The earliest predecessor to the Joseph Kushner Hebrew Academy was founded in 1942. In a merger with four Talmud Torahs in 1948, the school started its evolution into a
Jewish day school. From the original seven students, the school grew to approximately 400 students in its building on Clinton Avenue, Newark. In 1987, the school became the Joseph Kushner Hebrew Academy and moved to Livingston in 1996. The Kushner Yeshiva High School opened its doors in 2000 with 57 freshman students, a comparatively large enrollment for a new Yeshiva High School. Kushner Yeshiva High School was renamed to the Rae Kushner Yeshiva High School, in memory of the wife of
Joseph Kushner, by their son
Charles Kushner, one of the school's primary benefactors. The school is situated on a campus that features a building includes a 20,000-volume English-Judaic library, a 220-seat
Beit Midrash, a 600-seat auditorium, Holocaust Memorial Gardens, Holocaust studies center, hockey rink, and a multipurpose gymnasium. The school houses a program of the
SINAI Special Needs Institute, also known as SINAI Schools, an organization dedicated to serving the educational, psychological and emotional needs of children with special needs or complex learning disabilities. Children of below to above average intelligence with different degrees of learning disability, with a wide variety of behavioral characteristics are served, whose needs could not be addressed by traditional Jewish day school programs and curricula. ==Administration==
