http://www.uscg.mil/psc/epm/docs/A-...olList.pdf The estimated wait time says 18-24 months. I would venture to say that it will be more towards 24 months. You are eligible to put your name on the A-School list after you have been at your unit for 4 months. Some units also make you be fully qualified before they sign your chit, so in some cases it might be a little while longer.
