1–12. Access to evaluation reports
a. Access to Army evaluation reports at HQDA is limited to the rating officials on the evaluation report, the rated Soldier, the BN/BDE S1 or administrative office servicing the unit responsible for preparing and processing the evaluation report, and/or those authorized to use evaluation reports for personnel management purposes. Requests to access evaluation reports prepared by another unit or rating chain officials cannot be granted.

Don't know if it is still done, but it was once common for a previous CO to write a Letter of Continuity to the receiving CO concerning the transferred officer's strengths, weaknesses, or concerns. Was often advantageous to the transferred officer, i.e. good officer but has spouse or child suffering from **** which should be considered in assignment.
