"It seems as though New York City newspapers are going to receive the value-added scores of the city’s public school teachers, and publish them in an online database, as was the case in Los Angeles.*
In my opinion, the publication will not only serve no useful purpose
educationally, but it is also a grossly unfair infringement on the
privacy of teachers. I have also argued previously
that putting the estimates online may serve to bias future results by
exacerbating the non-random assignment of students to teachers (parents
requesting [or not requesting] specific teachers based on published
ratings), though it’s worth noting that the city is now using a
different model.
That said, I don’t think there’s any way to avoid publication, given
that about a dozen newspapers will receive the data, and it’s unlikely
that every one of them will decline to do so. So, in addition to
expressing my firm opposition, I would offer what I consider to be an
absolutely necessary suggestion: If newspapers are going to publish the
estimates, they need to publish the error margins too."
