   Students can make appointments online using Teach Assist:


 ·   Have your child log in to their Teach Assist account

·   Under the sub-heading “Appointment Bookings” 

·   Click on the day and time the student wants to have their appointment  (if the appointment slot is  

     highlighted in blue). If there are no appointments displayed, then you will have to select another 

     day, as all counsellors have been booked for that day. 

·   You will see shaded in blue “All open appointments”. Choose the appropriate alpha Guidance 

     counsellor (based on your child’s last name) from the list on the left.

·   If the student needs to cancel their appointment for any reason, click “cancel”.

If your child has any trouble making their online appointment, please let us know.
