This paper, meant to stimulate discussion within the employment and training community, offers a wide range of strategies for keeping clients enrolled in Job Training Partnership Act (JTPA) programs. Issues discussed include the following: (1) why retention is important; (2) gathering and analyzing information; (3) links between client recruitment and retention; (4) retention through intake; (5) technologies for increasing retention after enrollment; (6) improving on-the-job retention; and (7) retaining employers through good times and bad. The handbook stresses throughout that client retention is not an issue that begins after job placement; by then it is often too late. Retention begins with program planning and design, continues through recruitment, intake, program participation, and job placement. The handbook points out some places to start. (KC)
