Appraisals in the workplace are not supposed to be written like school reports to be read by parents!
I physically cringe when I see a professional, grown-up appraisal written in the third person, like this:

The appraisal is meant to stimulate a conversation between you and Dave, not to be read by Dave's Mum or Dad! It's not meant to be written for HR either; performance and results are owned by line management (yes, that's you now!), not anyone else. Please write in the first person!
"You have met or exceeded all of your targets this year…"
