The DLAB score you need rises with the language you want, from 95 up to 110. Of the tests we cover, readers find this the hardest to get a straight answer about. The Army publishes a qualifying score for each of the four language difficulty categories, and the harder the language, the higher the bar.
The Defense Language Aptitude Battery is the strangest test in military selection, because it does not measure anything you already know.
What the Test Measures
Army Regulation 11-6 describes the DLAB as a quantifiable indicator of a person's aptitude to learn a foreign language in a formal training programme. Defense policy calls it the preferred battery for assessing aptitude for language learning.
The test constructs an artificial language, teaches you its rules as you go, and asks you to apply them. Knowing Spanish does not help. You succeed by picking up an unfamiliar grammatical system quickly, which is a different skill from having learned one before.
Some commonly repeated details about the format sit on weaker ground. The figures of 126 questions and roughly two hours do appear on a military server. The file carrying them turns out to be the preface of a commercial study guide rather than official policy. Treat the structure as approximate and confirm the day's arrangements with the test administrator.
The Scores You Need
Regulation 11-6 publishes qualifying scores by language difficulty category, and the Defense Language Institute's own catalogue lists the same four numbers.
| Category | Qualifying score | Languages |
|---|---|---|
| I | 95 | French, Italian, Portuguese, Spanish |
| II | 100 | German |
| III | 105 | Hebrew, Hindi, Persian Farsi, Dari, Russian, Serbian and Croatian, Tagalog, Thai, Turkish, Urdu |
| IV | 110 | Arabic, Chinese, Japanese, Korean, Pashto |
The Army floor for recruiting purposes is 95, and the regulation notes that most Army language requirements need 105 or higher. So a candidate aiming broadly should treat 105 as the working target rather than 95.
Certain courses set the bar higher again. The institute's basic special projects courses require a DLAB ten points above the standard minimum for that language, which puts Arabic at 120.
The ST 129 Bypass
Regulation 11-6 states that an ASVAB Skilled Technical composite of 129 or higher bypasses the DLAB entirely.
Check that before you book a test. A soldier with a strong ST composite may already qualify for language training without sitting the DLAB at all. Many candidates have never looked at that composite. Our line scores guide covers how it is built.
The Army's current page for the 35P signals intelligence voice interceptor makes the same point, listing the bypass alongside its other requirements.
Where the Circulating 35P Numbers Break Down
Search for the linguist requirements and you will find an ASVAB Skilled Technical score of 91 and a DLAB score of 107, repeated across dozens of sites.
The Army's current 35P page publishes different figures: a Skilled Technical composite of 101 and a DLAB of 85 or above for active duty applicants. Neither third-party number matches.
The 85 sits below the Army recruiting floor of 95 stated in Regulation 11-6, which is a real tension rather than a typo we can resolve. It plausibly works as an enlistment screening threshold with the language assignment settled later, and we could not confirm that reading from a published source. Take the Army's own page as the starting point and ask a recruiter to confirm the current requirement, because the authoritative job specification is not publicly available.
The composite behind linguist jobs is not in dispute. Linguist jobs run on Skilled Technical rather than the General Technical composite, and soldiers who spent months raising GT for a language job raised the wrong number.
Retaking It
Defense policy sets the wait at 180 calendar days from the last administration, unless your agency grants an exception to policy for you specifically. Where an exception is granted, there is no restriction on how soon you may retest, though nobody may take the DLAB more than twice in a rolling 12-month period.
Regulation 11-6 states the same six-month waiting period on the Army side. Requests to retest after already attaining a qualifying score go to the Army Foreign Language Program Service Program Manager, who is the sole approval authority for DLAB waivers.
One piece of older guidance is simply wrong. Older guidance circulating online describes a hard limit of two retests followed by a request to Human Resources Command, and that language comes from a superseded regulation. Current policy sets no lifetime cap.
The Other Services Set Their Own Bars
The category minimums are the Army's. Other services publish their own, and they do not match.
The Air Force sets 110 for its cryptologic language analyst and airborne cryptologic language analyst fields, above every Army category floor including Category I. Demonstrated proficiency on the Defense Language Proficiency Test can substitute.
The Marine Corps sets 100 for its cryptologic linguist field. That score may be waived case by case where substantial foreign language experience is demonstrated, with approval resting at Headquarters Marine Corps. A qualifying Defense Language Proficiency Test result can also stand in place of the DLAB.
So the number you need depends on the service as much as on the language, and a figure quoted for one branch tells you little about another.
What a Passing Score Buys
The DLAB opens the door to language training rather than to a specific language. Which language you are assigned depends on what the service needs when your training slot comes up, and a candidate who clears 110 for Arabic can be assigned Russian instead.
That surprises people who studied hard for a Category IV score expecting to choose. The score establishes the ceiling of what you can be taught, and the assignment process fills requirements.
Training itself is long. Category I courses at the Defense Language Institute run months, and Category IV courses run well over a year, followed by proficiency testing that continues throughout a career. Language-coded assignments then carry their own pay and retention incentives.
Note also that clearing the DLAB does not clear the clearance. Linguist jobs sit behind security investigations and citizenship requirements, and those end more applications than the aptitude test does.
Who Should Not Sit the DLAB
Anyone whose ST composite already clears 129 should check the bypass first. Sitting a test you do not need risks a low score on your record for no benefit.
Candidates with no interest in a language-coded assignment should also skip it. The DLAB gates linguist training and language-coded jobs, and it does nothing for a career outside those fields.
How It Fits With the Other Tests
The DLAB sits on top of the ASVAB rather than replacing it. You enlist on your AFQT percentile, qualify for a linguist job on your Skilled Technical composite, and then clear the DLAB for the language training itself.
Serving members who need a higher ST composite take the Armed Forces Classification Test through a base education office, which retests the whole ASVAB battery. Our retake guide covers how that works and what it risks.
What Would Change This Answer
If the Defense Language Institute published current DLAB specifications, including a maximum score and the test structure, most of the uncertainty here would resolve. If the Army published its authoritative job specification publicly again, the 35P conflict would settle. Both documents exist and neither is currently reachable.
Our military tests guide covers the other selection tests you may face. Check your ST composite for the bypass first, then confirm the current DLAB requirement for your target language and service with a recruiter or your education office.
