Beginning in February 1994, twelfth-grade students who have passed the Ohio Ninth-grade Proficiency Tests in all areas will take the Twelfth-grade Proficiency Tests in writing, reading, mathematics, and citizenship. This fact sheet describes the Twelfth-grade Proficiency Test in mathematics, which is designed to measure a twelfth-grade level of mathematics literacy as defined by 19 learning outcomes developed by Ohio educators and adopted by the Board of Education in 1988. This fact sheet describes the mathematics test, which consists of 50 multiple-choice questions, divided among the 5 categories (strands) of arithmetic, measurement, data analysis, algebra and functions, and geometry. Each question has four answers. Students are permitted, but not required, to use a calculator in taking this test, although it is designed to be calculator neutral. The three types of questions students will encounter are those relating to knowledge and skills, conceptual understanding, and application and problem solving. Most students will be able to complete the test in 75 minutes; 2.5 hours are allowed. (SLD)
