Ben-Avie and Comer describe how Jewish day schools and the Yale Child Study Center's School Development Program (SDP) share a common agenda regarding the aim of education. The foundational science of education is child development, advocates James P. Comer in such seminal works as "School Power" (1980) and "Waiting For A Miracle" (1998). SDP, the educational change initiative founded by Comer, informed the design of the current study, which is an empirical exploration of how the climate of relationships in Jewish day schools impede or promote the process through which children forge a relationship to the Jewish people.
