A handbook to assist states in fulfilling requirements of Public Law 94-142 to provide a Comprehensive System of Personnel Development (CSPD) for special education staff is presented. The handbook is intended to help writers develop, review, update, and implement the CSPD, which is one section of the state plan submitted to the federal government. The workpages of the handbook are divided into eight sections, each of which contains the appropriate regulation, suggestions for writing the section, possible resources, and corresponding items from the "OSE Reviewer's Guide," on which the evaluation of the state's plan is based. The eight sections of the plan cover the following: the introduction, groups participating in the development and revision of the CSPD; the annual assessment for determining personnel training needs; the inservice and preservice plans; efforts to disseminate and promote adoption of information and practices in personnel development; the CSPD evaluation; and technical assistance offered by the state education agency (SEA). Appended materials include the "OSE Reviewer's Guide," sample data tables and instructions, a list of primary CSPD persons in SEAs, a list of groups who may participate in CSPD development, several sample needs assessment and inservice questionnaires, examples of inservice training plans, information on college special education programs, and a list of agencies providing technical assistance.
