The Guam Written Knowledge Test: Format, Fees, and Test Day

Quick Answer: Guam's written knowledge test is widely reported as 40 multiple-choice questions with a 32-correct (80%) passing standard — only eight wrong answers. Treat that as the working figure, but note that neither the Driver's Handbook nor 16 GCA § 3113.1 publishes a question count or pass mark, so confirm it with Rev & Tax when you schedule. You pay $15 cash for the English test ($35 for a test in another language), and the exam is proctored by the University of Guam Global Learning and Engagement (GLE) office rather than at the Department of Revenue and Taxation counter.

The number that should shape your studying

Most driver-license knowledge tests in the United States allow you to miss around a quarter of the questions. Guam is reported to be stricter: 40 questions with 32 correct required, an 80% standard whose entire margin for error is eight questions.

A sourcing note, because it matters. Every other number in this guide comes from an official source — the Guam Driver's Handbook, 16 GCA, or guamtax.com. This one does not. 16 GCA § 3113.1 governs the written test and learner's permit but prescribes neither a question count nor a pass mark, and the figure appears nowhere in the handbook or on guamtax.com. It is consistently reported by test-takers and prep sites and is very likely correct, but you should verify it at the counter rather than treat it as statute.

That single fact should change how you prepare. On a 75%-pass test you can afford to skip a low-frequency topic and absorb the damage. On Guam's test, one neglected topic — parking distances, say, or the graduated-licensing curfews — can easily account for three or four questions and put you within one careless error of failing. The practical consequence is that breadth beats depth here: it is far better to know every chapter of this guide reasonably well than to know three chapters perfectly and one not at all.

What the test covers

The questions are drawn from the material the Government of Guam publishes for drivers: traffic signals and signs, right-of-way, turning and passing, speed and stopping, parking, sharing the road with pedestrians and other vehicles, safe-driving practice, impairment and distraction law, and the licensing rules themselves. Every one of those areas has a chapter in this guide.

A meaningful share of questions are Guam-specific, and this is where mainland study material actively hurts candidates. Guam is a U.S. territory with its own traffic code — Title 16 of the Guam Code Annotated — and its own licensing agency. Fees, minimum ages, graduated-licensing rules, curfews, and penalties are set by Guam law, not by any state. If you study a mainland practice test, you will confidently learn wrong answers.

Fees and payment

The written examination fee is $15 for the English-language examination. If you need the examination administered in a language other than English (LOTE), the fee is $35, reflecting the additional cost of providing that version.

Payment is cash only. Checks and cards are not accepted for the examination fee, and candidates are routinely turned away for arriving with only a card. Bring exact cash if you can.

Separately, when you pass and go to collect your learner's permit at Revenue and Taxation, there is a $10 permit fee. Budget for both.

Where the test is actually given

This surprises many first-time applicants: you schedule through the Department of Revenue and Taxation (Rev & Tax), but the examination itself is proctored by the University of Guam's Global Learning and Engagement (GLE) office — the unit formerly known as PIP — in the MARC Building, second floor, with testing conducted in Annex A.

So the process has two physical stops:

1. Rev & Tax — apply, get scheduled, receive your scheduling slip.
2. UOG GLE — sit the examination on the scheduled date.
3. Rev & Tax — return after passing to pay the permit fee and collect the permit.

Test-day logistics

Seats in a session are finite, so late arrivals may simply not be admitted. The one-hour buffer is not a courtesy suggestion; it is the check-in window. Turning up at the scheduled time is turning up late.

Results are posted online rather than handed to you at the door, so you should know where to look before you leave the building.

Retakes, and the stricter rule for foreign-license conversions

If you fail, you may retest, subject to rescheduling and paying the fee again.

Applicants converting a foreign driver's license face a tighter regime under Guam law and Rev & Tax practice: after two failures a mandatory seminar is imposed before further attempts, and there is a three-attempt cap. If you hold a foreign license, treat your first sitting as if it were your only one — the cost of casual preparation is much higher for you than for a first-time local applicant.

What to do with this section

Write down three numbers and check them the night before: 40 questions, 32 to pass, one hour early. Then confirm you have cash, photo ID, and your scheduling slip in one place. A surprising proportion of failed test days are administrative, not academic.
