In the United States, the National Defense Cadet Corps (NDCC) was the forerunner to the current Junior Reserve Officers' Training Corps (JROTC) program and is essentially identical to it with just one exception: The NDCC is funded internally by the schools that opt for a military training system like JROTC but without any financial assistance from the Department of Defense.
At the time, JROTC graduates earned a certificate making them eligible to receive a commission in the Army Reserve at age 21.
Following World War II, when peacetime funding had become tight, JROTC suffered from lack of support.
As of 2012, the previous laws were rescinded and the requirements for all NDCC branches (Army, Marine, Navy, and Air Force) became standardized.
As with JROTC units, the U.S. military prescribes the curriculum and materials for instructor and cadet use, as well as legal forms and other supplies that meet regulations required to successfully administer the program.
