The purposes of this study were to ascertain those practices and media that induced students to enroll in technician programs, to identify practices and media used by junior colleges to promote enrollment, and to determine the relationships between effective and ineffective practices and media. Data were collected from 79 junior colleges which composed a national sample selected on a proportional basis. These data included information gathered from the chief administrators and 757 first year students at these colleges. Findings were: (1) Counselors and teachers have a relatively high influence on these enrollment decisions, (2) Such decisions are generally made in grades 11 and 12, (3) Radio and television announcements are not used extensively nor are they a major influence, (4) Written media appears to have greater influence than picture media, (5) College catalogs and program descriptions are the most used and influential written media, (6) Student responses indicate college catalogs as the major influences twice as often as administrator responses indicated them as productive, (7) 3 percent of the students are influenced by advertising in college newspapers, and (8) Descriptions of employment and career opportunities are influential despite their source.
