Name conditions when a trainee could not work in a dental office.

3 exam failures

Failure to complete exam in 12 months from employment

Trainee status has expired and not registered

All of the above

In Iowa, a trainee is allowed to work under supervision only while they meet specific licensing and registration requirements. Each of these situations alone stops that eligibility: failing three exams indicates the credentialing path isn’t being completed successfully; not finishing the required exam within 12 months from employment halts the progression toward licensure and can void the trainee status; and having trainee status expire without re-registration leaves no valid status to authorize any practice. Since any one of these scenarios prevents lawful work, the combination that includes all of them is the correct choice.
