Can I Retake The DLAB?
Someone failing the test or getting a low score can always retake the DLAB but only after a wait of 6 months. For most service members, this is too long and will cause them to miss the deadline for submitting their scores.
If you do not pass the test or you received a low score, you can always retake the DLAB but will have to wait another 6 months before doing so.
