In the advanced settings of your assessment set up, you will see an option to Enable Eval Strength Criterion Factor. Selecting this option allows you to scale back less valuable subjective criteria. Once this feature is enabled, all subjective criteria will include a Strength Factor bar when in the edit mode.
To make a criterion less valuable, move the circle to the left. The new weight of this criterion will be listed on to the right of the bar. Click "Save" when you are satisfied with the adjustment.
Note that this is an advanced feature and it's generally best to only use Evaluation Criterion Strength Factor when it's suggested by a TeamGenius Customer Success team member.
