This explanatory booklet and the materials that accompany it have two major purposes. The first purpose is to provide local school officials information regarding the performance on basic skills achievement of each student who took the 1972-73 Michigan Educational Assessment Battery. The second purpose is to provide local officials with information that will assist them in understanding and interpreting their students' scores. This booklet has four major sections. The first section describes the content of each test--word relationships, reading, mechanics of written English, and mathematics--in the educational assessment battery. The second section describes cautions that must be exercised in the interpretation of individual pupil scores from the program. The third section describes the materials that accompany this booklet and explains the pupil scores that they contain. The fourth section defines statistical terms used in the educational assessment program and provides technical information about the educational assessment battery. (Author)
