You'll take the state-approved DPS written test at the end of Level 1 (the first six hours of the course). This means that you won’t need to take the Written Knowledge Test at the DPS. The test consists of 30 multiple-choice questions. You’ll have one hour to complete the test and you must score at least 70% or better (at least 21 out of 30 questions correct) in order to pass. If you fail, you can take the test again 24 hours later. There is no limit on how many times you can take the written test and you don’t have to pay again to take it more than once.
