These models, which consider student growth on standardized tests, fall roughly into four categories: «value - added models» that do not control for student background; models that do control for student background; models that compare teachers within rather than across schools; and student growth percentile (SGP) models, which measure the achievement of individual students compared to other students with similar test score histories.

To avoid these risks, value - added models must fully control for background variables that could be persistently associated with any teacher.

Clearly, value - added models do not account for every factor that might contribute to student learning; the question is whether they account for enough variables so that any factors not controlled by the model are not persistently associated with teachers.
