Our Mission

Free, serious prep for the exams that unlock careers.

ExamsLib started with a simple observation: the people who keep our homes wired, plumbed, and built often pay the most for exam prep and get the least. We build free practice tests and study guides for licensing exams, organized by state and trade, so you can walk into test day already knowing what it feels like.

State-by-State Guidance

How We Make Content

We are not a licensing authority and our questions are study-only originals, never leaked exam content. This is the process behind every page, so you know what you are reading and how to get it corrected.

Read the guides
  • Sourced, dated, and re-checked

    Exam rules, fees, and code facts on state and license pages and in guides are checked against the official regulator, testing vendor, or standards publisher, cited on the page, and stamped with the date they were checked.

  • Written by the ExamsLib editorial team

    Articles and study material are written and maintained by our team as an organization. We do not attribute content to named experts or reviewers, and we do not claim credentials we do not hold.

  • Original practice, honest limits

    Every practice question and worked example is an original written for study. Nothing here is an official exam question, and we make no pass guarantees. Found an error? Use the contact page and we will fix it and update the revision date.
