Allow Teachers to Pre-Book Appointments

The default Administrative access for teachers is Appointment Viewer access only. You can, however, provide all your teachers with Appointment Maker access. This would then allow your teachers to book appointments on behalf of parents prior to opening up the scheduler to parents. 
 To modify the teacher access, you would go to the Global Setup / Contacts   page,  Advanced Options section, and click on the  Modify Access Level button. Modify your teachers' access from Appointment Viewer to Appointment Maker. 
 Each teacher will only have access to their own schedule.
