Admins can allow admin visibility into in-progress reviewer responses alongside completed ones.
Navigate to Admin > Performance > Performance reviews.
Select the performance review.
Under Calibrate ratings > Calibration groups, select the ellipses (...) in the top right of the page and check Show in-progress review scores.
Once toggled on, drafted scores will appear in the Calibration table. Hovering over the score will show that score has not yet been submitted with the message 'Draft - this reviewer has not submitted their score'.
You can switch the feature on and off whilst the cycle is active; once you have ended the writing phase and started calibrations, it cannot be enabled or disabled.
