We also have a 3 tiered system - Does Not Meet, Achieves and Exceeds, with Exceeds being the person who walks on water (if you catch my drift).



I also just had a review.  Wouldn't you know it, after typing hundreds of letters and other documents over the past year, boss writes in the review a comment about the one letter I royally goofed up three days before the review (I don't know what I was drinking that day) and had to retype.  



Reviews are good though, keeps me on track, but it's the nit-picky stuff that they drag out that is most frustrating.  



It would also be nice if the boss would explain what competencies they want us to achieve, not for us to second guess them.  They need to back us up when we try to achieve this competency.  For example, they want us to show leadership.  However, in order to do that, they need to ALLOW us to show leadership.  Or if they want us to be a better team player, include us on the team from the beginning to the end of the project.
