Officer Training School (OTS) is a United States Air Force and United States Space Force officer accession and training program located at Maxwell Air Force Base in Montgomery, Alabama. It is administered by the Jeanne M. Holm Center for Officer Accessions and Citizen Development, a component of Air University responsible for Department of the Air Force officer recruitment, training, and citizenship programs.

OTS is one of the Department of the Air Force's officer accession programs and provides initial officer training for college graduates, prior-enlisted personnel, and selected direct commission officers entering the Air Force, Air Force Reserve, Air National Guard, and Space Force. and the current Commandant of OTS (OTS/CMDT) is Colonel Roxanne T. Toy, USAF.

During peacetime, OTS is usually the smallest commissioning source in the USAF, producing fewer officers per year than AFROTC and the United States Air Force Academy (USAFA). However, it possesses the capability to surge when USAF requirements dictate and exceed the combined annual officer production of both USAFA and AFROTC. Given its shorter lead time for officer production (currently 8.5 weeks versus the typically 4-year pre-commissioning process for USAFA and AFROTC cadets), OTS is the commissioning source used to balance out USAF officer manning as deemed necessary by the Air Force.

The number of officers commissioned through OTS fluctuates considerably as their numbers are largely influenced by the number of graduating cadets through the USAF Academy and AFROTC, as well as being the first place the Air Force cuts when they have a surplus of cadets through the other two sources. Given this reality, OTS has often surpassed USAFA officer production during wartime periods such as during the Vietnam War in the 1960s and early 1970s or the Reagan defense buildup of the 1980s. During these periods of contractions, OTS produces few officers, making selection for the OTS program particularly difficult and competitive for college graduates, especially those with no prior enlisted service, particularly USAF enlisted service.

Interested applicants for OTS typically contact Air Force recruiters specializing in officer (versus enlisted) accessions. Recruiters will screen candidates, provide application details and schedule applicants for the Air Force Officer Qualifying Test (AFOQT). The AFOQT covers numerous test batteries assessing math, verbal, and analytical skills, as well as measuring pilot and navigator/combat systems officer potential for those applicants aspiring to be aeronautically rated officers. AFOQT scores, college GPA, previous enlisted performance evaluations if a current or former enlisted member, and, if applicable, previous pilot skills as either an FAA-certified civilian pilot and/or as a U.S. Army warrant officer / Army Aviator will all figure into the selection process, although the selection process strives to employ a composite or "whole person" approach.

OTS applicants will be given an opportunity to apply for Air Force career fields that correspond with the applicants' expertise and/or desires and will be interviewed by active duty Air Force officers as well as receive a military medical examination for flying or non-flying duty as appropriate. Applicants will then be screened by a centralized, periodic, OTS Selection Board conducted by the Air Force Recruiting Service, a component of the Air Education and Training Command. Applicants will be notified of acceptance or rejection by their recruiter pending release of the board results.

If not already on active duty as enlisted personnel in the armed forces, selectees for OTS will subsequently enlist in the Air Force Reserve via the Delayed Enlistment Program and will be assigned an OTS class date. Non-prior service college graduates will enlist in the rank of Airman 1st Class (E-3) while prior service enlisted personnel will be enlisted in their current or highest prior pay grade. Upon arrival at OTS, all personnel will be advanced to pay grade E-5 (unless prior enlisted already holding a higher pay grade), but will hold the rank of Officer Trainee versus USAF Staff Sergeant.

Selection for OTS is highly competitive, with selection rates varying dependent on the needs of the Air Force. For example, boards conducted circa 2010–2012 had selection rates in the 20% range due to budgetary reductions / force reductions being imposed on the Air Force at that time. However, by 2017, selection rates had increased to the 65% range or greater, reflecting the increased commissioned officer needs of the service.

Officer Training Course

Per Air Force Instruction (AFI) 36-2013, personnel attending Officer Training School's 8-week program must have a baccalaureate level degree or higher in either technical or non-technical fields. Technical fields may include any ABET-accredited engineering degree or other fields in high demand by the Air Force. Non-technical degrees are more common, and therefore applying with a degree in such a field is very competitive. Applicants can apply for aeronautically rated or non-rated Line Officer of the Air Force (LAF) positions. Rated positions are flying related -- Pilot, Combat Systems Officer (previously known as Navigator), Remotely-Piloted Aircraft (RPA) Pilot, or Air Battle Manager. Non-rated positions fall into two categories: non-rated operations, such as missiles, intelligence, space, cyber, or weather, and non-rated support, such as aircraft maintenance, missile maintenance, logistics, civil engineer, security forces, or communications.

The first few weeks of training are geared toward orienting the cadet with Air Force standards. The focus is on physical training, drill and ceremonies, and academics. Cadets will be expected to work with their fellow flight and squadron members to accomplish specific tasks as required by their Flight Commander and the Cadet Wing. They will also attend multiple classes in an academic environment. Later in the program they will attend field training exercises, projects, small arms training, and building team skills by overcoming challenges in a simulated deployment environment.

To graduate, cadets must meet or exceed physical standards, academic standards, and military bearing standards. Military bearing includes the ability to write and verbally brief, lead the flight, and perform duties within the Cadet Wing.

Upon graduation, OTS graduates may receive either Regular or Reserve commissions as second lieutenants in the Regular United States Air Force, the Air Force Reserve, or the Air National Guard, as appropriate to their original source of entry and contract. The new second lieutenants will be appointed in either pay grade O-1, or O-1E if they have prior cumulative active service as a warrant officer or as an enlisted servicemember in any branch or component of the U.S. armed forces for at least 4 years and 1 day. If any portion of their prior service was in a reserve component and not served in an active duty status, then inactive duty reserve retirement points may be used to qualify for O-1E. If the combination of creditable active duty days and inactive duty points equals 1,460 (equivalent to exactly 4 years and 1 day of cumulative qualifying active and inactive duty), the pay grade O-1E is assigned, which is a significantly higher starting basic pay level than O-1, and remains higher until promoted to O-4.

