An introduction reviews literature on the assumptions underlying mainstreaming and research on the academic and social effects of mainstreaming for handicapped children. Methodology is the topic of another section which outlines the assessment instruments used, including self report measures, the Peer Rating Scale, student folder data, participant observer questionnaires, a parent questionnaire, and a retrospective questionnaire.
