Metropolitan Achievement Tests (MAT) and Otis-Lennon Mental Ability Tests were administered to elementary school students of the Oklahoma City Public Schools. Results of the testing are presented in tables and consist of: elementary school test results as compared to the national means in reading, language, and mathematics; a comparison of scores attained by elementary school students in 1972-73 and 1973-74; middle school test results in reading, language, and mathematics; and the percentages of students scoring in each grade level of the MAT in reading and mathematics, respectively. The test results in individual elementary and middle schools are profiled in the appendices. For each school the following kinds of information are presented: subtest grade equivalent score means, distances of the grade score means from the national norms, the mid-percentile ranks of the grade score means (another norm-referenced score), and the stanines associated with the mid-percentile ranks. Results are presented for purposes of comparison, but the evaluator must realize that test scores are highly dependent on socioeconomic background, home environment, heredity, and geographic locale.
