The importance of conducting vocational follow-up studies increases as interest in employment-related education and training programs spreads. Expanding student enrollment and increased Federal and state support have prompted educators to develop models that determine the effectiveness of training programs. This monograph briefly introduces and outlines the basic elements contained in successful follow-up systems. It is organized in four sections. The first section provides general information about follow-up studies, while the second addresses the procedures and processes necessary to conduct former student follow-up studies. The third section examines the growing emphasis on and processes for conducting employer follow-up studies, and the last section covers the use of follow-up data. (KC)