Curriculum

The academic curriculum and coursework are derived from five Program Learning Outcomes: Leader of Character, Warfighter, Effective Communicator, Strategic-Minded Officer, and Disciplined Professional. These outcomes are intended to develop ethical leadership, understanding of Department of the Air Force doctrine and the nature of war, professional communication, strategic awareness, and adherence to Department of the Air Force standards.

The course includes a pre-course assignment followed by an in-residence academic curriculum organized into five modules. Module 1 introduces officer trainees to military customs and courtesies, dress and appearance standards, Department of the Air Force core values, the oath of office, the U.S. Constitution, resiliency, and military professionalism. Module 2 emphasizes leadership and communication skills, including self-awareness, full-range leadership, followership, team building, problem solving, critical and creative thinking, conflict management, counseling, organizational climate, evaluation systems, performance statements, and peer feedback.

Module 3 focuses on military and operational foundations, including civilian control of the military, national security, the nature of war, Department of the Air Force contributions to joint operations, military planning, force generation, Agile Combat Employment, military justice, lethality, military-style briefings, and global security issues. Module 4 covers more advanced strategic and operational topics, including air and space capabilities, force packaging, space operations, nuclear operations, international relations, terrorism, strategic competition with China, Russia as a global threat, the law of war, and global hot spots briefings. Module 5 prepares trainees for transition to commissioned service through instruction on Wingman and Guardian intervention, social media and disinformation, career progression, first assignment expectations, and final peer and instructor feedback.

Officer Training School-Abbreviated

OTS-A is a 5-week course for professionals who have received a direct commission. Typically, these officers have advanced, graduate-level degrees, often masters or doctorates. Professions include chaplains, physicians (MD or DO), physician assistants, podiatrists, optometrists, dentists, pharmacists, clinical and counseling psychologists, nurses, social workers, lawyers, and veterinarians. They often enter at an advanced rank, such as first lieutenant (O-2) and sometimes as captain (O-3) in compensation for their higher levels of education, and in some cases, experience. Officers can be commissioned up to the rank of colonel (O-6) if they possess the level of experience necessary.

With the exception of those officers previously commissioned as line officers through USAFA, AFROTC, the 8-week program of OTS, or the Air Force Nurse program of AFROTC, most chaplains, judge advocates general (i.e., lawyers), and medical personnel go through OTS-A.

Medical students and related medical professions students that have received a Health Professions Scholarship Program scholarship or those attending the Uniformed Services University of the Health Sciences undergo OTS-A, and are commissioned as second lieutenants (O1) during their professional training.

OTS-A is responsible for developing medical, legal, and chaplain personnel into professional officers by instilling character, knowledge, and motivation essential to serve in the United States Air Force. The 23rd Training Squadron (23 TRS) provides a 23-training day Commissioned Officer Training course to instill leadership and officership skills in newly commissioned medical officers, judge advocates, and chaplains. The 23 TRS also conducts a 13-training day Reserve Commissioned Officer Orientation (RCOO) program for hard-to-recruit medical officers in the Air Force Reserve and Air National Guard.

The History of OTS

thumb|thumbtime=10:00|The film [[Wings Up (1943) helped promote the USAAF OCS]]

When the Aviation Cadet (AvCad) Program proved insufficient to meet wartime commissioned officer requirements, the United States Army Air Forces established the Officer Candidate School (OCS) on 23 February 1942 at Miami Beach, Florida, its mission being to train and commission members from the enlisted ranks.

OCS moved to the San Antonio Aviation Cadet Center (now Lackland AFB), Texas, in 1944 and gained the additional mission of training officers directly from civilian status in September 1951.

OTS was organized at Lackland AFB, Texas, in November 1959, with the first OTS class (60-A) composed of 89 officer trainees, including 11 women, who graduated and were commissioned as 2nd Lieutenants on 9 February 1960. The number of OTS graduates has varied over the years, from 323 the first year to a high of 7,894 officers in 1967. OTS then became the sole organization for training future Air Force officers at Lackland AFB.

On 1 July 1993, Air Training Command (ATC) merged with Air University (AU) to form the new Air Education and Training Command (AETC), with Air University becoming a direct reporting unit (DRU) under AETC. OTS, which was formerly under ATC, and Air Force ROTC, which was formerly under AU, were then realigned under both AETC and AU.

Until 22 September 1993, Officer Training School was primarily located on the Medina Annex of Lackland AFB, Texas, with the last OTS class, Class 93-06, graduating from that location on that date. For a short period during the build up of the Air Force to meet the demands of the Vietnam War, as many as three OTS Squadrons were based directly at Lackland AFB. During the spring and summer of 1993, OTS gradually relocated to Maxwell AFB, Alabama, the home of Air University, commencing operations in interim facilities on 25 September 1993.

Historically, the USAF Academy had been (and continues to be) headed by a lieutenant general and Air Force ROTC had been headed by a major general or brigadier general, while OTS had been headed by a colonel. In February 1997, in an effort to reduce duplication of effort and streamline administrative and reporting procedures within AU, AFROTC and OTS realigned under a newly created umbrella organization, Air Force Officer Accession and Training Schools (AFOATS). Under this restructuring, OTS and AFROTC were placed under the leadership of individual USAF colonels (AFJROTC and CAP were also placed under individual USAF colonels), while general officer oversight for both OTS and AFROTC, representing three-quarters of Air Force officer production, was placed under one command, the AFOATS commander, a brigadier general.
