The Saul Zaentz Early Education Initiative at the Harvard Graduate School of Education (HGSE) promotes the knowledge, professional learning, and collective action necessary to cultivate optimal learning environments and experiences. The Zaentz Initiative pursues interlocking strategies for impact: conducting research to drive policy and practice, designing and spreading high-quality professional learning, and pioneering a fellows program to build a pipeline of new leaders. The early education field can engage with the initiative through the Zaentz Professional Learning Academy, Early Learning Study at Harvard (ELS@H), and Zaentz Fellows Program. In July 2016, the Harvard Graduate School of Education launched the Saul Zaentz Early Education Initiative, with a generous gift from the Saul Zaentz Charitable Foundation.
