Information about education in Oklahoma beginning with the 1989-90 school year and continuing through December of 1990 is presented in a concise and usable format. This document is an overview of information useful to the public. Sections include: (1) common education recognitions and achievements; (2) 1990 school legislation; (3) educational evaluation, including results from nationally standardized tests; and (4) statistical information about the school system. Several students, administrators, and programs from the Oklahoma schools have gained recognition for achievements. Many educational reform efforts were the focus of legislation in 1990, ranging from finance to assessment. Key indicators of the U.S. Department of Education indicated that in 1988 Oklahoma ranked 32nd in high school graduation, 44th in current expenditures per pupil, and 28th in percentage of federal funds. In 1989, the state ranked 24th (out of 28) in scores in the American College Testing Program. In 1990, the state adopted the Iowa Tests of Basic Skills and the Tests of Achievement and Proficiency as measures of student achievement. Scores ranged from the 53rd through the 59th percentiles. Data relating to these and other indicators of education in Oklahoma are presented in 15 tables and 22 figures. Four appendices describe: (1) 1990 legislation; (2) benefits and cautions concerning the use of standardized tests; (3) the Oklahoma Graduation Test Program; and (4) student and professional staff minority representation.
