Teachers matter. Nothing in a school day is more important for student achievement than the skills of teachers. Mathematica has a long history of studying how teachers are prepared for, supported, and perform in the classroom. Principals have also been shown to have an important influence on student achievement. Mathematica is studying intensive supports for principals and how they affect school, teacher, and student outcomes.
