In 1955, Galamison was elected to chair of the education committee of the Brooklyn branch of the
National Association for the Advancement of Colored People where he advocated for improving education for working class black and Puerto Rican students. In 1959 he founded The Parents' Workshop for Equality in New York Schools with the objectives of achieving racial integration in the schools of New York City, ensuring equal educational opportunity for all children, ending racial discrimination against black and Puerto Rican children, and improving education in the public schools. The Parents' Workshop was a grass roots organization initially housed at Siloam and later expanding to Brooklyn, Manhattan, Queens and the Bronx. In 1960, Galamison,
Annie Stein, Thelma Hamilton and other members of the Parents' Workshop began a campaign to pressure the
New York City Board of Education to integrate the schools. On the heels of the success of the Freedom Day boycott, Galamison planned for a follow-on boycott for March 16, 1964. He lost key support from the movements more conservative leaders, however, and due to the resulting organizational fragmentation, this boycott failed to gain sufficient popular support. and in 1967 Galamison founded a new organization called Citywide Coalition for Community Control. The efforts of this group led to the creation of demonstration schools with locally elected governing boards responsible for decisions related to hiring and curriculum. In July 1968,
Mayor John V. Lindsay appointed Galamison to the Board of Education. Rather than signify his final victory in his long battle against inequality in the schools, however, this appointment "confirmed his eclipse and that of the movement he led." After he failed in his bid for reelection to the School Board in 1969, Galamison retired from the political sphere. == Later life ==
