computer centers, libraries, a sports gymnasium, and a rooftop playground. Philanthropist Ronald Perelman provided nearly half of the $15 million funding for the campus, which opened in 1995. Curriculum School is in session six days a week, excluding Shabbat (Saturday), with a half-day scheduled on Fridays to accommodate Shabbat preparations. The school day runs from 9 am to 4 pm, with a half-hour break for lunch. Judaic studies – including Bible, Midrash, Jewish law, Jewish history, Hebrew, Yiddish, and the writings of the Chabad Rebbes – are taught in the mornings. Secular subjects such as English, mathematics, geography, science, and American history are taught in the afternoons. While in previous decades the language of instruction was Yiddish, the school now teaches religious subjects in Hebrew and secular subjects in English. Yiddish is taught as a second language. An optional Yiddish track is offered in first grade. As a private school certified by the State of New York, Beth Rivkah is required to teach science (biology and chemistry), history (U.S. and world history), English literature, and mathematics (algebra, geometry, and trigonometry), among other subjects.

In high school, where students are required by the New York Board of Regents to study from specific textbooks, teachers append their own notations to pages describing theories such as the Big Bang and evolution to inform students of what they consider the Torah point of view on these topics. Novels read in English literature classes are also vetted for compliance with Chabad philosophy and religious belief. Beth Rivkah teachers employ pedagogical techniques such as "group work, cooperative learning, and multiple-intelligence methods", and attend both regional and national workshops sponsored by Chabad to improve their pedagogical methods. Summer camp The Crown Heights school runs a 7-week day camp on the premises each summer for preschool through seventh grade. The camp is divided into three divisions: Kiddie Camp (Pre-1A), Younger Division (Grades 1 and 2) and Older Division (Grades 3 through 7). Student body Beth Rivkah accepts all students regardless of religious affiliation or educational background. It also accepts students who cannot afford full tuition. The school has weathered financial shortfalls due to its tuition policy. In September 2014 the Pre-1A,
