I was able to complete the returning student registration for my daughter, however when i tried to do the same for my son, I received the following error message:
Sign in Problem
There was a problem with the sign in process.
Please contact your school or the Support Team for assistance.
The PowerSchool Community is a great resource if you have any changes to be made while completing fields within the enrollment form. Each district, however, has a different registration process and can provide the best steps to move forward when enrolling students.
I suggest you reach out to the district directly to inquire about this because they will be able to assist you with gaining access to your son's registration.
You can check out the FAQs related to the enrollment process here.
