When applying to OCS, is there a one point waiver for an ASVAB score of 109?

GT 110 is never waiverable. Even when the Army was taking OCS candidates with only 60 SH of work, it was still a 110 GT. 110 GT is required for all commissioning programs, AMEDD, OCS, WOCS, etc. They all list GT as non waiverable.

All depends on the needs of the Army. If they are short Candidates, maybe, but I wouldn't count on it. A better choice would be to go to one of the study sites and study up on the test, then retake it and hopefully you will get a better score. I haven't heard the Army offering many waivers for OCS lately, with the exception of Age waivers.

Other thoughts: Ask about retesting, if possible, also, have you done OCS qual exams at all like AFOQT, that I had to do for USAF OTS? And, would you want grad school at all of you haven't started it yet? Look up also the intersvc PA program, if you hanpvemt seen it, run by Army at I think Ft Sam Houston, as well as the program to encourage enlisted who want medicine, it's intersvc also, I've seem YouTube videos on it, also, look up http://www.usuhs.edu, esp the USUHS grad school PhD programs, which can also be done as a civilian, I realize you're active duty now, I'm just explaining, also their grad school for nurses, up to doctoral level, though I realize that might not be your interest, as I'd said, elaborate in detail, I'll try to suggest other possibilities, if I can, OK?
