The Training Course in Personnel Administration , founded at Radcliffe College in 1937, was the beginning of business training for women at Harvard. HBS took over administration of that program from Radcliffe in 1954. In 1959, alumnae of the one-year program (by then known as the Harvard-Radcliffe Program in Business Administration) were permitted to apply to join the HBS MBA program as second-years. In December 1962, the faculty voted to allow women to enter the MBA program directly. The first women to apply directly to the MBA program matriculated in September 1963.
