Is it authorized to rate somebody the same rank as you for an OER?

As an HHC commander, when I PCS'd I had to rate my XO, who had been promoted to O3 about two months prior. But, as you can see, I was in his chain of command and for the qualifying amount of time. If this captain is on staff, he/she should be rated by the S3 or Bn XO. If an acting S3 or Bn XO has not been in the rating chain long enough to qualify as the eater, then the senior rater does the whole OER themselves without any rater comments, other than "per AR-xx, the current rater is does not qualify to rate this service member." - keep in mind, the rated officer's previous rater should have initiated a change of rater OER prior to their departure, unless that officer was relieved for cause.
Any CSM, 1SG, AG officer, or HR expert - please correct my mistakes as its been a while since I went through this situation. Thx - Mo

No....you can not rate a officer that is not in your chain. Its like rating a CPT that is a pilot and you are a MI officer. Now if you are the supervisor that was responsible for him/her different story. But your Bn Cdr is wrong, but most likely because he has a certain amount of Captains on his profile he can rate, he's trying to shortcut a situation, but he cant do that. AR623-3 is the regulation that covers this.

Are either of you special branch officers? (Chaplain, JAG, Medical ...) Aside from whether you are in the supervisory chain, the reg (and law) says the rater must be senior in grade to the rated officer. The exception is those in positions deemed to be senior - i.e., Commanders can rate anybody else in their unit. The clause that goes with the evaluation is "By Direction of the President" I was a group S-1 and our Group Chaplain (a Catholic priest, and an O6) had about twenty years TIG over the Group Commander (a QM O6) but, because the commander was in the command position, he could rate officers of the same grade and actually senior to him by TIG. I don't think anybody at HRC checks, but if there is an appeal, this is a gimme at the Board.

Sure...you see it at the O6 level without an issue, folks not on a track... but it doesnt pass the common sense drill IMO to be done at the CGO level...

I don't know your Bn CDR's intent but it might be agreeable for the rated officer to have you as his intermediate rater, that way you retain your authority without the officer having anxiety that he/she is being disadvantaged on his OER real or percieved.

You are authorized to rate another CPT if in fact you are his direct supervisor and at least for 90 days. For example, you are the company commander in a medical unit and you have nurses that are CPTs and work for you. They would answer to you since you are in command. However you also have to be in rater scheme that should have been published monthly and signed by your BN CDR. You cant just be made the rater overnight.

AR 623-3 is the OER system (if I remmeber Correctly)

He obviously values your input. Maybe he cares about "peer" views.
He asked, I would do it. He knows tha parameters of what you are and are not exposed re: this other 0-3.
There is nothing in any manual that forbids who gives him input.

Hello CPT Hignight,
As I understand it you need to be one rank above another to be the Rater. The Only time rank does not matter is with a Physician Assistant(PA) who require a Physician as Rater or Senior Rater. Then the Rater who is MD and CPT can rate A PA who could be a MAJ. The Senior rater needs to be one up from Rater or in Command Position. You can check with your Higher headquaters and your Unit might need a letter of accepatnce to allow you to be a Rater ( when the Unit has limited Officers)

Hope this helps,
MAJ(P) Mickey

Rating officers of the same grade is not that uncommon; however positional authority as a supervisor over the other officer(s) has always been present in my experience.
