A review conducted by ten researchers of ten 'effective' Jewish supplementary schools of various sizes and denominations, and from various regions in the US. The report draws conclusions about factors contributing to the success of good schools, noteworthy characteristics of the schools, and policy recommendations for improving supplementary schools. The study presents six “noteworthy characteristics of good schools.” Good schools (1) work on building friendships and community, (2) go beyond teaching facts to allow students to work on meaning, (3) use experiential education, (4) actualize a clear vision, (5) value themselves and their students, and (6) involve not only students but their families. Wertheimer makes it clear that it takes “a combination of traits to forge a strong school.”
