The three states
Redeeming a code is the only way through
A teacher enters the signup code issued to their school. If the code is recognised, active and unexpired, the account activates immediately and joins that school’s cohort. There is no approval queue, no waiting on a decision from MESO, and no button an administrator presses to let someone in. Issuing the code is the approval. That is why generating and sharing codes is the first thing to sort out in a rollout — see Inviting members.When a code is refused
A teacher will see one of three messages, and each has a different fix:That code was not recognised
That code was not recognised
The code does not exist. Almost always a typo, or an old code from a
different school. Check the exact string and reissue if needed.
That code has been deactivated
That code has been deactivated
The code exists but has been switched off in Settings → Workspace →
Members. Reactivate it there, or issue a new one.
That code has expired
That code has expired
The code is past its expiry date. Expiry is per code, so generate a fresh
one — teachers who already redeemed the old code are unaffected.
