Is It Just a Bad Class? Assessing the Stability of Measured Teacher Performance. CEDR Working Paper No. 2010-3.0
Goldhaber, Dan; Hansen, Michael
Center for Education Data & Research
Economic theory commonly models unobserved worker quality as a given parameter that is fixed over time, but empirical evidence supporting this assumption is sparse. In this paper we report on work estimating the stability of value-added estimates of teacher effects, an important area of investigation given that new workforce policies implicitly assume that effectiveness is a stable attribute within teachers. The results strongly reject the hypothesis that true teacher effectiveness is perfectly stable within teachers over time, but the estimated stability is consistent with performance measures from other occupations. Finally, we find that little of the changes in teacher effectiveness estimates within teachers can be explained by observable characteristics. Fitting the Hybrid Model is appended. (Contains 6 figures, 8 tables, and 35 footnotes.)
