The John D. and Catherine T. MacArthur Foundation

The Models for Change initiative was the centerpiece of MacArthur’s $130 million effort to support rational, fair, and effective juvenile justice systems that recognize the developmental differences between juveniles and adults.

The John D. and Catherine T. MacArthur Foundation supports creative people and effective institutions committed to building a more just, verdant, and peaceful world.  In addition to selecting the MacArthur Fellows, the Foundation works to defend human rights, advance global conservation and security, make cities better places, and understand how technology is affecting children and society. 

The Foundation entered the field of juvenile justice in 1996 with support for an interdisciplinary MacArthur Research Network on Juvenile Justice and Adolescent Development, chaired by Laurence Steinberg. Having completed its work in 1996, the Network was designed to advance the scientific knowledge base about adolescent development and criminal behavior.
