To schedule an appraisal for your staff member, navigate to the Appraisals tab via the left hand navigation bar and scroll to the bottom of the page. Here, you will find all past appraisals for all users. 

NB: Admins will see appraisals for all employees. Line managers will only see these for their reports. Staff will need to navigate to the Appraisals tab on their profile to see their own appraisals.
