Administration of the Social Security Act
The Social Security Board was responsible for administration of the original Social Security Act except for parts 1, 2, 3, and 5 of Title V (which were administered by the Children’s Bureau, then in the Department of Labor); part 4 of Title V which increased the appropriations authorized for carrying out the Act of June 2, 1920 and Title VI which authorized grants to the States for public health work.
The Social Security Board was transferred to the Federal Security Agency by Reorganization Plan No. 1 of 1939 and the Board’s functions were to be carried on under the direction and supervision of the Federal Security Administrator. Reorganization Plan No. 2 of 1946 transferred the functions of the Children’s Bureau and the functions of the Secretary of Labor under Title V of the Act to the Federal Security Administrator and the Board was abolished.
Effective March 31, 1995, the Social Security Administration was established as an independent agency by P.L. 103-296, §101, approved August 15, 1994, with a Commissioner of Social Security responsible for the exercise of all powers and the discharge of all duties of the Administration.
