Officer candidate school

Typically, officer candidates have already attained post-secondary education, and sometimes a bachelor's degree, and undergo a short duration of training (not more than a year) which focuses primarily on military skills and leadership.

Since OCS Portsea's closure in 1985, all Australian Army Officer training has been conducted at the Royal Military College, Duntroon in Canberra.

However, the 10-year program was incomplete by the time World War II broke out in the Pacific and ROSS training was subsequently stopped.

Nevertheless, many of its trainees were called to active duty to serve throughout the war mainly with the U.S. Army Forces in the Far East (USAFFE).

Early training was held at Camp Tinio, Bangad, Cabanatuan City, Nueva Ecija, Nichols Air Base in Pasay and Fort Bonifacio in Metro Manila.

OCS is a quad-service institution which trains officers of the Army, Air Force, Digital and Intelligence Service, and Navy.

In South Korea, Officer Candidate School (학사사관) were modeled on OCS programs of the United States Armed Forces.

Both ROKN and ROKMC officer candidates earn commissions together at Republic of Korea Naval Academy in Changwon, while their training programs are distinct.

In a similar vein to Sandhurst, Dartmouth and Cranwell also train future officers of many different foreign and Commonwealth militaries.

The courses generally last from six to seventeen weeks and include classroom instruction in military subjects, physical training, and leadership.

People may earn a commission in the United States Armed Forces through OCS or OTS, by staff appointment, through Reserve Officers Training Corps (ROTC), or through one of the five federal service academies.
