Before you apply

  • Age: at least 18.
  • Training and test: the RMI, an owner or a manager of the business, completes 16 hours of pre-license training and passes the exam. If you passed the NASCLA commercial exam, you skip the training but still take the Oregon exam.
  • Experience: one or more key employees must have a combined 8 years of construction experience for Level 1, or 4 years for Level 2.
  • Experience substitutions: an apprenticeship or a construction-related bachelor’s degree can replace up to 3 years. A business, finance or economics degree can replace up to 2 years, and a construction associate degree up to 1.
  • Bond and insurance: Level 1 needs an $80,000 commercial bond and $2 million aggregate liability insurance. Level 2 needs a $25,000 bond and $1 million aggregate.
  • Workers’ comp: commercial contractors must carry workers’ comp, including “personal election” coverage if they have no employees.

Step by step

  1. Pick Level 1 or Level 2Both levels do the same work. Level 1 needs more experience, a bigger bond and more insurance. Choose the one your key employees’ experience supports.
  2. Take the 16-hour trainingSign up with a CCB-approved provider. When you finish, the provider sends your information to PSI so you can schedule.
  3. Schedule and pass the examPay PSI $60 and test at a center or by remote proctor. Bring your own NASCLA Oregon manual. If you fail, you can retest with no limit.
  4. Set up the businessRegister the business and name with the Secretary of State. The bond and insurance must be in that exact name.
  5. Get bond, insurance and workers’ compBuy the commercial bond and liability coverage for your level, plus workers’ comp.
  6. Apply within 24 monthsSubmit the CCB application with the bond, insurance certificate, test score report and the $400 fee (two-year license).

The reference books

The exam is open book, with one approved reference: the NASCLA Contractors Guide to Business, Law and Project Management, Oregon Construction Contractors, 2nd edition. English and Spanish versions are available, and you may bring both.

You bring your own copy. You can highlight, underline, tab (removable or permanent tabs) and index it, and handwritten notes are allowed. You can’t write in it during the exam or bring loose papers.

What’s on it: Oregon contractor laws and regulations carry the most weight (18 items), then contracts (9), hiring and managing employees (7) and bidding and estimating (6). Lien law and scheduling and project management have 5 items each. The rest are 2 to 4 items each: business structure, subcontractors, building codes, jobsite safety, environmental factors, building exterior shell, financial management and tax basics.

If English is your second language, you may bring one bound, word-for-word translation dictionary with an ISBN and no writing or tabs.

  • Answer what you know first, then look up the rest. You have about 2¼ minutes per question.

Quick answers

What’s the difference between Level 1 and Level 2?

Both can do the same commercial work. Level 1 needs 8 years of key employee experience, an $80,000 bond and $2 million aggregate insurance. Level 2 needs 4 years, a $25,000 bond and $1 million aggregate. Continuing education also differs.

Is there a trade exam in Oregon?

No. The Oregon exam covers laws, rules and business practices only. Your experience is shown through your key employees.

I passed the NASCLA commercial exam. What do I skip?

You skip the 16-hour pre-license training. You still have to pass the Oregon exam. Send proof of your NASCLA pass to the CCB so it can make you eligible with PSI.

Do I need a residential endorsement too?

Only if you’ll work on residential structures. Commercial endorsements cover small and large commercial structures. If you hold both, you need two bonds and one liability policy at the higher amount.

How much continuing education will I need?

Level 2 needs 32 hours each two-year cycle, completed by key employees. Level 1 depends on your number of key employees, from 16 hours for one up to 80 hours for five or more.
