Hornstein Students




            Our students are experienced professionals who are searching for meaningful work...

  ...and choose Hornstein to become critically informed, highly skilled professionals committed to shaping the future of the Jewish community. 

Each year, 10 to 15 qualified future Jewish professionals from all backgrounds are chosen to enroll in the Hornstein Program. A typical student has strong academic qualifications and several years of work experience in organizations such as Jewish camps, museums, Hillels and Jewish education; federations and JCCs; fundraising, community relations and start-ups; and work in overseas Jewish communities.

Some students are experienced professionals in other fields who are searching for meaningful work that brings their personal and professional identities closer together.

No matter what their background, our students chose the Hornstein Program to become critically informed, highly skilled professionals committed to shaping the future of the Jewish community.

The diversity of a typical class adds to its intellectual and professional excitement. Because graduates will be working in an increasingly diverse Jewish community, they confront tough questions about pluralism, tolerance and inclusion in their training. The educational experience at the Hornstein Program presents "living models" of good professional practice.
