Abstract
This article examines a value-added model to rate schools, taking into account varying characteristics of students entering the schools, including poverty, race, mobility, and stability. The model uses regression to separate the influence of demographics that are outside the schools’ control from those under school control. This value-added model leads to school ratings that compare actual performance to performance predicted by poverty rates. Even after adjusting for poverty, some schools consistently outperform others on a wide range of tests over a 5-year period, whereas other schools consistently perform at the bottom. Finally, this article discusses uses that can be made of this model.
