Training Within Industry

The Training Within Industry (TWI) service was created by the United States Department of War, running from 1940 to 1945 within the War Manpower Commission. The purpose was to provide consulting services to war-related industries whose personnel were being conscripted into the US Army at the same time the War Department was issuing orders for additional matériel. It was apparent that the shortage of trained and skilled personnel at precisely the time they were needed most would impose a hardship on those industries, and that only improved methods of job training would address the shortfall . By the end of World War II, over 1.6 million workers in over 16,500 plants had received a certification.
