Who Are the Classmates of Students With Disabilities in Elementary Mathematics Classrooms

The Individuals with Disabilities Education Act stresses the importance of educating students with disabilities (SWDs) in the least restrictive environment, often with peers who do not have disabilities. Prior research has examined the extent to which SWDs are included in general education classrooms, but not the characteristics of the peers with whom SWDs are educated. We examined the math classmates of fourth- and fifth-grade SWDs from one state. On average, SWDs were grouped with twice as many other SWDs, about four per class, than students without disabilities. Students with learning disabilities had fewer peers with disabilities in their classrooms than students with other disabilities. Students with intellectual disabilities, autism, or emotional/behavioral disorders more often had peers with disabilities, often their same disability. Our results provide directions for future research regarding peer effects and understanding how schools group SWDs.
