These figures are web-verified for 2026 but change and vary by cycle and classification. Always confirm current requirements and fees with your city or county building department (general contractors); Colorado DORA licenses the electrical and plumbing trades before you apply.

What the contractor exam usually covers
Most state contractor exams include a Business & Law section (contracts, licensing and lien law, employment and safety rules, and financial/estimating basics) plus one or more trade/technical sections tied to your classification (general building, residential, electrical, plumbing, mechanical, and others). Many states deliver these through third-party providers such as PSI or Prometric, and exams are frequently open-book with an approved reference list. Passing scores are commonly around 70–75%. Always verify the exact classifications, exam sections, allowed references, fees, and passing score with your state contractor board before you apply.
