Limited research exists on Jewish educational leadership practices and conditions for school leader success. The few studies on educational leadership that have been published in the past 15 years primarily drew on case studies. There is a need for research that includes a large sample of Jewish day school leaders and examines leadership practices and the conditions that influence them. This study is part of a three-year research project that aims to answer the research question: What is effective educational leadership in Jewish day schools, and how can it be nurtured and sustained?
