Public Schools HAVE to accommodate ALL residents who wish to enroll. During the baby boom and again during the white flight to the suburbs in the late 1960s many public schools went on double sessions. This made much better use of the buildings than having them sit empty from 2:30 PM on.
As for having to supply kosher food to students..NO it is not a requirement. No student is forced to eat school lunch in public school, nor is forbidden to bring lunch from home (subject to restrictions such as peanut butter). The largest city in , Bridgeport, serves free lunch to all students. They do not serve any pork products, not because of Jewish students, but a growing Muslim immigrant population.
