Yes. Signing your appraisal form indicates that you have reviewed the appraisal form and discussed it with your supervisor not that you agree or accept it. If you disagree with your rating, the first thing you do is discuss the matter with your appraiser (supervisor). Explain your objections clearly and provide evidence to support your position. If you and your appraiser are unable to reach an agreement you should inform the Department of Human Resources of your objections. You can do this by making a note on your objections under the Employee Comments section of the appraisal form. The matter will then be reviewed by the Performance Management Unit.
