A group of visionary community leaders, educators and parents in southern Connecticut gathered in 2006 to explore the possibility of building a pluralistic Jewish high school that would serve Jewish families from Greenwich to New Haven.

 By 2007, the Board of Trustees - eighteen distinguished volunteers representing the religious and geographic diversity of the southern Connecticut Jewish community - established the Jewish High School of Connecticut.  Without delay, JHSC registered with the Internal Revenue Service as a 501(c)3 non-profit organization.  

Rabbi Edward Harwitz was appointed by JHSC as founding Head of School in July 2008.

JHSC is the beneficiary of a leadership gift from Michael Steinhardt and receives funding from the Jewish Federation of Greater New Haven, the Jewish Foundation of Greater New Haven, the United Jewish Federation of Greater Stamford, New Canaan and Darien, the UJA/Federation of Westport/Weston/Wilton/Norwalk and the  Annual Campaign of the UJA Federation of Eastern Fairfield County. JHSC is a School Subscriber of the National Association of Independent Schools (NAIS), a member of RAVSAK: the Jewish Community Day School Network and received a New Schools Grant from the Partnership for Excellence in Jewish Education (PEJE).
