Columbus, Ohio (AP) -- A teacher's legal bid to get copies of the standardized tests for Cincinnati Public School freshmen has flunked.
The Ohio Supreme Court ruled 5-2 Thursday that the exams are protected trade secrets, exempt from state public records law.
High school teacher Paul Perrea began in 2007 seeking copies of tests evaluating ninth-graders at the end of each semester.
He said he wanted to have the exams evaluated for fairness, accuracy and validity.
Justice Judith Ann Lanzinger wrote for the majority that Cincinnati Public Schools spent more than $750,000 developing semester exams and has gone to great lengths to guard their secrecy.
Teachers aren't allow to make copies.
The court says making them open records would allow student access, leaving them with little value in evaluating student progress.
