The Iowa DOT does not publish the exact number of questions or the passing score. These are the best figures available, and they are the ones DMV Champ’s exam simulator uses. Check the current Iowa handbook before your exam.
Iowa’s exam is a middle-length one: 31 jurisdictions ask fewer questions and 17 ask more. You need 80% to pass, which means you can miss 7 questions and still get your permit. There is no time limit, so read every question twice.
The exam is given by the Iowa DOT (Iowa Department of Transportation). Its questions come from the official Iowa driver’s handbook, which is also where every DMV Champ question is checked.
The Iowa Driver’s License Manual calls it the knowledge test. Passing it is how you get an instruction permit.
36 topics in Iowa: the 34 every state tests, plus winter driving and flooding, because the Iowa handbook teaches them.
Exam simulator
Pick Iowa once in the app and every simulated exam uses these figures. Nothing is revealed mid-exam, and each attempt is graded against the 28-correct passing score at the end. Retake an exam as often as you like, reordered each time.
What you study
Signs and signals, road rules, safe driving and driving laws. The topics come from the AAMVA guidelines every state builds its exam on, checked against the Iowa handbook. Each is a short group of questions you can get through in a few minutes, and every answer is explained the moment you check it.
No chapters to read first. Every practice question carries its answer and the reasoning, so a wrong answer is how the next thing is taught.
A question you get wrong returns until you get it right. Once you’ve answered every new question and corrected every mistake, you’ve finished the learning phase.
The score you’d likely get on the Iowa exam today, with the 28-correct passing score marked on it and a 14-day trend.
