To become an air force commissioned officer, one must have a minimum of a bachelor's degree. How ever the eligibility criteria vary for different countries.
In a country like the United States Of America One can obtain a commission by being selected for the Air Force Reserve Officers Training Program (ROTC), by attending the Air Force Academy, or by graduating from Officer Training School (OTS).
The Air Force Officer Qualifying Test is a standardized one which is similar to the SAT and ACT that measures aptitudes, and is used to select applicants for officer commissioning programs or specific training programs. It is also used for selection into specific training programs such as pilot and navigator training.
