This ruling makes sense. For those of you who don't understand this, read the NYTimes article "When The Numbers Lie" by Michael Winerip. It follows a very dedicated and excellent teacher's journey with her class. Not only did the principal admire her, but so did the parents and staff. Yet, do to a mere less of a tenth percentage point under the evaluation system called VAM, the city deemed her ineffective. Editors and some people from their comments here don't understand how these tests are evaluated under a system called VAM. Studies have proven this system to be skewed. Because of it, a truly excellent teacher may now leave teaching forever. This ruling states that if under VAM a teacher is found "ineffective" and the other 60% of the rating found that teacher effective, you cannot still rate the teacher as being ineffective. This is a ruling that makes sense.
