Will the timing of an incomplete change of rater NCOER (to take a higher position within the Bn) impact my promotion chances?

SSG (Join to see) In my opinion, it won't hurt as long as its within career progression and if you worked as a E-7 it can do nothing but help. Do a COMPLETE THE RECORD NCOER in your new position. This will improve your chances for promotion, especially in a higher HQ and position. Good Luck!

If you have a new duty position, THAT YOU HAVE NEVER BEEN RATED FOR, you can receive a Complete the Record NCOER. I never received and NCOER rating me for a duty position higher than my pay grade, so I personally don't think it is as big a deal as some people think. If your records are complete. You have a current DA Photo (you would be surprised how many don't do ti). Your ERB is up to date and IN ORDER (ensure all past units and duty positions mirror your NCOERs). Your NCOERs are all 1/1s, you have nothing else you can do but pray because it is in the Promotion Board's hands. They look for different things on each board. You won't know what they are concentrating on until they release the board results.

Read the Milper message about the board it gives some guidance... I hope that helps
