The workbook is designed to assist Oregon counties in developing comprehensive written plans for early intervention with students with disabilities. The process is broken down into seven stages with information on necessary actions at each stage: (1) forming an early intervention advisory group (conducting initial planning meetings); (2) setting a county goal (developing a goal statement); (3) determining needs of target populations (completing early intervention plan components worksheets); (4) identifying community resources; (5) developing an accurate data base (using the information retrieval form); (6) developing objectives for plan components; and (7) compiling the comprehensive plan for early intervention services. Sample forms and worksheets are provided throughout. Appendices include a copy of House Bill 2021 mandating early intervention services for all handicapped children in Oregon and a copy of the Oregon administrative rules for early intervention services.
