What's the Passing Score on the Idaho Permit Test?
34 out of 40 questions correct — 85% — passes Idaho's instruction permit knowledge test, delivered through a computer-adaptive format.
A demanding threshold, delivered adaptively
85% sits above what most states require, and Idaho's test doesn't wait around to confirm it: the exam ends the instant you reach 34 correct answers, whether that happens on question 34 or question 40.
That adaptive format means a string of early misses can't be quietly offset later — every answer counts from the very first question.
What the adaptive format means for your strategy
Since the test can end right at your 34th correct answer, there's no benefit to rushing through early questions — a careless miss near the start costs exactly as much as one near the end.
Treat every question with the same care you'd give a make-or-break question late in the exam, because functionally, it is one.
Restrictions worth getting exactly right
Idaho's underage-license passenger restriction — one passenger under 17, non-family, for the first six months — is easy to blur with the different age cutoffs other states use.
Read the explanation on every practice question, correct or not — it's what actually closes these gaps, not just re-answering until you get lucky.
