The student registration form is to be completed in full before a student can attend any class. All Students who attend a school in the District School Board of Niagara or the Niagara Catholic School Board in this current school year will have an OEN number given to them by their school and it must be on the registration form before a student can attend any class. Only students who are in a private school or will be registering into Junior or Senior Kindergarten in September may register without having an OEN number on the student form.
