Suppose that your local school district wants to implement a program to assess teacher quality and success and to use that assessment as part of the evaluation of teachers that may affect their salary or retention. What are the advantages and disadvantages of using student test scores to evaluate teachers? What factors might influence student test scores other than the “quality” of a specific teacher? If one is concerned that learning in prior classes might influence current test scores, how could one separate the effect of a single class or teacher? What might be included in teacher assessment other than test scores?
