Value added strikes again!

A Journal Sentinel article describes a new study from the Wisconsin Taxpayers Alliance comparing school districts' performance on the fourth grade reading exam. From the article, it appears the methodology used is very similar to one I have been pushing for several years: first predict the performance of a district based on its poverty rate and other available data. Then compare its actual performance to its predicted performance. At the very least this answers the most common complaint about school performance comparisons: that schools serving wealthier students have an unfair advantage.

The Taxpayers Alliance web site gives little information on the study's methodology or conclusions, but does offer to send a copy for free. I may comment further when I have had a chance to read the report.
