Hello, Thanks for using our Ask and Answer section. I found some links to downloadable example forms from ICMA in regards to manager performance evaluations. https://icma.org/documents/sample-manager-performance-evaluation
Additionally I found an article about overall ways to improve your organiations performance review process if that is an area you are interested in.
Feel free to search Manager Evaluation on the ICMA page, you will find a handful of other great examples.
