For goal-based reviews or the numerical questions in evaluation forms, you can set up a single global rating scale from the Performance tab within Settings / Configurations.
When editing the global rating scale, you can choose anything from a 3-point scale scale to a 10-point scale, and you can also edit the labels and descriptions to match your organization’s requirements.
If you want to give evaluators the option to mark N/A to certain goals or numerical questions, you can also switch on the toggle corresponding to this. Please note. if an evaluator selects N/A for a goal or a numerical question, this question would not contribute to any overall score calculation.
