This guide for establishing and evaluating Summer Youth Employment Program (SYEP) worksites consists of seven sections. Section 1--the introduction--describes the history and scope of the SYEP and discusses the need for worksite development. Section 2, which deals with identifying community needs, lists eight information-gathering approaches. Section 3 describes organizing information about these community needs. Needs areas discussed are health and mental health, housing, environmental protection, education and child development, the aged and homebound, transportation, public works, community organization, income maintainance, recreation, culture and arts, equal opportunity, consumer protection, public safety, and economic development. Section 4 contains a checklist for identifying effective worksite agencies. Section 5 outlines four steps for developing work experience projects and contains observations on orienting potential worksite employers. These observations involve youth needs, staff, transition, and assistance. Section 6 describes worksite agreements. Monitoring and evaluating worksites is the subject of section 7; thirteen questions useful in site evaluation are included. (Manual for youth in SYEP, for SYEP supervisors, and for training supervisors in SYEP are available separately through ERIC--see note.) (MN)
