CNA Written Exam Format: 70 Questions, Two Hours, and the Oral Option

How many questions are on the NNAAP written exam, how long you get, how the oral version works, and how Tennessee's, Florida's and Texas's formats differ, with a pacing plan for each.

Short answer

In Pennsylvania's NNAAP written exam, you get 70 multiple-choice questions in two hours; other states may use different formats. Ten are unscored pretest items mixed in with the 60 scored ones, and you cannot tell which they are. The oral version has 60 multiple-choice questions plus 10 word-recognition items in the same two hours, and you must pass both sections. Other states differ: Florida's Prometric written test has 60 questions in 90 minutes, and Credentia's Tennessee pages give its knowledge exam 75 questions on one page but a conflicting count on another.

The NNAAP written exam: 70 questions, 60 scored, two hours

As checked on October 18, 2026, Credentia's Pennsylvania handbook describes the NNAAP written exam this way:

  • 70 multiple-choice questions. The 2024 outline says 10 of them are pretest items that are not scored, so 60 count toward your result. The outline's item counts add up to 60.
  • Two hours. You are told when 15 minutes are left.
  • One answer per question. You fill in one oval on the answer sheet or on screen. At a test center, marks in the test booklet are not accepted; only the separate answer sheet counts.
  • Online or at a test center, in English or Spanish (Pennsylvania's options).

Credentia's California, Virginia, Colorado, Alabama, Rhode Island and South Carolina pages give the same 70 questions. Some of them say the written exam is in English and point candidates who have trouble reading English to the oral exam. What's on the CNA written exam covers how the 60 scored items divide among the nine content areas.

The ten pretest questions you cannot spot

The pretest items are mixed in with the scored ones and look the same. Credentia collects statistics on them for future exams, and they do not count. Since you cannot tell which ten they are, treat every question as scored. Skipping a hard item because it "might be pretest" only costs you if it was a real one.

Pacing the CNA written exam, state by state

Divide the time by the number of questions and you get your average budget per question. Each figure below is labeled with its source, because states differ.

Exam and source (as checked on October 18, 2026)QuestionsTimeAverage per question

Tennessee Knowledge exam, overview page count75120 minutesAbout 1 minute 36 seconds

For the standard NNAAP exam, an even pace finishes with no time to spare. A steadier plan is to aim for about a minute and a half per question, which leaves you a reserve for flagged items. This checkpoint plan is a Passy suggestion, not a Credentia rule:

Minutes into the examEven pace reaches aboutPassy checkpoint (1.5 minutes a question)
30Question 17Question 20
60Question 35Question 40
90Question 52Question 60
105Question 61Question 70, then review
120Question 70Time is up

On this plan, the 15-minute warning arrives about when you finish your first pass, so you spend those minutes on the questions you marked. At a test center, bring the watch with a second hand that Pennsylvania's handbook asks for, so you can check your pace yourself.

To test the plan before exam day, pace yourself on CNA written-exam practice questions with a watch beside you and check whether you reach about ten answers every 15 minutes.

Test center or online: what changes on the written exam

Pennsylvania offers the written exam both ways. As checked on October 18, 2026, its handbook describes them like this:

Test centerOnline, with a live proctor
Where your answers goA separate paper answer sheet. Booklet marks do not countOn screen
What to bringTwo forms of current, signature-bearing ID, one with a photo, three sharpened No. 2 pencils, an eraser, and a watch with a second handThe same two forms of ID
EquipmentProvidedA desktop, laptop or Chromebook with one monitor (no phones or tablets as the test device), plus a phone or tablet for a 360-degree room scan in the ExamRoom AI app
Arrival or check-inArrive 30 minutes early. Late candidates may not test, and fees are not refundedCheck in up to 30 minutes before your appointment, after running the required system test
RoomThe test center'sA private room with no one else in it

In Pennsylvania, missing ID means you cannot test, the fee is not refunded, and the absence counts as one of your three opportunities. CNA exam day has the full checklist.

The CNA oral exam in brief

Federal rules let every candidate choose between a written and an oral exam, and an oral exam must be read from a prepared text in a neutral manner (42 CFR 483.154(b)(1)). On the NNAAP, as Credentia's Pennsylvania handbook describes it:

  • 60 multiple-choice questions, each read twice, and 10 reading-comprehension (word recognition) questions on common job-related words, each read three times.
  • Two hours for the whole exam.
  • Both sections must be passed to pass the oral exam.
  • Delivery: an MP3 player at Pennsylvania test centers, and a recorded voice online.

Tennessee's oral exam works differently: 75 multiple-choice questions given on a computer, which can be repeated as many times as needed. Credentia's Virginia, Colorado, Alabama, Rhode Island and California pages say you must request the oral exam when you apply, and Florida's Board of Nursing says the same for its oral or Spanish test. The CNA oral exam guide covers who should choose it.

Two CNA question-count conflicts to know about

Tennessee. As checked on October 18, 2026, three Credentia Tennessee pages describe the Knowledge exam differently:

  • The overview page says "seventy-five (75) multiple-choice questions," with "ten (10) experimental questions intermingled" that do not count.
  • The outline page says "seventy-five (75) multiple choice items with an added ten (10) items that are pretest."
  • The Knowledge Exam page says "seventy-five (85) multiple-choice questions."

The overview and Knowledge Exam pages both give two hours and a 75% passing score. Passy does not pick a count. Plan your pacing for the higher number, and ask Credentia or the Tennessee Health Facilities Commission which is right for your test date. The CNA passing score guide explains Tennessee's 75%.

U.S. Virgin Islands. The outline page says the written exam "is comprised of sixty (70) multiple-choice items," while the same page elsewhere says seventy (70). The Pennsylvania handbook and the other Credentia pages checked give 70, which matches the written-exam description on the Virgin Islands page itself.
