Parents are instructed to send an email to registrar@anconaschool.org with changes of address, email, phone numbers, etc. If you as a teacher receive such a message, you may forward it to this address, which goes both to the front desk and tech staff.
The front desk staff periodically puts up signs asking for parents to update their contact information. In addition, the information on file is displayed to parents as they sign their electronic contracts, and they are asked to confirm that it is correct.
