This article is one of the first to estimate the effects of features of teachers' preparation on teachers' value added to student test score performance.
In this paper, we investigate the persistence of teachers' value-added effects on student learning over multiple years and across subject areas.
Rob Manwaring of the research group Education Sector has suggested that districts release a breakdown of teachers' value-added scores at every school, without tying the individual scores to teachers' names.
Using student test scores as a measure of teacher "value" will further restrict what is taught.
The most highly promoted evaluation schemes statistically analyze year-to-year changes in individual test scores, yielding an estimate of teacher "value added".
For the Los Angeles area, for example, it's not in Pacoima or Watts — but rather in Beverly Hills, Malibu, Pacific Palisades or Palos Verdes — that you will find the highest scores on California's Academic Performance Index, regardless of teacher "value added" scores in these high-performance schools.
"Some school districts are interested in using these measurements of teacher value to make personnel decisions on hiring and promotions," Chamberlain says.

Different tests, different answers: The stability of teacher value-added estimates across outcome measures.
It has become commonplace to measure teacher quality in terms of teacher value-added.
