Eyebrows raised over city school policy that sets 50% as minimum score

"Pittsburgh Public Schools officials say they want to give struggling children a chance, but the district is raising eyebrows with a policy that sets 50 percent as the minimum score a student can receive for assignments, tests and other work.

The district and teachers union last week issued a joint memo to ensure staff members' compliance with the policy, which was already on the books but enforced only at some schools. Pittsburgh Federation of Teachers President John Tarka said the policy is several years old."
