Should I send an update to the school?
I have been promoted this week at my company. In fact the promotion came 3 years early than usual time based on my performance and leadership ability. Have been assigned more responsibility and a team that reports me now has increased from 30 to 65+.
YOU MUST.
You see, it is a great achievement. So, I am sure, the AdCom would see it that way.
Put it in a way that you got that promotion for your work ethics and qualities. At the same time don't brag. And add the fact that you are still interested in joining Rice, as you were when you applied and intend to join.
Unless you have any other school as your priority, I would say, let them know.
