The CNC program began on 1 July 1943 and ended with the last group of graduating students on 31 December 1948and included three enrollment periods; the first term was in 1943, the second in 1944, and the third and final term was in 1945. During this time, 179,294 students enrolled in the program and 124,065 of them graduated from the participating nursing schools and became registered nurses. The main cause of student withdrawals was homesickness; some married students withdrew to be with their husbands when they were released from the military; others when the hostilities ceased; some failed in their studies; others left for health reasons; and some left because of the stress of a nursing career.
