What effect does making commandants list on a 1059 have for promotions in the senior ranks?

Great question. I made the Commandant List at all 3 NCOES. If you look at previous promotion boards AARs it will state in most of them that individuals that exceeded the standards at NCOES courses were looked favorably, why? Let's make it simple, we have 1 position to fulfill and 2 packets remaining, yours and a peer. Both packets look alike, both 1/1 on NCOERS or best qualified if under the new system, both have the same schools and on and on. Here's where a "positive" discrimator which is the same as setting yourself apart from your peers comes into effect. If both packets are the same and both have APFT scores of 300, then look for something else that one packet has and the other don't. If you have a check mark on "exceeded course standards" on your 1059 and the other guy don't, then is like sorry you're both great NCOs but only one promotion. The answer is we will promote the one that had the one positive discriminator. That's why is so important NOT to take anything we do in the Army lightly and always try to exceed standards in everything we do. Apply the analogy to pro-football, if I have one player scoring 2 touchdowns per game and one scoring 1 or less during the pre-season, who will I select to be on the team and that's saying they are getting the ball thrown to the same number of times.

It is a feather in your cap, as it distinguishes you from your peers by using a universally accepted standard, but it is not a panacea. Other elements of your packet are scrutinized more and weighted more by board members.

I can't answer that, never got one, made SFC at 9 years of services , many of my peers than got it make SFC at 12 or 13 years, I think performent in an NCOER weight more than a 1059 that is my opinion
