The Jefferson School of Social Science was an adult education institution of the Communist Party USA located in New York City. The so-called "Jeff School" was launched in 1944 as a successor to the party's New York Workers School, albeit skewed more towards community outreach and education rather than the training of party functionaries and activists, as had been the primary mission of its predecessor. Peaking in size in 1947 and 1948 with an attendance of about 5,000, the Jefferson School was embroiled in controversy during the McCarthy period including a 1954 legal battle with the Subversive Activities Control Board over the school's refusal to register as a so-called "Communist-controlled organization."
With the Communist Party in membership decline and financial chaos, the Jefferson School was forced to close its doors in 1956 in the face of government pressure.
The Jefferson School of Social Science was established by the Communist Party USA (CPUSA) in 1943 as part of that organization's effort to expand the teaching of Marxism to the working class. Communists of the day believed that Marxism was a form of science which it believed was being willfully ignored in the public schools and sought to correct what it viewed as a systemic educational shortcoming. Moreover, the Communist Party sought to bolster community goodwill through its efforts as part of its Popular Front effort to integrate itself into American society.
Unlike its predecessor, the New York Workers School, the Jefferson School was not focused upon the recruitment and training of new party members but was rather conceived as tool for more broad outreach into the community. The school did contain within it a more traditional apparatus for training of professional party cadres, however, an Institute of Marxist Studies which conducted a three-year program of study.
The Jefferson School was housed in a 9-storey building located at 575 Sixth Avenue in Lower Manhattan. The school was built around a library of 30,000 volumes and offered scores of classes each term covering history, politics, trade union affairs, ideology, and the sundry social sciences. In addition to "serious" topics, the Jefferson School added courses of a more whimsical or apolitical nature, including such topics as creative writing, art appreciation, health, interior decorating, and personal beauty on a budget. Traditional lecture-based adult education was further supplemented by the Jefferson School's hosting of periodic public events, including single-admission lectures, workshops, musical concerts, and dramatic performances.
