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.
Some districts provide direct links to access the registration forms while others use the PowerSchool Parent Portal for the registration process. The link and access credentials are generated and provided by the school.
I recommend contacting your student's school directly to request the instructions to access your student's enrollment forms. You can check out the FAQs related to the enrollment process here.
Snapcodes are student-specific identifying codes that add an extra layer of security to your student’s information. If you have not received your Snapcode or are not able to access it, we would recommend that you contact your school district’s Enrollment section directly to receive your Snapcode.
I have attached an article here that should guide you through a few steps you can take before contacting your school.
