The Chilliwack School District has moved to a centralized, electronic registration system. Our schools no longer accept paper registration forms. This online process provides parents and guardians an option to register their child at any time, even over the summer break. This includes registration for K - 12, French Immersion and out of catchment requests. You will be required to:
1.      Provide a valid email address
2.      Upload a copy of the child’s birth certificate
3.      Upload proof of residency
Once you have registered online, you will be contacted by the school to notify you if your registration is accepted and/or to setup an intake meeting.   Our school is closed during the summer so this may not occur until the last week of August or first week of September.
