Project Overview
From 2013 through 2018, Mathematica conducted a developmental evaluation of the deep-end reform to better understand what worked well, what could be improved, and what the lessons for the field were.
Funded and supported by the Annie E. Casey Foundation, several communities across the United States have undertaken deep-end reform designed to safely and significantly reduce out-of-home placement for juveniles, especially for youth of color.
