This is the final report of a project initiated in September 1965 to: (1) determine and measure the environmental factors and the social-psychological characteristics of students which are related to the success or failure of occupational programs; and (2) to identify a variety of typical educational career patterns and to isolate teams of predictor variables (environmental, community, personal, and socioeconomic) by which educational career patterns may be significantly differentiated. A battery of tests, inventories and rating scales was administered to 10,857 students in 24 colleges; 9,610 students (89 percent) submitted complete and scorable records. The student data profile was generated through administration of the Junior College Student Inventory and a 15-scale inventory of preferred conditions and rewards of work (Work Values Inventory). Data on environmental influences was gained from a set of four Junior College Environment Scales, a pair of Faculty Preference Scales, and a series of 13 Community Characteristics Indices. A variety of statistical treatments was applied to study variable interactions and their relationships to student program choice, educational career patterns, program completion, and postcollege employment status. Results are described and pertinent literature is reviewed. Sections of the survey instruments are appended. (Author/DC)
