Characterizing the Special Education Goals of Autistic Students: Latent Class Analysis With Demographic and Developmental Covariates

Abstract

Many autistic children receive special education services via Individualized Education Programs (IEPs) that include specific educational goals and needs. Prior research has examined programming options available to support autistic students, but less is known about their educational needs across academic and developmental educational goals. Additionally, existing approaches have often relied on small studies focused on describing individual goal areas. This study uses data from 551 families from across the United States with an autistic child in grades K-12 and latent class analysis to (a) identify latent, or underlying, subgroups based off multivariate response patterns across educational goals endorsed in six domains (reading, writing, math, language and communication, social skills, behavior), and (b) examine if demographic and developmental covariates predict latent class membership. We identified five latent classes: All Goals (40.49%); Autistic Characteristics (21.63%); Language, Literacy, and Autistic Characteristics (18.99%); Academic (13.94%); and Language and Communication (4.95%). Two covariates—percentage of time spent in general education and adaptive behavior—predicted differences in latent class membership. Findings offer a comprehensive examination into the heterogeneous educational needs of autistic school-age children. Our results emphasize the need for researchers and educators to understand the educational needs of autistic students beyond the presence of an IEP.
