The Naval Academy received accreditation as an approved "technological institution" in 1930. In 1933, President Franklin Roosevelt signed into law an act of Congress providing for the Bachelor of Science Degree for the Naval, Military, and Coast Guard Academies. The Class of 1933 was the first to receive this degree and have it written in the diploma. In 1937, an act of Congress extended to the Superintendent of the Naval Academy the authority to award the Bachelor of Science degree to all living graduates. The Academy later replaced a fixed curriculum taken by all midshipmen with the present core curriculum plus 22 major fields of study.
