This month, Navon is launching the first wave of a new Jewish School Census, focusing initially on part-time, supplemental Jewish schools. These schools remain the largest component of American Jewish education, yet we know very little about the scope of supplemental Jewish education in North America. An established baseline for enrollment at these schools would be an invaluable tool for professionals aiming to increase the relevancy and impact these schools have on their students. Updating that baseline every year can yield insight into how specific communities are able to “move the needle.”
