What to Bring to the CSLB Contractor Exam: Checklist

Bring a government-issued photo ID and get to the test center 30 minutes before your scheduled time. (CSLB Get Licensed to Build, p. 24) Those are the only two instructions CSLB's guide gives on what to bring. You do not bring books or notes, because the exams are closed book, and you do not bring a calculator, because one is provided when the exam has math. (CSLB Study Guide B) This checklist is built only from CSLB's Get Licensed to Build and its study guides as printed in the editions we reviewed. Procedures change, so confirm current details with CSLB and with the instructions that come with your exam notice.

Photo ID that gets you through the door

The guide names six kinds of government-issued photo ID that are accepted for admission to the test center: (CSLB Get Licensed to Build, p. 24)

• a current, valid driver license
• a Department of Motor Vehicles identification card
• a U.S. passport
• a military identification card
• a Resident Alien Card issued by U.S. Citizenship and Immigration Services
• an Employment Authorization Card issued in the United States

The testing vendor, PSI Exams, mails each applicant a Candidate Information Bulletin. According to the guide, it covers the exam locations, directions and the required identification. (CSLB Get Licensed to Build, p. 23) Read it a week ahead rather than the night before, so a missing or expired card is a phone call and not a lost appointment.

Arrive 30 minutes early: a worked example

The guide says to be at the PSI center 30 minutes before the scheduled exam time. (CSLB Get Licensed to Build, p. 24) If your appointment is at 1:00 p.m., plan to walk in at 12:30. If you booked an evening slot at 5:30 p.m., that means 5:00. Test centers operate Monday through Saturday and include evening hours, so you have room to pick a time that fits your work week. (CSLB Get Licensed to Build, p. 23)

Do not treat the 30 minutes as optional. Someone who arrives late may be refused entry and may forfeit the exam registration fee. (CSLB Get Licensed to Build, p. 25) If something comes up beforehand, you can cancel and reschedule without losing your fee as long as CSLB receives notice two days before the exam date. (CSLB Get Licensed to Build, p. 25)

What not to bring: books, notes and a calculator

The Law and Business study guide states that the exam is closed book and that no reference materials may be used. (CSLB Study Guide LAW) The General Building (B), Plumbing (C-36) and Electrical (C-10) guides say the same thing about their trade exams. (CSLB Study Guide B) (CSLB Study Guide C-36) (CSLB Study Guide C-10)

The reference books listed at the end of each guide are for studying, not for the exam room. CSLB describes the guide as listing the topic areas, sample questions, how each content area is weighted and recommended study materials. (CSLB Get Licensed to Build, p. 24)

For math, the guides say some questions require computation and that a calculator will be provided. (CSLB Study Guide C-10) So practice with a plain calculator, the kind you could use for a bid, and do not count on a favorite model with stored formulas. The sources reviewed here do not describe any other items PSI may or may not allow in the room, so rely on the Candidate Information Bulletin for anything else.

Exam security rules that affect what you carry out

CSLB lists conduct that violates exam security. The items that matter on the day are these: (CSLB Get Licensed to Build, p. 26)

• Taking exam materials out of the test site, which includes writing notes or recording anything electronically.
• Having any written material other than the test materials CSLB provides.
• Talking with other test takers during the exam.
• Copying someone's answers or letting yours be copied.
• Sharing details of test questions with a school, a person or a business, as opposed to CSLB exam staff.

The penalties are serious: automatic failure, loss of fees already paid, possible misdemeanor prosecution, and a one-year bar on applying for any CSLB license from the exam date. (CSLB Get Licensed to Build, p. 26) State law separately makes it a misdemeanor for anyone other than the named examinee to take the qualifying exam for an applicant. (License Law Book 2026, B&P §7068.5)

That fifth bullet applies after you leave, too. Describing questions to a study group, a school or an online forum is on the list, which is a good reason to study from the guide's topic outline rather than from other people's memories of the test.

Arrange help before the day, not at check-in

Two requests have to be made ahead of time. If you have difficulty understanding or reading English, CSLB may allow a translator to read the exam, and CSLB must approve the translator you choose in advance. (CSLB Get Licensed to Build, p. 21) You ask by checking the box for it on the application, and CSLB then sends further information. (CSLB Get Licensed to Build, p. 21)

For a disability accommodation, you must tell CSLB about the need, because CSLB is not required to provide an accommodation it does not know about. (CSLB Get Licensed to Build, p. 21) The request goes on an accommodation request form, which you can include with the application. (CSLB Get Licensed to Build, p. 15)

After the exam: what you will see and what you will not

You get your result before leaving the test center. Passing candidates are told they passed without a detailed score, while others see on screen how they did on each section. (CSLB Get Licensed to Build, p. 25) You cannot review the questions afterward, although you can type a comment on a question before it is scored. (CSLB Get Licensed to Build, p. 26)

If you pass, the qualifier receives a letter at the test site that outlines what CSLB still requires before it can issue the license. (CSLB Get Licensed to Build, p. 27)

One-page checklist

1. Confirm your appointment from the exam notice and read the Candidate Information Bulletin.
2. Request a translator or accommodation before you test, not on the day.
3. Put one accepted photo ID in your pocket and check that it has not expired.
4. Plan to arrive 30 minutes early.
5. Leave notes and reference books behind, and expect a calculator to be provided.
6. Afterward, keep the exam questions to yourself.
