CBP Officer Entrance Exam Practice Test 2026: 30 Free Questions

Correct answer: B. Every interpreter at the terminal has passed the test, so some people who passed the test are interpreters there; an "all" group is treated as having members. The claim that everyone who passed is assigned to the terminal reverses the "all" statement. The claim that some interpreters have not passed contradicts the first sentence. Some interpreters teach evening classes, but that does not make every evening teacher a terminal interpreter, and the paragraph says nothing about interpreters at other terminals.

Correct answer: D. A "none" statement works both ways: if no boat docked there on Tuesday was a fishing boat, then no fishing boat was docked there that day. The paragraph says that several docked boats were inspected, not every one, and it does not say whether staff inspected boats anywhere else, so neither claim with "every" follows. Nothing says any fishing boat was inspected, and a fact about one day is not a rule that bans fishing boats.

Correct answer: A. The valid conclusion is the contrapositive: if the result (being held overnight) did not happen, the condition (fresh fruit arriving after 4:00 PM) did not happen either. Saying that every shipment held overnight is late fresh fruit is the converse, and saying that early fruit is not held is the inverse; neither follows, because other shipments may be held for other reasons. The paragraph does not say when the pears arrived, and it never says the cold room holds only fruit.

Correct answer: E. "Some" means at least some and says nothing about the rest, so the paragraph does not show that any issued radio went unrepaired; that is the conclusion that cannot be drawn. The other four follow. The issued radios that were repaired came back with new batteries, and a "some" statement can be turned around. The second sentence says every repaired radio came back with new batteries, and "no radio ... without new batteries" is a double negative that says the same thing.

Correct answer: C. The "unless" rule means that a visitor without a staff badge signs the logbook. Theo Dorsainvil did not sign, and therefore he must hold a staff badge; the claim that he does not hold one contradicts the paragraph. A staff badge does not show where he works, and one visitor's facts say nothing about every visitor that day.

Correct answer: A. "Only with an officer who has completed the course" makes the course a requirement for every inspection with a dog, so Officer Ruvalcaba, who took a dog out, has completed it. A requirement is not a promise: it does not say that everyone who completed the course takes a dog out. Some course graduates work nights, but that tells us nothing about Officer Ruvalcaba's shift or about night-shift officers without the course. The rule limits inspections with a dog, not all inspections, so officers without the course may still go out on other inspections.

Correct answer: E. The mechanics who inspect the forklifts are all county employees, and no county employee works on weekends, so none of these licensed mechanics works on weekends. The claim that every county employee is a licensed mechanic reverses the "all" statement. Weekend inspections would need a mechanic working on a weekend, which the paragraph rules out. The paragraph says nothing about county mechanics who do not inspect the forklifts or about the warehouse's hours.

Correct answer: B. The paragraph says that selling hot meals requires a permit, not that every permit holder sells hot meals; that is the converse, and it cannot be concluded. The other four follow. Hot meals lead to a permit and a permit leads to a passed inspection, which gives both the chain and its contrapositive (no passed inspection, no hot meals). The contrapositive of the first sentence (no permit, no hot meals) and the double negative "no truck ... has an operator without a permit" also restate the rule.

Correct answer: D. "Most" gives at least "some": at least some spring trainees passed on the first try, and they received a certificate within a week. The claim that every certificate holder passed on the first try reverses the "all" statement in the second sentence. "Most" is not "all", so the paragraph does not show that every spring trainee got a certificate, and it says nothing about what happened later to trainees who failed.

Correct answer: C. The rule covers every employee outside the exception, and Grant Ottersen is an employee who is not on the night shift, so he attends the meeting. Not working nights does not mean he works days, since the department also has an evening shift. The paragraph does not say who leads the meeting or that only department employees attend. The claim that some employees off the night shift miss the meeting contradicts the rule.

Correct answer: A. Only some of Monday's air packages hold medical samples, and the paragraph says nothing about the others, so it cannot be concluded that none of them is marked nonperishable; that claim turns "some" into "all". The other four follow. Medical-sample packages go in the refrigerated room and nonperishable packages never do, which means no medical-sample package is marked nonperishable, and a "none" statement works both ways. Monday's packages with medical samples are in the refrigerated room, and therefore they are not marked nonperishable.

Correct answer: E. Team 4 did not file with the night supervisor, so by the contrapositive of the if-then statement it did not check the west tracks; since every team checks one side or the other each day, Team 4 checked the east tracks. Checking both sides is ruled out by the first sentence. The claim that every team filing with the night supervisor checked the west tracks is the converse, and the claim that east-track teams never file with that supervisor is the inverse. One team's facts say nothing about every other team on Tuesday.

Correct answer: C. The paragraph shows that Iris Pazmino passed the quiz before her renewal in May and that the quiz is given only on first Tuesdays, but it does not say in which month she took it; she may have passed in April or earlier, so the claim about the first Tuesday of May cannot be concluded. The other four follow. A renewal requires a pass, and the quiz is given only on Tuesdays. The two statements about operators who have not passed restate the "only after" rule, one of them as a double negative.

Correct answer: B. A statement that many bridges were not repainted does not tell you whether any bridge was repainted; it implies nothing about the rest, so that conclusion cannot be drawn. The other four follow. The many bridges that were not repainted got unfavorable ratings, and therefore they were not opened to heavy trucks. A "none" statement works both ways, and a bridge opened to heavy trucks cannot have an unfavorable rating, which means it must have been repainted.

