Getting Started
How do you choose the right Navy rate for you?
Choosing a Navy rate means weighing your ASVAB scores, lifestyle preferences, civilian career goals, and willingness to deploy or go to sea. Start by identifying which ratings you qualify for, then narrow the list by what matters most to you.
Getting Started
What is the ASVAB and what scores do you need?
The ASVAB is a multi-aptitude test that determines which Navy ratings you qualify for. Your sub-test scores combine into line scores, and each rating has minimum line-score requirements. Higher scores open more options.
