To assist school administrators and guidance personnel in providing job placement services, a study was conducted to: (1) develop a model design for a school-based job placement system, (2) identify students to be served by the model, (3) list specific services provided to students, and (4) develop job descriptions for each individual responsible for operating the system. Forming the developmental basis for the school-based job placement model are these components: (1) the overall educational system, (2) job openings developed cooperatively by the educational system and the Bureau of Employment Security, (3) cooperation between the educational system and the Bureau of Employment Security in matching students with employment opportunities, (4) follow-up of students, and (5) feedback of information to provide input for program improvement. The model is specifically concerned with that part of a differentiated guidance staff charged with the responsibility of working cooperatively with the Bureau of Employment Security in job development and job placement. This handbook describes the procedures followed in developing the model, implementation strategies, securing information about student's characteristics and job requirements, developing a computerized career planning and job matching system, and evaluating a job placement service system.