Correct answer: D. Recording a seal number requires the seal training course, and no September hire has finished it, so no September hire has recorded a seal number. Other inspectors can still record numbers, and containers can therefore be released while September hires are on duty. The "only" statements set requirements, not promises: they do not say that every trained inspector records numbers or that every recorded container is released. The paragraph says nothing about when the September hires will finish the course.

Correct answer: B. The subject is "list," which is singular, so the verb must be "is"; the words "of approved vendors" between them do not change the subject. "Vendors" is a plain plural here, not a possessive, and a comma after "cafeteria" would split the subject from its verb. Because the verb does not agree with its subject, a correction is necessary.

Correct answer: C. "Effect" is the noun that means a result; "affect" is usually a verb that means to influence. After "a positive," the sentence needs the noun, so "affect" must change to "effect." The subject "plan" is singular, so "is expected" is right, and "positive" is an adjective that correctly describes the noun.

Correct answer: A. A title that comes right before a person's name is capitalized, as in "Lieutenant Genevieve Kovacevic"; the same word after a name, as in "Genevieve Kovacevic, the lieutenant," stays lowercase. A comma sets off an introductory phrase such as "On Tuesday," so that comma stays. Nothing in the sentence calls for the past perfect "had reviewed," because no other past event comes after the review.

Correct answer: D. The sentence is correct as written. Two inspectors wrote reports, so the plural possessive "inspectors'" (apostrophe after the s) is right; "inspector's" would mean one inspector. The subject "reports" is plural and takes "were filed," and the comma before "and" is needed because "and" joins two independent clauses.

Correct answer: B. The writing rules in the official guide call for a comma after every item in a series, including the item before "and." A comma therefore belongs after "notebook." "Officers" is a plain plural subject, not a possessive, and "at the start of" is the standard phrase. The sentence is missing the series comma, so a correction is necessary.

Correct answer: A. Use "who" for people and "which" for things, so "inspectors which" should read "inspectors who." The clause "who completed the new radio course last month" tells which inspectors are meant, so it is restrictive and takes no comma. The move to the gate happens next June, so the future "will begin" is correct and "began" would not fit.

Correct answer: D. The sentence is correct as written. "Committee" is a collective noun that acts as one group here, so it takes the singular "is," and the possessive pronoun "its" has no apostrophe ("it's" means "it is"). A title is capitalized only when it comes right before a name, so "the port director" stays lowercase.

Correct answer: C. The sentence uses "and" to join two independent clauses, each with its own subject and verb ("the cargo scanner ... stopped" and "the repair crew did not arrive"), so a comma goes before "and," right after "noon." A comma after "scanner" would separate the subject from its verb. Changing "stopped" to "stops" would shift the first clause into the present while the second stays in the past.

Correct answer: A. An opening phrase such as "While checking the cargo list" must be followed by the person doing the checking. The sentence that puts "one crate" right after the phrase has a dangling participle and also shifts into the passive voice. The sentence with "notices" mixes the present tense with the past perfect "had been," and the sentence with the comma after "inspector" puts a comma between the subject and its verb and drops the comma after the opening phrase. Only the sentence in which "the inspector noticed" is correct.

Correct answer: C. The port has only one new scanner, so the clause "which arrived on Monday" adds extra information and does not identify which scanner is meant. It is nonrestrictive and must be set off by a pair of commas, one before it and one after it. The sentences with only one of those commas are wrong, because the single comma splits the subject from its verb. The sentence with "are" breaks subject-verb agreement: the subject is the singular "scanner," and the clause between them does not change that.

Correct answer: D. Only one sentence spells both words correctly: "separated" (with "par" in the middle) and "necessary" (one c and two s's). The other sentences misspell one or both words as "seperated," "neccessary," or "neccesary." Everything else in the four sentences is the same.

Correct answer: B. Items joined in a series should have parallel form. The correct sentence uses the same pattern for all three items ("how to inspect," "how to read," and "how to write"), and its verb "covers" agrees with the singular subject "course." One sentence breaks the pattern with "reading," another shifts to the passive "how a report should be written," and the last uses the plural verb "cover" with a singular subject.

Correct answer: A. Paragraph 2 introduces the new parking plan, so it comes first. Paragraph 4 begins with the words "Under the plan" and must therefore follow the paragraph that introduces the plan, and paragraph 1, about the shuttle to Lot C, depends on paragraph 4, which first names Lot C. Paragraph 3, which tells readers where to send questions, closes the memo. The order as given and the order that starts with paragraph 1 open with a detail before the plan is introduced, and the order that starts with paragraph 4 opens with "Under the plan" before any plan has been named.

Correct answer: B. A report of events should follow the order in which they happened. Paragraph 3, the first word of the leak at 6:40 AM, comes first; paragraph 1 tells how the writer went to the truck and called the fire unit; paragraph 4 tells what the fire unit did when it arrived at 6:55 AM; and paragraph 2, with the driver's return at 7:20 AM and the reopening, comes last. The other orders either open with the writer going to the truck "at once" before anyone has reported the leak or have the fire unit arrive before anyone called it.

Correct answer: C. This passage moves from the particular to the general: it reports what happened and ends with the lesson drawn from it. Paragraph 2 sets the scene with the rise in requests, paragraph 4 explains the result ("Because each request was handled by hand"), paragraph 3 describes the fix ("To shorten the wait"), and paragraph 1 gives the outcome and the general statement that closes the passage. The order as given and the order that opens with paragraph 1 put the June outcome before the problem is described, and the order that puts paragraph 3 second describes a fix for a wait the reader has not yet heard about.
