Inclusion Impact on Students With ID

This cluster looks at what happens when kids with intellectual disabilities learn in regular classrooms instead of separate rooms. It shows small reading gains, no math boost, more stigma, and bigger behavior problems. Parents and teachers report these facts. A BCBA can use this to pick the best classroom spot and plan extra social and behavior help.

Key Findings

What 58 articles tell us

  1. An inclusive classroom placement was linked to better communication and daily living skills over three years for matched students with ASD in a French cohort study.
  2. IEP goals for students with extensive support needs are often compliance-focused and lack academic content or self-determination targets.
  3. Half of students with complex communication needs in one study received zero social-communication supports, regardless of placement setting.
  4. Students labeled with intellectual disabilities face increasing segregation over time, not less, with placement patterns tending to restrict rather than expand over the school years.
  5. Standard inclusive PE strategies can feel exclusionary to students with orthopedic needs, and asking each student directly what helps them feel included produces better outcomes.

Frequently Asked Questions

Common questions from BCBAs and RBTs

Research shows mixed results. Inclusive placements can improve communication and daily living skills, but they do not automatically provide the intensity of support complex learners need. The quality of the inclusion matters as much as the setting.

Research finds these goals are often compliance-focused, lack academic or self-determination content, and are written below the student's potential. Students with ambitious, skill-focused goals make more progress.

Advocate for goals with academic content and self-determination targets, ensure supplementary aids match actual student needs, and push for social-communication supports for students who need them.

Students with intellectual disability labels tend to experience more segregation, not less, as they move through school. Auditing placement patterns in your district can reveal whether this trend is happening and prompt earlier intervention.

Research shows that strong parent-teacher relationships and parent-perceived adequacy of accommodations predict better wellbeing and social inclusion for students with disabilities, independent of the formal supports listed in the IEP.
