Skills That Transfer
Recommended Certifications
These certifications can increase your salary by 10-25% and make you more competitive for civilian roles.
How to pay for these — you likely don't pay out of pocket
- GI Bill: the Post-9/11 GI Bill reimburses licensing & certification test fees up to $2,000 per exam— and it doesn't use a full month of entitlement.
- While you're still in:your branch's Credentialing Assistance program can cover the full cost of many of these certs (often several thousand dollars a year) — check Marine Corps COOL ↗ for what's funded and current amounts.
- Tip: start certs before you separate — Credentialing Assistance is only for currently-serving members; after separation you shift to the GI Bill.
