A Jewish day school is a modern Jewish educational institution that is designed to provide children of Jewish parents with both a Jewish and a secular education in one school on a full-time basis. The term "day school" is used to differentiate schools attended during the day from their secular or religious "boarding school" equivalents where the students live full-time as well as study. The substance of the "Jewish" component varies from school to school, community to community, and usually depends on the Jewish denominations of the schools' founders. While some schools may stress Judaism and Torah study others may focus more on Jewish history, Hebrew language, Yiddish language, secular Jewish culture, and Zionism.
