Register to Take a National Board Exam

The National Board has partnered with Prometric to administer examinations. Examinations will be rolled out on the new Prometric platforms over the next few months.

Not all exams will be immediately available on Prometric -- the AI and IS commission exams will remain available at PSI/AMP locations until transitioned to Prometric.

Currently, only the following endorsement exams are available at Prometric:

Authorized Inspector Supervisor (B) exam
Authorized Nuclear Inspector (N) exam
Authorized Nuclear Inspector Supervisor (NS) exam
Repair Inspector (R) exam

The remaining endorsement exams (C, I, NS, and O) will be made available as soon as possible. They are currently in various stages of development. This page will be updated as each exam becomes available.

The Process

The exam candidate must first complete the associated National Board training course.
The exam candidate submits their legal name, exam requested, and exam fee to the National Board Training Department by clicking the exam name from the catalog below then completing and submitting the registration form.
The National Board notifies Prometric of an exam candidate's eligibility.
Prometric emails the candidate to schedule the exam on the candidate's requested date and available Prometric location.
Exam results are provided to the exam candidate at the end of the endorsement exam.
Upon receipt of exam results, the Training Department will update the candidate's records.
Exam results are sent to the Training Department.
The National Board will email exam results to students upon receipt from Prometric.
