This report, the second in the 1975-76 series, is directed toward the local school district staff whose responsibility it is to read, interpret, and use the data generated by the Michigan Educational Assessment Program. This report combines in one booklet information that in previous years was contained in two booklets: the Individual Pupil Report: Explanatory Materials, and the School and District Report: Explanatory Materials. This booklet will be of particular value to the school principal and teachers. The 1975-76 Michigan Educational Assessment Program included objective-referenced tests in reading and mathematics at the fourth and seventh grades, a statewide pilot at the first grade, and a developmental pilot effort at the tenth grade with several volunteer schools. This report is devoted to an interpretation of the fourth and seventh grade data. In this report, the reader will find a discussion of the assessment measures, a detailed explanation of how to read each of the data reports generated by the program, and a set of suggested procedures for utilizing the test results. Some of this information can also be found on the principal's and teacher's test results folder provided to each participating school principal and teacher. (Author)
