On August 9, 2012, the Institute of Education Sciences (IES) convened a meeting of researchers and U.S. Department of Education (ED) and IES staff to discuss recent advances in measuring teacher effectiveness. The objectives of the meeting were to: (1) Identify and discuss recent advances in the use of value-added models (VAMs) and student growth models (SGMs) as one measure of teacher effectiveness, including their implications, applications, and limitations for practicing educators; and (2) Identify considerations for future research. Participants from the research community were carefully chosen to represent a broad range of academic disciplines, expertise and perspectives. Each participant from the research community was asked to share in advance of the meeting a two-page written summary of their views on the implications of recent advances in value-added and SGM measures. These briefs are presented here. (Individual briefs contain references.) [For the meeting summary, see ED539039.]
