This fourth report in the 1973-74 series presents a compilation of the scores of Michigan's fourth and seventh grade students who participated in the educational assessment. Results of the objective-referenced test data reveal that while none of the objectives was attained by all of the students, performance levels were quite high for some of the objectives. A table summarizes the test results in the form of a distribution chart. This chart shows the number and percentage of objectives attained within each of the ten intervals of pupils. Levels of attainment were generally higher in mathematics than in reading. Another table lists the objectives attained by more than 80 percent of the pupils while the next table lists the objectives attained by fewer than 20 percent of the pupils. The report of results for all grade four and seven objectives in both reading and mathematics is included. Guidelines for the data interpretation indicate some of the possible ways errors can be introduced into test results. (RC)
