The 1977-78 Massachusetts statewide assessment of Career and Occupational Development (COD) included the development of test instruments, administration of the tests to a sample of thirteen- and seventeen-year-olds throughout the state, analysis and interpretation of the data, and dissemination of the results. The COD test was objective-referenced in nature. Each test item was matched to COD objectives in one of the following areas: job characteristics; job requirements; career decision making; basic skills; and attitudes and values. A panel of educators, school administrators, and business representatives met to evaluate the actual student performance in terms of their own "benchmark" of desirable achievement. Finally, the COD technical committee met to review all the results of the assessment and, with the input of the Benchmark Panel, generated a set of interpretative comments and recommendations for action. (This report describes the major outcomes of the assessment by reporting the following: performance on objectives; comparisons of the achievement of Massachusetts students with that of students within each age group; and highlights of the student and principal questionnaires. Also the interpretations and recommendations made by the panel and technical committee are presented. A companion document, CE 019 017, describes in detail the design and methodology of the assessment.) (BM)
