Yesterday in court, the United Federation of Teachers argued that the DOE should not release the teacher data reports to the public, despite FOIL requests from media outlets, because the value-added methodology on which they are based are statistically unreliable, among other reasons, a point also made by many researchers, including Sean Corcoran of NYU. (See articles about the court case in today's Gotham Schools, NY1, Daily News, NY Times, and Post)
In February 2009, almost two years ago, I submitted a FOIL request to DOE for a number of items related to these reports, including the supposed "panel of technical experts" who had approved the DOE's methodology, according to the statement in the 2008 document, “Teacher Data Initiative: Support for Schools; Frequently Asked Questions":
Juan Gonzalez of the Daily News wrote about this here; I wrote about it and provided back up documentation here.
“Teachers’ Value-Added scores from the model are positively correlated with both School Progress Report scores and principals’ perceptions of teachers’ effectiveness, as measured by a research study conducted during the pilot of this initiative.”
In February 2009, I also asked for a copy this "research study." Coincidentally,I just received yet another email from DOE today, informing me that this study is still not complete, more than two years after the above claim was made, and nearly two years since I filed my original FOIL. (see letter above).
