This resource guide outlines procedures for efficiently and effectively planning and implementing transition programming for at-risk students. Based on a review and synthesis of needs assessment systems in transition programs, a flow chart is presented showing step-by-step procedures recommended for local transition needs assessments. Steps in the flow chart are numbered to correspond with numbered comments and instructions for implementation. The model presented in the flow chart is meant to be generic and flexible and is designed for use by those who want to complete a comprehensive systems needs assessment process as well as those who would like to enter the model at later steps. Three appendices, which make up the bulk of the resource guide, include: (1) an explanation of the California State Department of Education definition of transition and charts of the transition process; (2) a graphic representation of data collection methodologies; and (3) samples of 15 needs assessment instruments covering such program areas as client characteristics/demographic variables, standards for evaluating the quality of secondary special education programs, parent attitudes, community service program effectiveness, etc. (JDD)
