Research suggests that, among school-related factors, teachers matter most when it comes to a student's academic performance. Nonschool factors do influence student achievement, but effective teaching has the potential to help level the playing field.
Measuring Teacher Effectiveness
A Resource for Teachers, Administrators, Policymakers, and Parents
Many personal, family, and neighborhood factors contribute to a student's academic performance, but a large body of research suggests that, among school-related factors, teachers matter most. What's less clear, however, is how to measure an individual teacher's effectiveness.
It's a complex topic, and there are many factors that should be considered. RAND Education and Labor has applied its expertise to this and nearly every other aspect of the education system for more than three decades. This site is for teachers, administrators, policymakers, parents, and anyone else seeking objective, nonpartisan information on measuring teaching effectiveness.
