Tennessee CMC-A Mechanical Plumbing
Tennessee moved its contractor exams from PSI to Prov on July 1, 2026. This practice test still follows the PSI exam outline. It covers the same subject areas, and the PSI-approved books our questions cite are allowed in Prov's test room through January 1, 2027, so it's fine to study with. We're updating it to Prov's new outline, and the update will show up in your account automatically.
