If you don't already have a Schoolrunner account, you can create one with an access code (or codes) from your school, which allows you to see data related to your student(s). Once you've used an access code to make an account, you'll be able to log in without needing that code anymore.
The Schoolrunner mobile app is only accessible to parents and guardians whose school already uses Schoolrunner. If your school doesn't use Schoolrunner, you are not able to sign up or log in on your own.
You must first enter your school's "domain". This is generally the last part of the school email address (i.e. the "dpsk12" in email@example.com, or "collegeprepacademy" in firstname.lastname@example.org). If you're not sure what your school's domain is, ask a staff member.
Then, tap "Parent/Guardian Sign Up" if you don't already have an account. Make sure to sign up with a working email address that you have access to, or else you won't be able to reset your password if you forget it.
If you already have an account, tap "Sign In With Password" to log in (or, if you signed up with a Google email address, you can just tap the Sign In With Google button).
You must have at least one student access code to be able to create an account with Schoolrunner, but can add more to your account if you are the guardian of more than one student and the school has provided you with access codes for each of them. Tap on the "Add Student" icon in the top right corner to enter another student's access code.
