The effects of a teacher consultation intervention were examined--namely, the collaborative model for promoting competence and success (COMPASS), which was designed to improve objectives of individualized education programs for children with autism. The intervention consists of an initial parent-teacher consultation, followed by four teacher consultations across the school year. Thirty-five teachers and a randomly selected child with autism (M age = 6.1 years) from each classroom participated. Compared to the nonintervention teacher-child dyads, the intervention teacher-child dyads showed improvements in individualized education program objectives, with a large effect size ( d = 1.51).
