JASPA's 2025 first-session results give the Class 3 written pass criterion (chassis, gasoline, diesel) as "1問1点、30点満点に対し21点以上": one point per item, 21 or more out of 30. Only the total counts.

How to read these figures
About seven in ten pass, but many candidates are Japanese vocational students who have completed a full course. For foreign candidates the biggest barrier is usually reading speed in Japanese. So practise until you are steadily above the mark, not just touching 21.
Your practice target
Aim for 24/30 or more on three or four papers in a row before the test. A three-item margin protects you against unfamiliar or slow-to-read items. The app scores against 21/30 and shows the score of every paper so you can track your progress.
