What are my best chances to get promoted to SSG?

Several people have already offered you some great advice on what to do personally to enhance your chances of getting promoted. I would offer as a reminder that we are in a shrinking force right now. Sequestration is still on going and cuts to authorizations are still being implemented. Don't take it personal that you are not being selected, many good NCOs are not getting picked and some senior NCOs are being sent home because we (army) just don't have enough slots to fill anymore (thanks to congress and POTUS). But let's focus on the positive, you are still in and still competing. Keep doing great things and your hard work will eventually be recognized.

Your best chance at getting promoted is being the best SGT and TL you can be. How are you ranked on your NCOER against the other TL in your platoon? I know when I retired every E-5 in my platoon was ranked from top to bottom, and guess what if you weren't in the top 50% you got the counseling telling you that you weren't going to be recommended for promotion. You got to constantly be learning, and demonstrating you have the ability to be recommended; however, you can't be consumed with making yourself look good. No one likes the guy who get's every school, and only thinks about advancing himself and not bettering the Army.

Hope our points drop from being maxed. And when they are do, you have enough. Check your 3355 for what areas you are lacking in and work on those areas. As for positions, work hard and take on additional duties.
