How can I get an RN license after graduating 68C AIT? What bridge programs are most military friendly?

After you’ve met most of your requirements for the program, AECP (AMEDD enlisted commissioning program) is a great way to go. My SGT is preparing his packet for this right now - Some earn their BSN and commission via. Green to gold.

If you have your LVN/LPN license, there are some colleges that have accelerated programs to earn your RN (but I would assure you get your BSN along with it before committing and have a decent NCLEX pass rate)

See if you can get into contact with an AMEDD recruiter, they may know some tricks of the trade.

There really aren't any applicable bridge programs for a military 68C. The question has been asked on here several times. The reason there are no bridge programs is that bridge programs require you to have earned a letter grade in the course from a regionally accredited college in order to grant you credit towards your BSN. 68C does not deal with letter grades and your JSST transcripts which recommend ACE credits do not have letter grades either.
68C is not a shortcut to a BSN, as everyone else suggested, you should apply for the AECP.

Aecp. The website has all the info you need.
