The city doesn't want to come off looking like the bad guys. They need the UFT to support them in releasing this data. So sometime between now and the court date in November, look for the DOE and the UFT to come to some sort of new "agreement". It will probably entail releasing the data some time down the road, perhaps in 2011 when the new evaluations are set to take place. The UFT will agree to release the TDR data as part of some "teacher report card" that includes the TDRs, plus evaluation data, etc. The UFT will claim that this system is fairer because it will give a "big picture" view of a teacher's performance rather than just the narrow TDR view.
By doing this, the UFT can continue to look like a friend of reform while still claiming to be protecting teachers. They'll be able to claim victory even as the reports come out.
Don't think this can happen? Think back to the many things the UFT has signed on to and claimed as a 'victory'. The 2005 contract. Loss of seniority. Changes in tenure evaluations. Race to the Top. The added 37.5 minutes in each school day. ALL of those were claimed as wins for the UFT while they were losses for the members.
Don't say I didn't warn you. TDRs, and along with them your privacy, are the next great compromise.
