NBBI R Endorsement study plan

NBBI R Endorsement · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

R Stamp Accreditation

  • Define the scope and limits of the R Stamp accreditation and distinguish it from other NBBI authorizations such as VR, NR, and U designations.

  • Map the accreditation application sequence from initial inquiry through joint review and final acceptance, listing the documents each step requires.

  • Identify the holder obligations that attach to the R Stamp, including the duty to maintain a Quality Control System and to notify NBBI of changes.

  • Build a one-page glossary of accreditation terms (authorized inspection agency, joint review, certificate of authorization, scope) in your own words.

Your checkpoint

A one-page process map of the R Stamp accreditation path with every required document labeled at its step.

Week 2

R Stamp Accreditation

  • Outline the criteria a joint review team evaluates when assessing an applicant's capability to perform repairs and alterations.

  • Explain how the scope of an R Stamp certificate is defined and how it can be expanded or narrowed later.

  • Summarize the renewal and periodic review cycle, including the consequences of letting accreditation lapse.

  • Draft ten self-test questions on accreditation scope and answer them without notes.

Your checkpoint

A 400-word written summary of joint review criteria plus a 10-question self-quiz with answer key.

Week 3

Repair and Alteration Requirements (NBIC)

  • Distinguish repairs from alterations using NBIC definitions, and classify ten short scenario descriptions correctly.

  • Identify which parts of the NBIC govern repairs versus alterations and locate the applicable paragraph families.

  • Explain the role of the Authorized Inspector and when an inspection is required before, during, and after the work.

  • Describe the requirements for a repair or alteration to be documented and stamped with the R symbol.

Your checkpoint

A classification worksheet of 10 scenarios with the governing NBIC paragraph cited for each.

Week 4

Repair and Alteration Requirements (NBIC)

  • Compare the documentation requirements for repairs versus alterations, including Form R-1 and Form R-2 usage.

  • Explain how rerating a pressure vessel is treated and what supporting calculations and approvals are needed.

  • Describe the rules for welding, heat treatment, and nondestructive examination when performing repairs.

  • Summarize requirements for repairs to items that were not originally stamped or that lack complete records.

Your checkpoint

A side-by-side comparison table of repair versus alteration requirements covering forms, approvals, and examinations.

Week 5

Quality Control System Requirements

  • List the required elements of a Quality Control System manual and explain the purpose of each element.

  • Describe how the QC manual is submitted, reviewed, and accepted as part of accreditation.

  • Explain the authority and independence of the individual responsible for quality control.

  • Outline how document control, revision tracking, and record retention are handled under the QC System.

Your checkpoint

An annotated outline of a QC manual with each required element and a one-line purpose statement.

Week 6

Quality Control System Requirements

  • Describe the requirements for controlling purchased items and services, including supplier evaluation.

  • Explain how nonconformities are identified, documented, dispositioned, and closed out.

  • Outline internal audit and management review expectations and how findings feed corrective action.

  • Summarize how personnel qualification and training records are maintained under the QC System.

Your checkpoint

A one-page corrective action flowchart from nonconformity identification through closure and verification.

Week 7

Inspection and Data Report Registration

  • Explain the purpose and required content of the Manufacturer's Data Report for repairs and alterations.

  • Describe how the Authorized Inspector's concurrence is recorded and what triggers rejection or return of a report.

  • Outline the registration and distribution process for completed data reports.

  • Identify common reporting errors and the QC steps that prevent them.

Your checkpoint

A completed sample Form R-1 for a hypothetical repair, checked against a 12-point accuracy checklist.

Week 8

R Stamp Accreditation & Repair and Alteration Requirements (NBIC) & Quality Control System Requirements & Inspection and Data Report Registration

  • Integrate all four domains by walking through one full repair project from accreditation authority to registered data report.

  • Re-test weak areas identified in earlier weeks with timed practice questions across all domains.

  • Memorize the key NBIC paragraph references and form numbers most likely to be tested.

  • Build a one-page exam-day reference sheet limited to items you can justify from memory.

Your checkpoint

A timed 40-question mixed-domain practice set scored at 80 percent or higher, with wrong answers reviewed and logged.

Milestones

Week 2: Can explain the full R Stamp accreditation path and joint review criteria aloud in under five minutes without notes.

Week 4: Scores at least 8 of 10 on the repair versus alteration classification worksheet with correct NBIC citations.

Week 6: Can list every required QC manual element from memory and describe its purpose in one sentence each.

Week 8: Achieves 80 percent or higher on the timed mixed-domain practice set and has a written log of every missed item.
