Plumbing Journeyman Study Center.
Practice across five plumbing-code subject areas with spaced repetition. Each track surfaces questions when they're due — answer Again, Good, or Easy and the SM-2 ladder schedules the next review. Coverage spans both model codes: the IPC (International Plumbing Code, ICC) and the UPC (Uniform Plumbing Code, IAPMO). Where the two diverge, the question notes which family it applies to.

Questions are paraphrased from publicly-available IPC/UPC summaries and study material — the model codes are copyrighted, so canonical wording and the in-force edition must be confirmed with your AHJ. State amendments (e.g., the California Plumbing Code) may override model values. The proctored journeyman exam is administered by state licensing boards and is the only path to licensure.
