Judge Rules in Favor of Releasing Teacher Test Scores; Data Dump Would Promote a Flawed and Cynical Method of AccountabilityBy Norm Scott
January 11, 2011 | Posted in IndyBlog | Email this article
Any effort to do so would spark a major outcry. But when it comes to teaching, there is a different standard.
The data dump will affect more than 12,000 classroom educators in Grades 4 to 8. The UFT is expected to appeal. There is some irony here as it was the UFT that signed off on the use of value-added in the first place after Joel Klein promised the results would not be made public, while many skeptical critics in the union raised questions about that deal and warned it would turn into a disaster for teachers and the union.
Ironically, it was only six months ago that the NY State Department of Education revealed that years of test score advances by city students had turned out to be a mirage causing Bloomberg and his former Chancellor Joel Klein a good deal of embarrassment. No matter – the Mayor is ready once again to wield unreliable test scores as a political weapon and most media in this city have deliberately short memories, having all too often been active partners in attempts to eviscerate teachers.
The value-added approach is the latest attempt to undermine teachers, the teaching profession and the teacher union by measuring teachers based on the performance of their students on standardized tests from year to year.
Crucial backing for such initiatives has come from private foundations led by billionaires like Bill Gates and Eli Broad who assert that data-driven models in the private sector can be transferred to public schools.
A study by Mathematica Policy Research done for the US Department of Education showed that one-fourth of average teachers will be mistakenly identified for special rewards while one-fourth of teachers who differ from average performance by three to four months of student learning will be overlooked.
A recent study by Sean Corcoran of NYU demonstrated that the New York City teacher data reports have an average margin of error of 34 to 61 percentage points out of 100. The National Academy of Sciences has also warned of the potentially damaging consequences of implementing these unfair and inherently unreliable evaluation systems. Even the NYC Department of Education’s own consultants have warned against using data for teacher evaluation.
Value-added measures can not only be in error but they provide incentives for teachers to manipulate scores by using large amounts of classroom time practicing for tests or engaging in various forms of cheating. To the extent a teacher cuts corners one year to deliver improved test scores, a student’s next teacher will face that much greater of a challenge to deliver similar or even better results.
Teachers under the gun of having their very lifelihood threatened will be very careful about working with troubled children who could drag down their value-added ratings. Accountable Talk” wrote about dealing with a request to take a class full of difficult students:
Still, it is wise to remember that not everything that counts can be measured and not everything that can be measured counts.

Here are some news story links I copied from Gotham:
- A judge said the city can release teachers’ value-added ratings. (GS, Times, Post, DN, NY1, WNYC, WSJ)
- The teachers union is planning to appeal the release, so it won’t happen yet. (GothamSchools)
- The Post says union president Michael Mulgrew is wrong to appeal the judge’s ruling.
