Missouri Permit Test Passing Score: 20 of 25 Questions (80%) (2026)

You must answer 20 out of 25 questions correctly on each section of the Missouri permit test, a passing score of 80%. This allows a margin of error of 5 incorrect answers per section. A 6th incorrect answer causes an immediate fail.

What Is Missouri's Permit Test Passing Score and Structure?

The Missouri Class F written knowledge test has 25 questions, and you need 20 correct answers (80%) to pass.

Road-sign recognition is a separate required test. This page owns the passing-score question; detailed road-sign content belongs in the dedicated road-sign guide.

Review the Missouri Driver Guide sample questions before testing so you are familiar with the state's question style.

How many questions can you miss on the Missouri permit test and still pass?

You can miss up to 5. The Class F written test has 25 questions and requires 20 correct answers, or 80%, to pass.

Does Missouri round a permit-test score of 19 out of 25 up to 80%?

No. Nineteen correct answers is 76%, so it does not meet Missouri's published requirement of 20 correct answers out of 25.

Do road-sign test results use the same 80% passing score?

The published 20-out-of-25 / 80% rule applies to the Class F written test. Missouri treats road-sign recognition as a separate examination component and its public guidance does not state that the same 20-of-25 formula applies to that portion. Do not use the written-test score formula for the sign test unless MSHP specifically tells you to.

What Does a Score Below 20 of 25 Mean?

A score of 19 or lower does not meet Missouri's 80% written-test passing requirement. This page stays focused on how the passing score works; retake timing, attempt limits, and what to do after a failure are covered in the dedicated failed-test guide.

Build a Buffer Above the 80% Passing Mark

Before the real exam, aim to score comfortably above 80% on several different practice sets so one weak topic does not push you below the passing mark.

Review sign recognition separately and use the current Driver Guide for Missouri-specific rules. For office documents, fees, station hours, and retake procedures, use the dedicated pages for those topics.
