one of the most annoying things to me are managers who pull the "here's what I'm evaluating you on...now write up this self eval what you've done over the last year that fits these items and I'll copy paste it into your eval." Why even become a manager if you can't capture these yourself? A self evaluation should be a reflection of what a person gained over the past year and not an exercise to fill out a form for a manager to remind them of such.

As a manager I take notes throughout the year WITH my staff to capture what they worked on, how they grew, and all that stuff. If there are stumbles along the way we capture those too. It just makes it easier to then show the higher ups how consistently good a person is (or not in some cases). The self eval is less of an exercise in futility of reminding the boss what you did but an opportunity for staff to reflect on their growth.
