WACs between the ages of 21 and 28 who have passed the required entrance examinations and interviews, may be admitted to the Centers Officer Candidate School. The 17-weeks course combines purely academic studies with military subjects. Young women with college educations are given the opportunity to begin military careers as commissioned officers. Because the Women's Army Corps has no ROTC, the demand for officer personnel must be met by training women of qualified caliber in the Center's OCS.
