Inclusive education has been a cornerstone of educational policy in the UK, with a strong push toward integrating students with disabilities, including those with Down syndrome (DS), into mainstream classrooms. The Individuals with Disabilities Education Act (IDEA) and similar frameworks emphasise inclusion, highlighting the benefits of learning alongside non-disabled peers. Research, such as the study by Buckley et al. (2006), demonstrates that some students with DS in mainstream settings achieve significant gains in expressive language, literacy, and behaviour compared to those in special education.
However, while mainstream education can work well for some, it is not universally suitable for all students with DS. Many face challenges that lead to a high rate of transition out of mainstream schools before secondary education, as evidenced by a large-scale UK survey showing only 37% of students with DS remain in mainstream secondary schools compared to 80% in primary schools. This article explores why mainstream schools may not meet the needs of many students with DS, drawing on research and practical considerations, while acknowledging that inclusion can succeed for some with adequate support.

Challenges in Mainstream Education for Students with Down Syndrome
Variability in Support and Teacher Preparedness:
Mainstream schools often lack the specialised training and resources needed to effectively support students with DS. A 2021 study by Hargreaves et al. found that only 59.51% of parents with children in mainstream primary schools felt that staff had access to relevant training, and 87.85% believed schools would benefit from more. Teachers frequently report limited knowledge of DS-specific needs, relying on background reading or minimal in-service training, often provided by organisations like the Down Syndrome Association rather than formal education systems. This gap in training can hinder teachers’ ability to adapt curricula or employ effective teaching strategies, such as step-by-step instruction or concrete concept emphasis, which are critical for students with DS. Without adequate support, students may struggle to access the curriculum fully, leading to frustration and disengagement.
Social and Behavioural Challenges:
While mainstream settings can foster social inclusion, they do not always guarantee meaningful social integration. Buckley et al. (2002) noted that students with DS in mainstream schools showed no significant differences in social contacts outside of school compared to those in special education, suggesting that friendships with non-disabled peers may not extend beyond the classroom. Moreover, students with DS often face challenges in social communication due to delays in expressive language, which can be exacerbated in mainstream environments where peer interactions are fast-paced and complex. The 1999 Hampshire survey highlighted that students in special schools scored higher on interpersonal relationships, with older teenagers more likely to have a boyfriend or girlfriend and participate in clubs, possibly due to a more tailored social environment. For some students, the social demands of mainstream settings can lead to isolation or behavioural difficulties, prompting a move to special education.
Academic Demands and Curriculum Access:
Mainstream classrooms are designed for typically developing students, with curricula that may not be sufficiently differentiated for those with significant learning disabilities. Students with DS often have cognitive and language delays, with expressive language lagging more than two years behind receptive language in special education settings, and literacy skills significantly behind those of mainstreamed peers. While mainstream schools can enhance literacy and language outcomes through exposure to a richer linguistic environment, as noted by Buckley et al. (2006), this benefit is contingent on effective differentiation and support. Without these, students may struggle to keep pace with academic expectations, particularly as they progress to secondary school, where the curriculum becomes more complex. The drop from 80% of students with DS in mainstream primary schools to 37% in secondary schools reflects the increasing difficulty of meeting these academic demands.
Transition to Secondary School:
The transition from primary to secondary school is a critical juncture where many students with DS leave mainstream education. The 2020 survey by Fox et al. reported that while 65% of students with DS attend mainstream schools overall, this figure drops sharply at the secondary level. Secondary schools often have larger class sizes, more subject-specific teachers, and less individualised attention, which can overwhelm students with DS who require consistent support. The lack of national-level guidance and training for inclusion, as highlighted in a Down Syndrome Education International article, exacerbates this issue. Successful mainstream placement depends heavily on local education authorities and school staff attitudes, leading to inconsistent experiences. For many families, the challenges of navigating this transition prompt a shift to special schools, which offer more tailored support and a curriculum better aligned with their child’s needs.
When Mainstream Education Works
Despite these challenges, mainstream education can be highly effective for some students with DS when the right conditions are met. Buckley et al. (2006) found that students in mainstream classrooms made significant gains in expressive language (over two years) and literacy (over three years), equivalent to four and six years of progress for typically developing children due to the slower developmental pace of students with DS. These gains are attributed to exposure to typically developing peers, who provide role models for language and behaviour, and higher academic expectations in mainstream settings. Inclusive education also fosters social acceptance and can prepare students for community integration. However, success requires robust support systems, including trained staff, additional classroom assistance, and individualised education plans (IEPs) or (EHCPs) that address specific needs. Schools with committed leadership, optimistic staff attitudes, and systematic monitoring, as outlined by Ainscow and Muncey (1988), are more likely to facilitate positive outcomes.
Why Many Students Leave Mainstream Before Secondary School
The high attrition rate from mainstream to special education before secondary school reflects systemic and individual challenges. The variability in school resources and teacher training creates inconsistent experiences, leaving some students without the support needed to thrive. Socially, the lack of sustained peer friendships outside school can diminish the inclusive benefits of mainstreaming. Academically, the increasing complexity of the secondary curriculum often outpaces the ability of schools to provide adequate differentiation, particularly in under-resourced settings. Parental concerns, as noted by Hargreaves et al. (2021), about insufficient training and support further drive decisions to transition to special schools, where environments are more controlled and tailored to developmental needs. Additionally, health considerations, such as those highlighted by the Down’s Syndrome Association, can influence placement decisions, as special schools may better accommodate medical needs alongside educational ones.
Recommendations for Improving Inclusion
To make mainstream education more viable for students with DS, several steps are necessary:
- Enhanced Teacher Training: Schools should implement mandatory, ongoing training on DS-specific needs, focusing on differentiation and inclusive teaching strategies.
- Increased Support Staff: Additional classroom assistants, as seen in some Dutch models, can provide the individualised support students with DS require.
- Social Inclusion Programs: Schools should foster peer relationships through structured activities and community involvement to extend social benefits beyond the classroom.
- National Guidelines: A standardised framework for inclusion, akin to the National Literacy Strategy, could ensure consistent support across schools, reducing variability in outcomes.
Conclusion
Mainstream education offers significant benefits for some students with Down syndrome, particularly in language and literacy development, when supported by trained staff and robust systems. However, the challenges of inadequate training, social integration difficulties, and increasing academic demands lead many students to leave mainstream schools before secondary education in the UK. The sharp decline from 80% in primary to 37% in secondary schools underscores these barriers. While inclusion aligns with ideals of equality and social acceptance, special education may better meet the needs of students requiring more tailored support. A balanced approach, prioritising individualised support and systemic improvements, is essential to ensure that mainstream education is a viable option for more students with DS.
