A successful 3-year inservice training program for paraprofessionals, regular and early childhood educators was based on a modularized competency training model. Three modules were developed for each training group, with content including theoretical foundations, attitudes toward handicapped students, legislation, and planned observations of handicapped children in the classroom (module I); observation and recordkeeping, development of Individualized Education Programs, development of teaching strategies based on diagnostic profiles (module II); and behavior management, resources, team participation skills (module III). The program featured training activities as well as on-site visitations to program participants by the program coordinator. Participants were found to be more confident, made positive changes in their methods of discipline, improved in their ability to observe and informally diagnose, and increased their ability to design and implement educational programs for handicapped as well as normal students.
