It is not a punitive process. The appraisal process should be a positive and helpful experience for the volunteer. Allow the volunteer to participate by offering an opportunity for self-evaluation. Ask what areas they would like to improve, or special topics they could learn more about. Include the volunteer's goals, along with the supervisor's goals, in the performance appraisal.
Performance appraisals can also serve a variety of other functions.
They can be excellent opportunities to solicit feedback on supervision. To develop a volunteer performance evaluation form, begin with the position description and rate the volunteer's performance in each area. Then proceed to the volunteer's individual goals, and determine jointly with the volunteer whether those goals were met completely, in part, or not at all. If the volunteer falls short of the goals, explain why. Next, review the volunteer's self-appraisal, and discuss any areas of concern.
