There are no specific requirements that would preclude someone from taking the DLAB other than requiring you to be a service member or a dependent of a service member in good standing.
Furthermore, you can only take the exam if you haven’t taken it within 6 months. So, ever six months you have the option to retake it. Some sites say that you can’t take it again if you already passed once, but this is not true. Throughout all the source documents, there is NO mention of such. However, what we think this other “sources” are really referring to is the chances of being able to take it again. In most cases, 6 months will be too long before you can take it again. If you didn’t pass it the first time, your window of opportunity will have passed. If you were looking to become a cryptologist, the military won’t let you sit around for 6 months. They will probably put you into a different field. If you are applying for a program like Foreign Area Officer (FAO), you will probably miss that board’s convening and might have to take other orders that will preclude you from switching communities.
So, to ensure everyone is on the same page: You can take the test again after six months, but you window of opportunity might be gone after that six month wait is over.
For those of you looking for concrete evidence, here is DLI’s requirement list. This list comes straight from their official website. Hopefully, this too will convince those who were confused about the overall scores. Reading forum posts, and discussions on social media, many people believed the required scores to be something else. This is not true when it comes to DLI. What some people might be referring to is individual services saying that they “want a higher score” before they send someone. This is mere competitiveness and there is no concrete data from any service or source.
So, while there may be outliers and different situations out there, the DLI list is as uniformed and concrete as it comes:
Applicable service policies require that each candidate for the Basic Program be a high school graduate and have been administered the Defense Language Aptitude Battery (DLAB). For admission to a Basic Program, the following minimum DLAB scores are required:
• 95 for a Category I language (French, Italian, Portuguese, and Spanish)
• 100 for a Category II language (German)
• 105 for a Category III language (Hebrew, Hindi, Persian Farsi, Dari, Punjabi,
Russian, Serbian/Croatian, Tagalog, Thai, Turkish, Uzbek and Urdu)
• 110 for a Category IV language (Modern Standard Arabic, Arabic Iraqi, Chinese, Japanese, Korean, Levantine, and Pashto)
Again, this information comes straight from DLI’s main Webpage. You can check the source directly at the following Link, the pertinent information is located on page 19:
This is the student handbook of DLI. At the time of writing this article (2013), the most recent updated handbook was 2011. However, the link above is the location in which a more updated version would be placed if they were to write one.
So don’t be fouled by the blog entries of random airmen/sailors/soldiers posting what they heard someone once say. We here at DLABPrep.com found the source documents and are reporting concrete information, not guesses.
