“Significant Flaws” with New York’s Teacher Evaluation Data


New York “State officials admit problems with new teacher ratings” is how the headline reads. More specifically, it seems that New York State Education Department officials are acknowledging “significant flaws” with their new system of rating more than 126,000 teachers statewide by their effectiveness, and these errors are causing the state to push back the public release of these data.
While the state did not disclose any details to help define with what types of “significant flaws” the state was dealing, anecdotal evidence suggests there may be rating errors across similar tests and scoring errors whereby teachers who score consistently across subject areas are scoring below par in their overall categorization/ranking.
