The rationale for using multiple evaluation strategies in a comprehensive program evaluation is described. Examples are given of eleven strategies used in the evaluation of the Experience-Based Career Education project developed by the Northwest Regional Educational Laboratory through sponsorship of the National Institute of Education. Strengths and limitations are cited for the use of pre- and posttesting in an experimental design, student followup and longitudinal studies, student case studies, content analysis, adversary hearing, cost study, ethnographic study, use of local study committee, organizational study, panel review by experts, and survey questionnaires. Six criteria, proposed for consideration in determining the best evaluation strategies to use, are discussed. These are cost, timing, credibility of findings, degree of obtrusiveness, amount of coordination needed, and efficiency. (Author/RC)
