational settings (Equality Act, 2010). The UK is also bound by the UN Convention on the Rights of Persons with Disabilities (CRPD) and its mandate for the progressive realization of inclusive education. Historically, the Warnock Report (1978) and the Education Act 1981 established the modern concept of special educational needs (SEN) and the presumption of mainstream placement (Lauchlan & Greig, 2015).

Despite these shared foundations, the UK does not operate a unified inclusive education system. Each nation interprets inclusion differently. England’s SEND framework, shaped by the Children and Families Act 2014 and the SEND Code of Practice (2015), remains heavily influenced by medicalized categorization and bureaucratic assessment processes (Department for Education, 2015). The emphasis on identifying significantly greater difficulty in learning reinforces diagnostic labeling and contributes to rising numbers of Education, Health and Care Plans (EHCPs) (Squires, 2025). Scholars argue that this system incentivizes families to pursue diagnoses rather than addressing structural barriers within mainstream settings (Squires, 2025).

In contrast, Scotland’s Additional Support for Learning (ASL) framework, grounded in the Education (Additional Support for Learning) (Scotland) Act 2004, adopts a broader, environmental definition of need. Additional Support Needs (ASN) may arise for any reason, including social, emotional, linguistic, or situational factors (Scottish Government, 2017). Although widely regarded as progressive, implementation remains uneven due to resource constraints and variable local authority practices (Knight et al., 2023).

Wales’s Additional Learning Needs (ALN) reforms, introduced through the ALN and Education Tribunal (Wales) Act 2018, aim to create a unified, rights‑based system with a single statutory plan for all learners requiring additional support. However, scholars note that while the reforms emphasize early intervention and person‑centered planning, they provide limited guidance on transforming pedagogy or curriculum (Knight et al., 2023).

Northern Ireland continues to operate a more traditional SEN framework shaped by its selective and historically segregated school system. The SEN Code of Practice (1998) and its 2005 supplement emphasize staged assessment and reasonable adjustments, but academic selection at age eleven and the dual system of controlled and maintained schools create structural barriers to inclusion (Department of Education Northern Ireland, 1998, 2005). Policy language also includes caveats such as allowing less favorable treatment with justification, weakening inclusion commitments (Knight et al., 2023).

The literature consistently highlights a gap between policy aspirations and lived experiences. Lauchlan and Greig (2015) identify conceptual tensions between universalists advocating full inclusion and moderates supporting specialist settings. They show that inclusion is often interpreted narrowly as physical placement, rather than meaningful academic, social, and emotional participation. Knight et al. (2023) argue that UK policy documents contain contradictory messages, simultaneously endorsing inclusion while reinforcing deficit‑based frameworks. Squires (2025) provides a compelling critique, showing dramatic increases in EHCPs, special school placements, exclusions, suspensions, and children missing education. He argues that these trends reflect systemic failures rather than increased incidence of disability, driven by rigid curricula, high‑stakes accountability, and insufficient teacher support.

Across the literature, teacher capability emerges as a central determinant of successful inclusion. Scholars argue that meaningful inclusion requires moving beyond individualized, compensatory approaches toward preventative, whole‑school strategies that address structural inequities, redesign learning environments, and invest in teacher capability (Booth & Ainscow, 2011; Knight et al., 2023).

Comparative Analysis Across Six Countries

A cross‑country comparison reveals both shared commitments and significant divergences in how inclusive education is conceptualized, legislated, and implemented.

Legal Foundations and Rights:

All six countries recognize inclusive education as a right, influenced by the CRPD(Convention on the Rights of Persons with Disabilities). However, the strength of enforceability varies. The United States’ IDEA provides the most robust procedural safeguards, while countries like India and Canada rely more on policy commitments without equivalent legal enforcement mechanisms (Schuelka, 2018; Inclusion International, 2024).

Governance Structures:

Federal or devolved governance shapes implementation. Australia and Canada exhibit significant regional variation due to state/provincial control (Beamish et al., 2022; Sokal & Katz, 2015). The UK’s four nations operate distinct systems (Knight et al., 2023). In contrast, IDEA provides a unified national framework across the U.S. (Schuelka, 2018).

Conceptual Models of Disability:

New Zealand, Scotland, and Australia increasingly adopt social or interactionist models (MacArthur, 2009; Dally et al., 2019). England, India, and parts of Canada retain more medicalised or deficit‑based frameworks (Knight et al., 2023; Sharma & Vinayan, 2024). IDEA blends both, using categorical eligibility but emphasizing individualized supports (Schuelka, 2018).

Placement vs. Participation:

Across countries, inclusion is often interpreted as placement rather than meaningful participation. Scholars in New Zealand, Australia, Canada, and the UK highlight that students may be physically present but socially or academically excluded (McMaster, 2012; Beamish et al., 2022; Sokal & Katz, 2015; Knight et al., 2023). IDEA’s LRE requirement similarly focuses on placement, though participation quality varies (Schuelka, 2018).

Teacher Capability:

Teacher preparation emerges as the most consistent barrier across all countries. Pre‑service teachers often feel underprepared, and ongoing professional development is inconsistent (Clark‑Howard, 2019; Beamish et al., 2022; Alyass & Buist, 2025; Saiyam et al., 2024; Lauchlan & Greig, 2015).

Structural Barriers:

Common barriers include inadequate funding, shortages of specialists, inconsistent access to assessments, and societal attitudes. India faces the most severe resource gaps (Sharma & Vinayan, 2024). Canada and the UK struggle with systemic fragmentation (Sokal & Katz, 2015; Knight et al., 2023). New Zealand and Australia face cultural and structural inconsistencies despite strong policy frameworks (Selvaraj, 2016; Beamish et al., 2022).

