Evaluation templates have their own options enabling more security in the appraisal process. One such feature is the option to "Allow appraisers to lock the instrument so that only the appraiser, staff member being evaluated and district viewers may view the evaluation content.". Only if this option is selected for the template will appraisers have the View Locked or View Unlocked buttons on their menu bar.
When you ready to complete the evaluation form, click the View is Unlocked button on the menu bar to lock the form.
This will change the button to show that the View is Locked.
When the View is locked, no one else can see the evaluation contents EXCEPT the Appraiser and Appraisee.
