The mission of Naval Hospital Corps School is to develop, teach basic principles and techniques of patient care and first aid procedures and put forward Hospital Corpsmen into the fleet: aboard ships, aboard Naval Hospitals, Department of Defense medical facilities, with United States Marine Corps units, or elsewhere.
Previously there were hospital corps schools located in San Diego, CA and Orlando, FL, and Bainbridge, MD.
The Great Lakes A-School closed after the last class graduated on July 28, 2011.
The school relocated – along with the newly commissioned Naval Medicine Training Center command – to the Medical Education and Training Campus at Fort Sam Houston, Joint Base San Antonio, Texas.
[1] Corpsman A-School lasts 19 weeks and may change according to scheduling and holidays.
