An overview of Ohio's proficiency testing program is presented and specific information pertaining to the testing at each grade level is detailed. The proficiency tests at each of four grade levels in Ohio include tests in writing, reading, mathematics, and citizenship, with science tests to be added in 1996. All of the tests, at grade level 4, 6, 9 and 12, are based on learning outcomes adopted by the State Board of Education. Every public school student must take all of the tests, which are administered by examiners who are certificated employees of the school district. The State Board of Education has established a proficient standard for each of the tests at each grade level. Tests are scored by a national scoring firm, and results are returned to the school district. Procedures are given for exceptions for disability, waivers, test security, and other testing policies. Descriptions of the tests at each grade level summarize the outcomes measured. An appendix presents an appeal form for oral administration of the ninth-grade proficiency tests. (SLD)
