ADI Part 1 Theory Test: A Tough Nut to Crack

Why the current pass rate means revision isn’t optional—it’s essential

Becoming an Approved Driving Instructor in the UK starts with the ADI Part 1 theory test—a formidable first hurdle. This isn’t your average learner driver theory test. You’ll be assessed across 100 multiple-choice questions and hazard perception, with a high bar to clear. According to the DVSA, you must score at least 85 out of 100 overall, and hit a minimum of 20 out of 25 in each of the four question categories. The hazard perception section demands a minimum of 57 out of 75

Yet despite rigorous standards, the pass rate remains surprisingly low. As of early 2025, only around 37 percent of candidates pass ADI Part 1—meaning six in ten fail

What that failure rate means

• High cost, high stakes: Each attempt costs about £81, and with a fail rate of 63%, costs—and frustration—stack up fast
• Exam belt tightening: This pass rate is significantly lower than the ~80% recorded in earlier years, and much lower than the average across other ADI parts
• Professional expectations: As a future instructor, you're expected to display knowledge and teaching insight far beyond that of learner drivers—making Part 1 a true test of vocational readiness

Why not skimp on revision—use the best resources

With numbers like these, under-preparation is a luxury few can afford:

• adionline.co.uk
  Designed specifically for ADI candidates, this site delivers complete coverage of all four theory bands, breaking down complex content into digestible sections. ORDIT-registered trainers walk you through every specialist question and teach hazard perception tactics tailored for instructors
• drivertrainingtheory.co.uk
  This is the revision hub you don’t want to overlook. Packed with mock tests, question banks, and topic-by-topic drills, it's ideal for those aiming to understand—not just memorise—the material

These platforms strike the perfect balance between teaching depth (so you grasp legal/regulatory nuance) and practice volume (so you refine speed and accuracy). That’s exactly the kind of strategic revision needed to lift your preparation from “adequate” to “instructor‑grade”.

Strategies to raise your odds

1. Hit the weak spots
   The ADI Part 1 categories are specialist: Road Procedure; Signs & Signals; Testing Law; and Instructional Techniques. Use targeted quizzes on adionline to shore up any weak bands
2. Mock under pressure
   Time yourself. Review each question, especially hazard perception clips. Learn not just to spot hazards—but to spot them early.
3. Consistent, smart practice
   Build a steady revision routine. Short daily sessions often outmatch marathon cramming.
4. Walk before you run
   Start with drivertrainingtheory to reinforce fundamentals. Then use adionline to layer in the ADI‑specific depth.
