This publication is concerned with two major questions: What does the paraprofessional do? and How should a paraprofessional be trained? The duties of the paraprofessional are described as clerical, monitorial, and reinforcing of instruction, and these tasks may be either non-interacting (performed with things rather than persons), or interacting (performed directly with children or other adults). Examples of each category are given. The taxonomy is designed for use in training programs with a behavioral orientation. Examples of task sheets are given for each category and are intended only as samples, with trainer teams urged to adapt them to suit their own needs. Non-interacting tasks and interacting tasks are included, and each category in both groups is represented. There are four steps in each task sheet: 1) The specific task is stated behaviorally. 2) The needed skills, knowledge, and understanding are stated. 3) Training designs, methods, and materials for developing the needed skills, knowledge, and understanding are listed. 4) The plan for evaluation is stated.
