What civilian certification do you have (or want) that you believe will hold the most weight when you leave service?

I am a Registered Nurse with a certification as a Critical Care Registered Nurse (CCRN). However, I am currently in grad school to become an Acute Care Nurse Practitioner. That board certification will hold the most weight for me upon retirement from the military.

Probably my nursing license and my Lean Six Sigman Black Belt

When I made the decision to leave the Army, I knew that having civilian certification would hold a lot of weight. At first I obtained my General Radiotelephone Operators License (GROL) from the Federal Communications Commission, better known as the FCC. About a year before my ETS date, I realized that I wanted to work in the marine electronics field, so I obtained my Ship Radar Endorsement, also from the FCC. I knew that I needed something more. Since commercial ships were required to have the Global Maritime Distress and Safety System (GMDSS) on board by 1999, I received GMDSS Maintainers License four months before my ETS date. A month later, I received a job offer to work as a marine electronics technician.

I advise anyone who works as an electronic technician in the military to at least get their FCC GROL license.
