The passing score is usually 80 percent, which means you need to answer about 24 out of 30 questions correctly
Most states require you to score 80 percent on the written permit test to pass. Since most permit tests have 30 questions, that means you need to get 24 questions right. Some states use 35 or 40 questions instead, which changes the exact number you need but keeps the 80 percent threshold. A few states — including South Carolina and Tennessee — set the passing score at 70 percent, so you would need 21 out of 30 questions correct in those states.
The passing score does not change based on how many times you have taken the test or whether you are retesting. You need the same score on your first attempt as you would on your fifth. Some states let you retake the test the same day if you fail; others require you to wait 24 hours or longer before trying again.
Key Takeaways
- The passing score is 80 percent in most states, which equals 24 correct answers out of 30 questions on a standard permit test.
- A few states set the passing score at 70 percent instead, so you need to know your state's specific requirement before test day.
- The number of questions on the test varies by state — some use 30, others use 35 or 40 — but the percentage threshold stays the same.
- You must reach the passing score on every attempt; there is no curve, no partial credit, and no rounding up from 79 percent.
How the passing score breaks down by state
The 80 percent rule applies in the majority of states, including California, Florida, New York, Texas, Ohio, and Pennsylvania. In those states, a 30-question test requires 24 correct answers. If your state uses a 35-question test at 80 percent, you need 28 correct. At 40 questions and 80 percent, you need 32 correct.
South Carolina, Tennessee, and a small number of other states use 70 percent as the passing score. In South Carolina, the permit test has 30 questions, so you need 21 correct to pass. Tennessee also uses 30 questions with a 70 percent threshold. Check your state's DMV website or your permit test study guide to confirm the exact passing score and number of questions before you sit for the test.
Some states also have separate passing scores for different sections of the test. For example, a few states require you to pass the general knowledge section and the road signs section separately, each with its own 80 percent threshold. If you fail one section but pass the other, you may have to retake only the failed section on your next attempt, depending on state rules.
What happens if you score just below the passing line
If you get 23 out of 30 questions correct on an 80 percent test, you have scored 76.7 percent — below the passing threshold. There is no rounding, no partial credit for nearly correct answers, and no second chance within the same test session. You fail and must retake the entire test.
Most states allow you to retake the permit test within a short window. Some let you test again the same day at no extra cost; others charge a retest fee (usually $5 to $15) and require you to wait 24 hours or a few days. A few states impose a longer waiting period, such as one week, before you can attempt the test again. Check your state's DMV rules on retesting before your first attempt so you know what to expect if you do not pass.
How many questions you can miss and still pass
| Passing Score | Test Length | Questions You Need Correct | Questions You Can Miss |
|---|---|---|---|
| 80% | 30 questions | 24 | 6 |
| 80% | 35 questions | 28 | 7 |
| 80% | 40 questions | 32 | 8 |
| 70% | 30 questions | 21 | 9 |
On a standard 30-question test with an 80 percent passing score, you can miss 6 questions and still pass. That means you have a small margin for error, but not much. If you miss 7 questions, you score 76.7 percent and fail. On a 35-question test at 80 percent, you can miss 7 questions. On a 40-question test at 80 percent, you can miss 8 questions.
In states with a 70 percent passing score, the margin is wider. On a 30-question test, you can miss 9 questions and still pass with exactly 70 percent. This does not mean the test is easier — the questions themselves are often harder — but it does give you more room for mistakes.
Common mistakes that cost you points on test day
Many people fail the permit test not because they do not know the material, but because they misread questions or rush through them. The most common mistake is not reading the entire question before choosing an answer. Some questions ask "which of the following is NOT true" or "which is the safest action" — if you skim and miss the negative or the specific instruction, you will pick the wrong answer even if you know the rule.
Another frequent error is guessing on questions you are unsure about without using the process of elimination. On a multiple-choice test, eliminating obviously wrong answers first increases your odds of guessing correctly. If you are stuck between two answers, read both again carefully — often one will contradict something you learned in your study materials.
Time pressure also causes mistakes. Some people rush through the first 15 questions to "get ahead" and then make careless errors. Others spend too long on one difficult question and run out of time at the end. Pace yourself: if the test has 30 questions and you have 30 minutes, spend about one minute per question on average, leaving a few minutes to review flagged questions at the end.
How to prepare so you score well above the passing line
Studying only until you think you can barely pass is risky. If you aim for exactly 24 out of 30 correct, one bad day or one misread question puts you below the line. Instead, study until you can consistently score 28 or 29 out of 30 on practice tests. That gives you a safety margin and builds confidence.
Use your state's official DMV study guide and practice tests. Many states publish the exact questions that appear on the real test, or questions very similar to them. Take the practice test multiple times, not just once. On your first attempt, you are learning which topics you need to review. By your third or fourth practice test, you should be scoring at or above the passing threshold consistently.
Focus your study time on the topics that trip you up most. If you keep missing questions about right-of-way rules, spend extra time on that section. If you struggle with road signs, drill those until you can identify them when ready. Spending two hours reviewing material you already know is less useful than spending 30 minutes on the topics where you are weakest.
What your score means after you pass
Once you pass the permit test, your score does not appear on your permit or affect your driving record. The DMV records only that you passed, not whether you scored 24 out of 30 or 30 out of 30. Your score also does not carry forward to the road test — passing the written test and passing the driving test are separate milestones.
Some states do use your permit test score to determine how long you must hold your permit before taking the road test. For example, a few states require a longer waiting period if you scored just barely above the passing line, on the theory that you need more practice time. Check your state's rules on permit holding periods to see if your score affects when you can schedule your driving test.
Frequently Asked Questions
Can I pass the permit test with a score of 79 percent?
No. Most states require exactly 80 percent, and 79 percent is a failing score. There is no rounding up, no partial credit, and no exceptions. You must retake the test and score 80 percent or higher to pass.
Do I get to see which questions I missed after I fail?
This varies by state. Some DMV offices print out your test results and show you which questions you answered incorrectly. Others do not provide this feedback. Ask the test administrator before you leave whether you will receive a score report. If you do, use it to study the topics you missed before your next attempt.
Is the permit test harder in some states than others?
The passing score threshold is the same in most states (80 percent), but the difficulty of the questions themselves can vary. States write their own test questions based on their own traffic laws. A question about a rule that is unique to your state may be harder because you have not seen it in other states' materials. Stick to your state's official study guide rather than generic permit test prep.
What if I pass the permit test but fail the road test?
Passing the written test and passing the driving test are completely separate. You can pass the permit test on your first try and fail the road test multiple times, or vice versa. Each test measures different skills. You will need to retake whichever test you failed.
Does my permit test score affect my insurance rates later?
No. Insurance companies do not see your permit test score. They see only your driving record once you have a license. How well you did on the written test has no impact on your insurance rates or your driving record.
