In the educational centre, open Guardians and click Create guardian. Fill in Name, Email, Calendar year and Course, then click Create. They receive an email invitation with a link to create their account. Until they accept it, they show as Unregistered.
This course is not set up for the selected year means that course has not been assigned to the calendar year you picked. Go to Calendars, open the year with View Courses, and use Assign Subject to set it up. Then return to Create guardian.
They show where each guardian is in the process:
If someone stays Unregistered for a long time, the likeliest reason is that they have not opened the invitation email.
Open the invitation link on your phone and tap Create account. You will see Accepting invitation... then Invitation accepted. When Your account is ready appears, tap Get started. You will then Choose your language and, if your account does not have a name yet, set What should we call you? — that is the name other parents and teachers will see. Both can be changed later in Settings.
The language screen appears in your phone's language: choosing Español does not change the text until you confirm with OK.
✅ Verified on a device, 2026-09-01. Language is the first step. The name step did not appear for an account that already had a name, so it is conditional. Screenshots:

The link is single-use, but it does not expire: an invitation from months ago still works, as long as you have not accepted it yet. So this message almost never means you missed a deadline.
Most often it means you have already accepted it, or you are opening the link while signed in as a different account from the one invited. Tap Try again in case it was a momentary glitch, and if it persists, contact your administrator. It is not something you can fix from the app.
The invitation is tied to the exact email it was sent to. If you signed in with a different one — a separate personal account, say — you will see This invitation link doesn't belong to your account. Sign out and sign back in with the email the invitation was sent to. If you are not sure which that is, check which address received the message.
Your account already exists — most likely you used the invitation before. There is no need to create it again: tap Sign in and use Continue with Google with your usual email.
Both are in Settings. Your name is what other parents and teachers see, so it is worth making it recognisable. If you skipped these steps at sign-up with Skip, you can set them there at any time.
