The technical appendix to "The Career Intern Program: Preliminary Results of an Experiment in Career Education," Volume 1, reports on the research designs used for evaluating the Career Intern Program's (CIP) effectiveness in increasing the student's cognitive skills, academic achievement, vocational adjustment, future orientation, and self-image as compared to students who did not participate in CIP. Section 1 (156 pages) focuses on the experimental evaluation design and the following instruments used: (1) career development inventory, (2) self-esteem inventory, (3) internal-external scale, (4) CIP intern interview, (5) CIP parent interview, (6) CIP graduate intern questionnaire, and (7) employer questionnaire: graduate interns followup. Tabulated raw data, the basis for discussion in Volume I, are presented for the following areas: (1) intern characteristics when they enter CIP: frequency distributions of pretest measures; (2) gains made by interns over the first 10 weeks: pooled frequency distribution of pre- and post-tests for cohorts entering January and June 1974; and (3) differential gains made by subgroups of the January and June cohorts over the first 10 weeks. Section 2 presents the ethographic design used to collect qualitative data comprising the program description and case studies in Volume 1. Section 3 contains figures on cost per intern. (Author/EC)
