National Youth Administration The National Youth Administration (NYA) was a New Deal agency sponsored by the Presidency of Franklin D. Roosevelt in the United States that focused on providing work and education for Americans between the ages of 16 and 25. It operated from June 26, 1935 to 1939 as part of the Works Progress Administration (WPA). Following the passage of the Reorganization Act of 1939, the NYA was transferred from the WPA to the Federal Security Agency. In 1942, the NYA was transferred to the War Manpower Commission (WMC). The NYA was dissolved in 1943.
