At ADIT Instructor Training we are happy to to offer ADI Part 1 training at our office. The good news is that trainees are able to study for Part 1 around their other commitments.

At the ADIT office, trainees can learn how to approach and go through the theory test questions and hazard perception video clips as part of our instructor training course.

About the ADI Part 1 Test

ADI Part 1 Theory Test

There are no limits to how many times a candidate can take the ADI part 1 test in order to pass. However, in order to retake the test, a new test appointment date has to be booked.

The Part 1 Test is done on a computer in two sections and takes approximately 1 hour 45 minutes to complete. The two sections are:

  • multiple-choice questions
  • hazard perception video clips

Both sections of the test must be passed at the same sitting for the trainee instructor to receive an ADI Part 1 pass.

For those not confident at using computers, staff at the test centres are able to help with questions before the test begins - although the onscreen help is very clear and comprehensive. As part of the onscreen help, it's also possible to try a short practice session on the computer before staring the actual test.

ADI Part 1 Theory Test

The first section of the ADI Part 1 is a test of knowledge, where candidates have 90 minutes to answer 100 multiple choice questions.

It's easy to navigate through the questions on the computer screen, and possible to skip to the next question and return later on if you wish. It's also possible to return to questions in order to change answers.

Part 1 is designed to test a potential driving instructor (PDI) on their knowledge of:

  • the Highway Code
  • rules of the road
  • instructional techniques

The knowledge required for ADI Part 1has been split into 4 groups to ensure candidates are tested on all areas necessary for teaching pupils. The 4 groups are:

  • road procedure
  • traffic signs and signals, car control, pedestrians, mechanical knowledge
  • driving test, disabilities, law
  • publications, instructional techniques

ADI Part 1 Hazard Perception Test

After a short break, the second part of the test begins. The hazard perception section consists of 14 video clips which are each around 1 minute long.

Before the real test starts, there is a tutorial on the compouter screen which explains what to do.

ADI Part 1 videos contain footage of different scenarios filmed from the driver's point of view. The candidate taking the test is basically playing the role of the driver, deciding when a hazard situation is developing, and whether it's important enough to take action such as changing direction or speed.

Candidates score marks for recognising a developing hazard and pressing the mouse button as it is happening. Higher marks are scored if the mouse is clicked earlier on during the developing hazard, and less as the hazard develops. The maximum score for each hazard is 5 points.

The Marking System

The total score required to pass Part 1 is 85%. The minimum pass marks for each section are as follows:

  • multiple-choice - 80% (20 correct questions from each of the 4 groups)
  • hazard perception - 57 out of a possible 75

Candidates will receive their results before leaving the test centre, and be notified of the scores they received for each section.
