This manual for supervisors in the Summer Youth Employment Program (SYEP) provides background on SYEP and tips on program supervision. Section 1 is a brief introduction. The history and purpose of SYEP are presented in section 2. Section 3 contains nine SYEP supervisor work rules (concerning time records, safety, accidents and illness, termination, problems, youth's grievances, political activity restriction, records and reports, and youth rules) and lists six SYEP objectives. In section 4 youth attitudes toward work and the effect of work experience programs on youth are discussed. Section 5, which outlines the job of the SYEP supervisor, lists fifteen supervisor tasks and contains five subsections on program supervision. The first subsection outlines sixteen steps for preparing to supervise. The second and third subsection provide guidelines for orienting and training youth. A five-step instructional plan is explained in subsection 4, and a seven-step system for evaluating participant's performance is presented in subsection 5. Subsection 6 contains a brief discussion of SYEP worksite evaluation. Supervisor's reference forms are included in the final section. (Manuals for training supervisors in SYEP, youth in SYEP, and establishing SYEP worksites are available separately through ERIC--see note.) (MN)
