The Boston School Department has refused to release overall ratings of teacher performance at individual schools, denying families access to potentially powerful information that could shed new light on the quality of instruction.
The Globe had requested a breakdown of the teacher ratings for each school under a new job evaluation system that deems whether a teacher’s performance is exemplary, proficient, in need of improvement, or unsatisfactory.
The Globe only requested an aggregate of the teacher ratings at each school. Similarly, the Globe sought a breakdown of the ratings of more than 130 principals and headmasters as well as other administrators on a district-wide basis.
But on Thursday, school officials rejected the requests, saying that the ratings information is not subject to public disclosure.
