The DLAB (Defense Language Aptitude Battery) is the U.S. military's standardized test for identifying service members with the aptitude to learn foreign languages. Unlike proficiency exams, the DLAB tests your ability to absorb entirely new grammatical rules, sound patterns, and linguistic structures you have never seen before.
This guide covers everything about the DLAB practice test: what the exam tests, how it is scored, which scores open which languages, and a 4-week study plan backed by the methods that have worked for military linguist candidates across the Army, Navy, Air Force, and Marines.
Part 1 of the DLAB presents a miniature invented language with its own grammatical rules. You receive a short grammar guide and must apply those rules to translate simple phrases. This part tests your ability to absorb and apply unfamiliar syntax โ the core skill of language learning.
Part 2 uses audio recordings of a constructed oral language. You must identify stress patterns, match sounds to symbols, and recognize rule-based patterns from what you hear. This section evaluates phonological aptitude โ how well you perceive and categorize unfamiliar sounds.
The DLAB uses a scaled score system (0โ164). Raw scores from both parts are combined and scaled. There is no penalty for wrong answers โ attempt every question. The scaled score determines which language categories you qualify for, from Category I (Spanish, French) to Category IV (Arabic, Chinese, Japanese, Korean).
| Pros | Cons |
|---|---|
| No prior foreign language knowledge is required โ the test is intentionally designed for complete beginners | The audio section requires distinguishing subtle stress and sound differences in recordings you cannot replay |
| The grammar rules are provided during the test โ you are not memorizing rules in advance, only applying them quickly | Timed pressure compounds errors โ there is no reviewing and returning once you advance past a section |
| The audio section rewards natural phonological awareness, which many people have without realizing it | There are no official practice materials released by the military โ all prep relies on third-party simulations |
| Practice tests can meaningfully improve performance โ the rule-application skill is trainable | Scores cannot be appealed โ if you score below the threshold, you must wait out the retest period |

The DLAB (Defense Language Aptitude Battery) is administered by the US military primarily to assess which capability?
Answer: A. A recruit's potential to learn a foreign language
The DLAB measures language-learning aptitude โ potential, not current ability.
In Language X, 'ban' and 'pan' are different words with different meanings. What does this tell you about /b/ and /p/ in this language?
Answer: B. They are separate phonemes (distinctive sounds)
Because swapping /b/ for /p/ changes the word's meaning (ban โ pan), these sounds are separate phonemes โ they create minimal pairs. A minimal pair proves that two sounds are phonemically distinct in a given language.
In a tone language, 'ma' with a high tone means 'mother' and 'ma' with a low tone means 'horse.' What role does pitch play in this language?
Answer: C. It distinguishes word meaning (lexical tone)
When pitch differences change the meaning of otherwise identical syllables, the language has lexical tone. The same consonant-vowel sequence /ma/ has completely different meanings depending on its pitch pattern. Mandarin Chinese has four tones that function this way.
In a test language, underlining a symbol marks it as silent. The word written as b-rฬฒ-e-n (with underlined r) is pronounced:
Answer: B. /ben/
The underlined r is silent, so only b, e, and n are pronounced, yielding /ben/.
