**This represents a significant savings for schools that previously paid a flat fee plus a per student fee. It is simple and predictable, enabling you to more easily budget for this small expense. Please tick off in which category you school falls. We may have sent you an email to invite you to join. (In case we have assessed that your school falls into category [1/2/3/4] we have attached an invoice for [$150/$300/$500/$650].) Please alert us by responding to this email if we have incorrectly categorised your school and we will resend an invoice for the correct amount.
