The manual is intended to provide guidelines to Washington local education agencies (LEAs) and Head Start programs on interagency agreements. Factors involved in agreements are discussed, and an example of a proposal for service coordination touches on aspects of recruitment and outreach, screening, team staffing, assessment/diagnosis, individualized educational program planning, delivery of services, and tracking. A discussion of elements of agreements (such as program delineation and roles and responsibilities) is followed by information on Washington state procedures for developing contractual agreements between Head Start agencies and LEAs. The document concludes with a sample interagency agreement. (CL)
