Validation Engine for Observational Protocols

The Bill & Melinda Gates Foundation introduced the Measures of Effective Teaching (MET) project to develop and test multiple measures of teacher effectiveness. This document explores the overarching purpose and functionality of a validation engine, which was designed to help districts determine if their observation protocols routinely assign the highest ratings to teachers whose students grew the most, in terms of academic performance, and the lowest ratings to teachers whose students grew the least.
