Parents and teachers provide complimentary information in the assessment of preschoolers so it is important to understand parent–teacher agreement, especially for children with autism. Parents and teachers rated an ethnically diverse sample of preschoolers with autism (N = 257; 67% Latino) on the Devereux Early Childhood Assessment (LeBuffe and Naglieri in Devereux Early Childhood Assessment: User’s guide, Kaplan Press, Lewisville, 1999). Correlations between parent and teacher ratings were moderate and significant for social skills (r = 0.20–0.37) but near zero for behavioral concerns. Parents rated children as having stronger social skills and fewer behavioral concerns than teachers, unlike prior research with typically developing preschoolers. Both informants rated White/other children more positively than minority children on several subscales, although agreement was similar across groups. Implications for practice are discussed.
