To understand how day schools are measuring up to their potential as incubators of Jewish commitment, a team of researchers undertook to visit some 19 schools and learn first-hand how they enact their Jewish mission. The eight-member team – consisting almost entirely of former day school heads who now work in other arenas in the field of Jewish education – spent time observing schools between the spring of 2012 and the end of the 2012-13 school year. Usually in teams of two, the observers focused their attention on the ways day schools enact their self-defined Jewish mission. The Case Study team consisted of Michael Berger, Josh Elkin, Cheryl Finkel, Reuven Greenvald, Pearl Mattenson, Alex Pomson, Jack Wertheimer and Tali Zelkowicz.
