The view that the returns to public educational investments are highest for early childhood interventions stems primarily from several influential randomized trials - Abecedarian, Perry, and the Early Training Project - that point to super-normal returns to preschool interventions. This paper...

This paper describes a new method for assigning letter grades to students based on their raw scores, which I call Multi-Curve Grading (MCG). The intuition behind the method is that a class can be composed of several different subgroups, each of which should be assigned a different grade. In...
