If your Academy Admin has enabled self-assessments for you, then through them you will be able to evaluate yourself both in your required metrics and the available Academy Metrics. The Perception Gap will then help you better understand the gap between how you evaluate yourself on certain metrics and how differently you were assessed by your managers.

Once both you and your manager have provided an assessment, the perception gap dashboard will help you investigate the gap in the perception between you and your managers. You can access your Personal Perception Gap Dashboard if you hover over Me, click My Dashboard, and then select Perception Gap.
Zero gap means that both your manager and you agree completely on your performance. A negative perception gap means your manager has assessed you more austere than you yourself and positive means the opposite.
