This paper is a behavioral analysis of learning and behavior problems which may be expected of severely developmental^ disabled persons in vocational settings. The behavioral analysis includes three major sections: (1) a categorization and description o primary problems encountered by a severely handicapped population, (2) a logically arranged hierarchy of behavioral procedures which can be used to treat different types o problems, and (3) a general set of management strategies. It is recommended that the hierarchy of behavioral procedures be empirically validated.
