Sandler soon began to file complaints against the University of Maryland and other colleges while working with NOW and the Women's Equity Action League (WEAL). Sandler later filed 269 complaints against colleges and universities, which led to the events of 1970. In 1970, Sandler joined U.S. House Representative Edith Green's Subcommittee on Higher Education of the Education and Labor Committee, and observed corresponding congressional hearings relating to women's issues on employment and equal opportunity. In these hearings, Green and Sandler initially proposed the idea of Title IX. An early legislative draft was then authored by Representative Patsy Mink with the assistance of Representative Edith Green. At the hearing, there were mentions of athletics. The idea behind the draft was a progressive one in somewhat instituting an affirmative action for women in all aspects of American education.
