Value-Added Modeling in Education

Student performance reflects many factors beyond their teacher's effectiveness, yet teacher evaluations often reflect how well their students do on standardized tests. RAND researchers are nationally recognized for their work using value-added modeling to distinguish a teacher's impact from factors such as individual ability, family environment, past schooling, and peer influence.

Value-Added Modeling 101: Using Student Test Scores to Help Measure Teaching Effectiveness

The author discusses the use of value-added models (VAMs) to estimate teacher contribution to student progress, account for students' prior characteristics, and enable relative judgments, as well as the limitations of VAMs.

The Challenges of Measuring Effective Teaching

While educators, policymakers, and parents may agree on the need for more effective teachers, they often use different criteria to judge whether schools are doing their job. Parents have varied priorities for what they want in teachers and in schools.

Is It Possible to Distinguish Good Teaching from Classroom Composition?

Measuring disadvantaged students' access to effective teachers requires examining the relationship between teachers' value-added estimates and the characteristics of their students. Research simulations investigate this relationship and may also help inform analysts' choices for the appropriate value-added models.

States Tackle Education's Holy Grail: Measuring a Teacher's Effectiveness

An accurate combined measure of teacher effectiveness would be the gold standard to capture and communicate information about the quality of educators. While the challenges to building such a measure are significant, research can help guide the way.

How Should We Measure Teacher Effectiveness?

Some of the most urgent and contentious debates taking hold in states and school districts around the country revolve around the question of how to accurately measure a teacher's effectiveness. A new RAND Education website provides objective, nonpartisan insights that can help inform the discussion.

Measuring Teacher Effectiveness

Research suggests that, among school-related factors, teachers matter most to students' academic performance. What's less clear is how to measure an individual teacher's effectiveness. RAND's reports, fact sheets, blog posts, and research briefs provide clarity on this important issue.

A Model for Teacher Effects from Longitudinal Data Without Assuming Vertical Scaling

The authors developed a "generalized persistence" (GP) model, a Bayesian multivariate model for estimating teacher effects that accommodates longitudinal data that are not vertically scaled by allowing less than perfect correlation of a teacher's effects across test administrations.
