The 1973-74 Michigan Educational Assessment Program (MEAP) provided information on twenty-two separate measures of interest to educators. The program provides for measures of (1) word relationships, (2) mathematics, (3) reading and (4) attitudes (optional). In contrast to past programs, the mathematics and reading instruments are objective-referenced. Each test contains items that measure a set of minimal performance objectives. Committees of Michigan educators assisted in the development and review of both the objectives and the items. Because of the representativeness of the content domain, the tests, in general, can be judged to have good content validity. However, there are individual cases of unclear objectives or test items which need to be improved. The reading and mathematics test in their entirety are reliable tests for group decision-making. However, for certain objectives, the measured reliability of the five associated test items is such that caution should be used before making decisions about an individual's attainment of a particular objective. A majority of the objectives were mastered by between 50 and 90 percent of the students. In general, students who scored higher on the word relationships test did better on the objective-referenced tests. Last, the attitude surveys utilized in the assessment program appear to be reliable measures of two separate factors. (Author/RC)
