Ha. I haven't been on here in years. Update on my situation. I did get my CSC and was promoted to Major this year. Here is how I approached it:
1. See my posts from above in 2008 for the responses I got from Army OTSG regarding CSC.
2. They also told me to go through the board of corrections. I noted the post above which advises against that because the board will simply ask the OTSG for an advisory opinion and we all know what that opinion will be.
3. I was initially denied by the board of corrections because, guess what, the OTSG advised them to deny it. I mean, what does the board think the person who denied CSC in the first place is going to say?
4. I appealed the board decision. You are allowed to do this, and I didn't care if it upset anyone. I contacted both my congressman and senator and they sent a nice letter to the OTSG and the board of corrections.
5. I also got my program director to write a letter for my appeal outlining how my master's degree adds adjunctive skills to my specialty. This is probably where some have trouble, but mine was a slam dunk.
6. The board also made a fatal error. In their decision, they said that I could not be eligible for CSC because I received my master's degree PRIOR to my medical degree. Not only is this stated nowhere in the regulations, when I sent my appeal, I highlighted the appropriate part of the regs, included the letter from my PD, and included copies of two previous board of corrections cases where they had granted CSC to applicants who had clearly received master's degrees prior to medical school.
7. Result = credit granted, time in rank adjusted, promoted in June.
Good luck. I don't see how anyone can avoid going through the Board of Corrections but I realize YMMV.
