Can I delete pending evaluations?

Yes, please visit Evaluation records > Use the Delete icon to delete the pending evaluations.

For example, Hailey Brown is the person whose evaluation is pending but not required in the software. You can then visit Evaluation records, search for Hailey Brown using filters and then delete her evaluation by clicking the Delete icon on the right.
You can also filter the pending evaluations by using status filter then select Pending.
