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.
Students face many barriers on the path to a credential of value. Gateway math courses are one such hurdle, which is why we’re supporting Learnvia, a new nonprofit developed with Carnegie Mellon University to provide free, AI-enabled courseware that helps more students succeed in foundational math and stay on track.
This year brought major progress in making students’ pathways clearer and more connected—from new tools that simplify credit transfer to stronger, more student-centered advising models. Partners across the field are showing how technology and innovation can work together to remove barriers, expand opportunity, and ensure every learner has the support they need to move from high school to college and career.