Data and Accountability:

The U.S. and Australia have the strongest data systems (IDEA reporting; NCCD) (Australian Government Department of Education, 2020). India and Canada face significant data gaps (Sharma & Vinayan, 2024; People for Education, 2024). The UK’s data systems vary across nations (Knight et al., 2023).

Segregation vs. Inclusion:

Special schools remain prevalent in Australia, Canada, India, and the UK (Beamish et al., 2022; Sokal & Katz, 2015; Anjana & Abhilash, 2024; Squires, 2025). New Zealand has reduced but not eliminated segregated provision (Powell, 2012). The U.S. maintains a continuum of placements but emphasizes LRE (Schuelka, 2018).

Overall, while all countries articulate strong commitments to inclusion, implementation gaps persist globally, driven by structural inequities, conceptual tensions, and insufficient teacher preparation.

Discussion

A cross‑national analysis of inclusive education in New Zealand, Australia, Canada, India, the United Kingdom, and the United States reveals a global landscape characterized by strong rhetorical commitments to inclusion but persistent gaps between policy and practice. Although each country has adopted legislation aligned with the CRPD and Sustainable Development Goal 4, the degree of enforceability, conceptual clarity, and systemic coherence varies widely. A central theme across all countries is the tension between rights‑based aspirations and implementation realities. New Zealand and Australia articulate strong social‑interactionist frameworks, yet both continue to struggle with structural barriers, inconsistent access to learning support, and entrenched deficit‑based attitudes (MacArthur, 2009; Beamish et al., 2022). Canada’s federal–provincial divide produces significant regional variation, with some provinces advancing progressive models while others maintain segregated structures (Sokal & Katz, 2015; People for Education, 2024). India’s legal commitments are ambitious, but systemic gaps in data, infrastructure, teacher preparation, and societal attitudes severely limit implementation (Sharma & Vinayan, 2024; Saiyam et al., 2024). The United Kingdom’s devolved systems produce divergent approaches, with Scotland adopting a broad environmental definition of need while England retains a more medicalized, bureaucratic model (Knight et al., 2023; Squires, 2025). The United States’ IDEA stands out for its strong procedural safeguards, but it too faces challenges in equitable implementation and overreliance on categorical eligibility (U.S. Department of Education, 2025).

Across all countries, teacher capability emerges as the most consistent determinant of meaningful inclusion. Scholars in every context highlight that teachers often feel underprepared, overwhelmed, or unsupported in implementing inclusive pedagogies (Clark‑Howard, 2019; Dally et al., 2019; Alyass & Buist, 2025; Lauchlan & Greig, 2015). This pattern suggests that legal frameworks alone cannot transform educational systems without sustained investment in professional learning, collaborative practice, and school‑wide cultural change. Another cross‑cutting theme is the persistence of segregated provision, even in countries with strong inclusive rhetoric. Special schools, withdrawal models, and diagnostic‑driven funding structures remain common in Australia, Canada, India, and the UK (Beamish et al., 2022; Sokal & Katz, 2015; Anjana & Abhilash, 2024; Squires, 2025). New Zealand has reduced but not eliminated segregated options (Powell, 2012), while the U.S. maintains a continuum of placements under IDEA (U.S. Department of Education, 2025).

Data and accountability systems also vary significantly. The U.S. and Australia maintain robust national data systems (U.S. Department of Education, 2025; Australian Government Department of Education, 2020), while India and Canada face substantial data gaps that hinder planning and monitoring (Sharma & Vinayan, 2024; People for Education, 2024). The UK’s data systems differ across nations, contributing to conceptual and operational fragmentation (Knight et al., 2023). Overall, the comparative analysis demonstrates that inclusive education is not a singular model but a complex interplay of legal frameworks, governance structures, cultural beliefs, and resource allocation. While IDEA provides a strong benchmark for enforceable rights, no country has fully realized the transformative vision of inclusion articulated in the CRPD. Achieving meaningful inclusion requires systemic alignment, cultural change, and sustained investment across all levels of the education system.​

Conclusion

This comparative analysis highlights that while New Zealand, Australia, Canada, India, the United Kingdom, and the United States all articulate strong commitments to inclusive education, their approaches differ significantly in conceptualization, implementation, and enforceability. Countries with strong rights‑based frameworks, such as New Zealand and Australia, continue to face cultural and structural barriers that limit consistent practice (MacArthur, 2009; Beamish et al., 2022). Canada’s provincial variation and historical inequities create uneven access to supports (Sokal & Katz, 2015; People for Education, 2024). India’s ambitious legal commitments are undermined by systemic gaps in data, infrastructure, and teacher preparation (Sharma & Vinayan, 2024; Saiyam et al., 2024). The United Kingdom’s devolved systems produce divergent models, with England’s medicalized framework contrasting with Scotland’s broader environmental approach (Knight et al., 2023; Squires, 2025). The United States’ IDEA remains the most legally enforceable system, but its procedural complexity and inconsistent implementation highlight ongoing challenges (U.S. Department of Education, 2025).

Across all countries, the literature underscores that meaningful inclusion requires more than policy reform. It demands a shift from individualized, compensatory approaches toward preventative, whole‑school strategies that address structural inequities, redesign learning environments, and invest in teacher capability (Booth & Ainscow, 2011; Lauchlan & Greig, 2015). Without such systemic transformation, inclusive education risks remaining an aspirational ideal rather than an educational reality. This paper demonstrates that global progress toward inclusive education is uneven but evolving. By examining diverse national approaches and benchmarking them against IDEA, policymakers and educators can identify opportunities for strengthening inclusive systems through harmonized definitions, improved data systems, sustained professional learning, and culturally responsive practices. Ultimately, achieving equitable, high‑quality education for all learners requires a collective commitment to dismantling barriers and building educational environments where every child can participate, belong, and thrive.
