Establishing what we set out to do in formal Jewish education settings is often complex, and evaluating it can be slippery as we try to develop measures for what seems highly personal. Adding the variable of informal Jewish settings, with its socio-emotional or other affective agenda, only adds even more complexity to this problem. Still, in an increasingly demanding philanthropic marketplace, with board members, foundations and supporters caring deeply about the impact of their investment, it is our responsibility to show the value of their investment. We need to move beyond our ‘feelings,’ anecdotal assessments or purely numerical accounts of people in chairs. We need to be able to say with authority, integrity, and even some degree of empirical certainty that we are doing great work.
