The MET project released progress reports as its research and analysis progressed. Through these reports, practitioners and policy makers have had quick access to the data developed through the project in order to begin thinking through the practical implications of the work prior to release of the final report.
In January 2013, the MET project released its third and final set of findings, which sought to answer three questions from practitioners and policy-makers: Can measures of effective teaching identify teachers who better help students learn?; How much weight should be placed on each measure of effective teaching when combining classroom observations, student surveys, and student achievement gains?; And how can teachers be assured trustworthy results from classroom observations?
Along with a brief summarizing all of the findings, and the three research papers detailing the technical methods, in January 2013 the MET project a released set principles for effective evaluation systems based on lessons learned over the three years of the study.
