The two major purposes of this study are: (1) To provide local school officials with information regarding the performance on basic skills achievement of each student who took the 1970-71 Michigan Educational Assessment Battery, and (2) To provide local officials with information that will assist them in understanding and interpreting their students' scores. The first of the four major sections describes the content of each sub-test (vocabulary, reading, mechanics of written English, and mathematics) in the educational assessment battery. The second describes cautions that must be exercised in the interpretation of individual pupil scores from the program. The third section explains how to interpret the materials that accompany this booklet, and the fourth defines statistical terms used in the educational assessment program and provides technical information regarding the educational assessment battery.
