This means that the student has been previously registered for an Anticipated Diploma exam or for MYP moderation through your school.

You will want to check on IBIS and ensure that the student’s IBIS personal code is updated on the Plans roster by navigating to your IBDP Year Group > Plans > Manage IBIS Personal Codes.

This will ensure that the student is identified correctly and you can then re-submit the exam subject registrations via the Register via IBIS page by clicking Register Now to the right of the student’s name.

This means that the student has already been registered for the exam period you are trying to register for. This error occurs when students are registered manually on IBIS before being registered on ManageBac. If this is the case, you will want to make all updates for that student on IBIS directly.

Failed registration attempt

Beginning with the registration for May 2022, the IBO will no longer permit exam registrations for schools with certain outstanding payments. The registrations via ManageBac in these cases will fail and the message shown below will be listed for all students. 

The ability to register candidates for this session has been withdrawn as your school has outstanding debts over 90 days old. Please contact Finance via myaccount@ibo.org for further discussion.

This error occurs when students were previously registered for MYP certified grades or Personal Project. To resolve, please enter the student’s IBIS personal code and try registering again. If that does not resolve the issue, please register via IBIS directly.

This error indicates that at least one of the selected exam subjects was added as "Additional Subject" and a blank space was left in the exam subject for registration. Subjects listed as "Additional Subject" are not included in the credits for the full Diploma.

Please make sure that 6 subjects are listed or DP1 exam scores are applied in DP2 subjects and register the students again.

These are some additional error codes that you may see on ManageBac if student information was submitted to IBIS incorrectly.
