You get one SIFT retest, and Army regulation puts it on the 46th day after your first attempt. Writing these guides, we have not found a clearer case of an outdated number circulating unchallenged. Most sites covering the SIFT still say 180 days, and that figure describes a different rule.
The Selection Instrument for Flight Training gates Army aviation for warrant officer candidates and commissioned officers alike.
The Structure of the Test
Department of the Army Pamphlet 611-256-2 describes the battery as four components divided into seven subtests, taking roughly two and a half hours.
| Component | Subtest | Time and length |
|---|---|---|
| Perceptual Speed and Accuracy | Simple Drawings | 2 minutes, 100 questions |
| Perceptual Speed and Accuracy | Hidden Figures | 5 minutes, 50 questions |
| Army Aviation Information Test | Single subtest | 30 minutes, 40 questions |
| Spatial Apperception Test | Single subtest | 10 minutes, 25 questions |
| Cognitive Abilities | Reading Comprehension | 30 minutes, 20 questions |
| Cognitive Abilities | Math Skills | 40 minutes, adaptive length |
| Cognitive Abilities | Mechanical Comprehension | 15 minutes, adaptive length |
A non-scored background information section adds ten minutes. Simple Drawings shocks most candidates. It runs 100 questions in two minutes, which works out at just over a second each.
Math Skills and Mechanical Comprehension are adaptive, so their length varies with how you answer. The other subtests are fixed.
The Score You Need
The pamphlet states the minimum qualifying score as 40, on a scale from 20 to 80 with a mean of 50 and a standard deviation of 10.
The scale tells you something the number alone does not. A 40 sits one full standard deviation below the average candidate, so the pass mark is genuinely a floor rather than a target. Roughly the bottom sixth of candidates fall under it.
Clearing 40 makes you eligible. It does not make you competitive, and a selection board reads your score alongside your record, your flight physical and the rest of the packet.
Where the 180-Day Myth Comes From
Both current Army sources agree on the retest window. The pamphlet states the examinee may retest one time and no earlier than the 46th day following the previous attempt. Army Regulation 611-110 repeats it and adds that the applicant's immediate commander may approve the retest.
The 180-day figure comes from Army Regulation 611-5, which governs Army personnel testing generally and sets a six-month wait between retests. That rule carries an explicit exception for cases where retesting complies with the regulation applying to the specific test, and the aviation regulation is exactly that.
Older installation handouts still carry the 180-day wording, and so do most prep sites. Regulation 611-110 was revised in 2023, and its own summary of changes says it changed the SIFT retest requirement. If someone tells you to wait six months, ask which document they are reading.
Passing Closes the Door Behind You
Regulation 611-110 states that once an applicant attains a qualifying score, they cannot retest. There is no route to improve a passing score.
That reverses the usual calculation. On most tests a marginal pass is something you can work on later. Here a 41 is permanent, and it goes to every board you ever face for aviation.
So treat the first sitting as the one that counts. Candidates who sit it early to see the format have converted a two-attempt test into a one-attempt test, and if they passed marginally, into a score they cannot fix.
What the SIFT Gates
Regulation 611-110 covers the selection of Army aviation officers and warrant officers. Its eligibility provisions reach warrant officers, warrant officer candidates, lieutenants, captains and individuals in training for a commission. Cadets at West Point and in Army ROTC are eligible to sit it as well.
It also gates the medical process. The regulation states that no applicant may request a flight duty medical examination until they have achieved a passing SIFT score. That puts the test first in the sequence rather than alongside the physical.
For the warrant officer flight path, a General Technical composite of 110 sits alongside it. The Army's rotary wing aviator page lists that figure, and the published remedy for falling short is retesting through the in-service Armed Forces Classification Test. Our GT score guide covers how that composite works.
What Preparation Helps
The Army Aviation Information Test is the clearest target. It is 40 questions of straight knowledge about helicopter aerodynamics, aircraft components and flight principles, and none of it is intuitive to someone who has never studied rotary wing flight. Candidates who read a basic helicopter aerodynamics text move this subtest more than any other.
Spatial Apperception is next. You are shown a view from a cockpit and asked to identify the aircraft's attitude relative to the ground. The format is learnable with practice, even though the underlying skill is harder to build.
Simple Drawings and Hidden Figures reward familiarity with the format above all. At just over a second per question on Simple Drawings, the difference between a candidate who has seen the layout and one who has not is large.
Reading Comprehension, Math Skills and Mechanical Comprehension overlap with material from the ASVAB, so work you did to enlist carries over.
How the SIFT Compares to the Other Flight Tests
Each branch runs its own aviation screen, and the rules differ enough that experience with one is a poor guide to another.
The Navy and Marine Corps use the ASTB-E, which allows three lifetime attempts with 30 days between them, and replaces your earlier scores with the newest result. The Air Force uses the AFOQT, which superscores and keeps your best composite from every sitting. Our guides cover the ASTB-E and the AFOQT separately.
The SIFT sits between them on attempts and behind both on flexibility. Two attempts, a 46-day gap, and no retesting once you pass. A candidate weighing branches should factor that in, because the same marginal score is recoverable in one service and permanent in another.
Who Should Not Book a SIFT Date Yet
Anyone who has not studied aviation information should wait. It is the subtest with the most learnable content and the one where an unprepared candidate loses most, and you only get two attempts in a lifetime.
Candidates whose GT composite sits below 110 should also handle that first. A passing SIFT does not help a warrant officer flight packet that fails on the composite, and raising the composite through the AFCT takes months.
What the Score Does Not Cover
A qualifying SIFT is one line in an aviation packet. Selection boards read your record, your evaluation reports, your commander's recommendation and your flight physical alongside it, and a strong score does not carry a weak packet.
The medical side fails more candidates than most expect. Vision standards, height and weight, and the Class 1A flight physical each end applications that cleared the test comfortably. Because the regulation blocks you from requesting that physical until you pass the SIFT, you may not learn about a disqualifying condition until after both test attempts are spent.
If you have any doubt about meeting the flight medical standards, raise it with a flight surgeon early. Finding out after a marginal pass is the worst sequence available.
What Would Change This Answer
If the Army revised Regulation 611-110 again, the retest window could move, since the 46-day rule arrived in the 2023 revision and replaced something else. A change to the two-attempt limit would reduce the pressure on a first sitting considerably. Both are worth re-checking against the regulation rather than against a website before you commit.
Our military tests guide covers the other selection tests across the branches. Read the aviation information material first, sit a timed practice run on Simple Drawings, and book the test only when both hold up.
