NBBI Authorized Inspector Supervisor (B) · Work through your exam, one topic at a time.
The NBBI Authorized Inspector Supervisor (B) credential sits at the supervisory end of the National Board inspection world: it is aimed at people who direct Authorized Inspectors rather than only performing inspections themselves.

The exam is organized around four equally weighted areas. NBIC Overview covers the structure, purpose, and use of the National Board Inspection Code. Topics on this exam: NBIC Overview, NBIC 2025 Edition Changes, NBIC Interpretations, and Inspection Organizations and Data Report Registration. The NBBI Authorized Inspector Supervisor (B) study guide has 4 sections and about 1,273 words.
01NBIC Overview
Domain 1 checks whether you can place a job inside the NBIC structure rather than reaching for ASME construction rules. The NBIC is published by the National Board of Boiler and Pressure Vessel Inspectors and is organized by activity: Part 1 installation, Part 2 inspection, Part 3 repairs and alterations, and Part 4 administration. Supplements address specialized subjects. The code uses mandatory “shall” language; “should” is guidance.

The 2025 edition is a new edition of the NBIC, so the exam tests edition control as much as any single revised paragraph. Start with the foreword and revision pages to see what the committee changed, then read the changed text in its Part. Do not rely on a summary that does not identify the paragraph. A new edition can update referenced ASME BPVC editions, administrative requirements, and Part 3 repair or alteration provisions; the exact scope must be read in the 2025 text.
324 words, about 2 min03NBIC Interpretations
NBIC interpretations answer questions about the intent of existing code text. They do not create new requirements and they do not replace the code. An interpretation is tied to the edition and paragraph it addresses, so the first step is to confirm that the cited text is still the governing text. Interpretations are official National Board responses, but a verbal opinion or an informal email is not an interpretation.

The NBIC separates inspection from repair. An Authorized Inspection Agency (AIA) employs Authorized Inspectors (AIs); an Authorized Inspector Supervisor (AIS) supervises AIs and reviews their technical work. An Owner-User Inspection Organization (OUIO) is a different route for an owner to perform inspection duties within its scope. The AI does not work for the repair organization, and the supervisor’s review is not a substitute for the AI’s own signature.
