The Mandel Teacher Educator Institute (MTEI) is a program that strengthens the Jewish community by developing educational leaders – “teachers of teachers” – who are spearheading powerful and innovative professional development experiences for their institutions and communities. We believe that ongoing, substantive professional development for educational leaders and teachers is central to revitalizing Jewish education. MTEI’s intensive two-year program that consists of six, 4-day seminars with assignments in the field between meetings is a building block toward this goal.
