Ohio Graduation Test

Sophomores at more than 400 high schools across

Ohio are being given for the first time starting today what may be the most important exam they've ever taken: the Ohio Graduation Test.

It's a five-tests-in-five-days marathon. For the two parts of the exams for which the grading scale has been established, reading and math, students can get more than half of the questions wrong and still reach the "proficient" level and thus pass the exam. This year's sophomores must pass all five portions of the test to graduate with a diploma. And the test is designed to be tough. State education officials say the test is about two grade levels more rigorous than what it replaces, the Ninth Grade Proficiency Test. That's in part because the test includes more short-essay questions and problems that make students show their work and explain their answers rather than just filling in a bubble.
