--- - |2 Abstract For individuals with intellectual disabilities (ID), transition services increase access to postschool opportunities. School psychologists should contribute to transition services but have reportedly limited involvement in this area. This study distributed a national survey (N = 176) assessing school psychologists’ current knowledge, attitudes, and behaviors regarding transition services for students with ID. Results indicated that attitudes toward and knowledge of the ID population were significant predictors of transition task performance, and knowledge was a significant predictor of transition‐related attitudes and behaviors. The results provided preliminary evidence that increasing school psychologists’ specific knowledge of transition services and encouraging positive attitudes toward the transition needs of students with ID may increase school psychologists’ performance in transition practice. Specific recommendations are provided. - Psychology in the Schools, EarlyView.
