According to National Petroleum Management Corporation, “The candidate must achieve a passing score of at least 75 percent on the exam.”[1]
The Certified Petroleum Apprentice is the entry level of the NPMC certification ladder. It shows that you know the basics of petroleum work: fuel properties, hardware, pipeline systems, fuel quality, safety and environmental practice.
Eligibility. The NPMC Certification Handbook lists these requirements for Level 1: pass the certification test, be fully qualified in your current job, and have at least 6 months of petroleum experience.
The test. When you are ready, NPMC gives you a proctored, 100-question test. You need at least 75 percent to pass. The test costs $927 USD each time you take it. NPMC also offers free online study modules. Start with those, because they come from the body that writes the test.
Validity and renewal. Your certification is valid for 3 years. To renew, you pay a $50 USD recertification fee and send in an updated education, training and experience worksheet. NPMC then renews or upgrades your certification based on that worksheet. You do not take another test.
What we could not verify. We do not have confirmed details on retake rules, retake fees, time limits, scheduling or test locations. Check these with NPMC at npmacertification.org, or in the NPMC Certification Handbook, before you pay the fee.

Prepare for the CPA - Certified Petroleum Apprentice exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: During a petroleum spill on a concrete surface, the spilled material should be absorbed using:
Answer: B. Dry absorbent materials such as sand or spill-kit pads
Explanation:
Correct: B, dry absorbent materials such as sand or spill-kit pads. Dry absorbents soak up petroleum where it sits. The spill stays in one place and can be bagged and disposed of properly.
Rule to remember: contain the spill, do not spread it. Use dry absorbents, keep ignition sources away and keep fuel out of drains.
Question: Why is it important to inspect drilling equipment regularly?
Answer: B. To ensure early detection of faults and prevent accidents
Explanation:
Correct: B, to detect faults early and prevent accidents. The main reason for regular inspection is safety. Finding wear, leaks or damage early means you can repair or replace parts before they fail and hurt someone or harm the environment.
Rule to remember: when a question asks why a routine check or procedure exists, the answer is usually about preventing harm to people, equipment or the environment. Cost and speed are side benefits.
Question: What is the primary purpose of using a taper comb during a haircut?
Answer: A. To create a smooth gradient blend between lengths
Explanation:
Correct: A, to create a smooth gradient blend between lengths. A taper comb has teeth that change in spacing along its length, so the barber can lift hair at different heights and cut a gradual change from short to longer hair.
Rule to remember: match each tool to the job it was designed for. Note that this question comes from a barbering set, not from the NPMC content areas, so it will not appear on the petroleum test. Spend your study time on the sets mapped in the table above.
Start with the official material. Work through the free NPMC online study modules before anything else. They come from the body that writes the test, so they set the scope. Keep a short list of terms and procedures you find unclear.
Practise by content area. Use the table above to match each official area to a practice set. Some sets on this page cover topics outside the NPMC outline. Spend your time on the mapped sets first. For Quality, which has no matching set here, rely on the NPMC modules.
Review every miss. After each set, read the explanation for every question you got wrong. Then write down the rule behind it in your own words, such as "contain a spill, never spread it". Go back to the matching NPMC module for any area where you keep missing questions.
Simulate the real test. Once each area feels solid, use the Start Practice Test link for a mixed run. Aim to score well above the 75 percent passing mark, so a few hard questions on the day do not decide your result.
Before you book. The test costs $927, so confirm the scheduling, proctoring and retake details with NPMC first.
The test has 100 questions and is proctored by NPMC. You need at least 75 percent to pass. We have no verified time limit or retake policy, so check those with NPMC or in the NPMC Certification Handbook before test day.
NPMC charges $927 USD per certification test. The study modules on the NPMC site are free. Renewing later costs $50 USD and does not involve another test. The fee is charged per test, so confirm any retake costs with NPMC before you book.
According to the NPMC Certification Handbook, you must pass the certification test, be fully qualified in your current job and have at least 6 months of petroleum experience. If you are unsure whether your experience counts, contact NPMC before paying the test fee.
The certification is valid for 3 years. To renew, you pay a $50 USD recertification fee and send in an updated education, training and experience worksheet. NPMC uses that worksheet to renew or upgrade your certification. You do not take another certification test.
No. We wrote these practice questions ourselves, using AI tools. They are not taken from the NPMC test. They are meant to help you practise the official content areas and spot weak areas. Treat the free NPMC study modules as the authority on what the test covers.
