ADI Part 3 is test of your instructional ability. The test lasts for approximately one hour, and is the final part of the qualifying process. When you pass ADI part 3 you become a fully qualified driving instructor.
The following DVSA video gives an overview of what is involved in ADI part 3.
Part-Three is split into two ‘phases’ each lasting about 25 minutes
During phase-one the examiner will play the role of a learner with very little or no experience at all of the subject that you are asked to teach. During phase-two the examiner will play the role of a pupil with more experience and prior knowledge of the subject you are asked to teach. You will be assessed on your ability to match your instruction to the level of the pupils portrayed, observe and correct any errors and maintain a safe controlled learning environment.
Developing role play skills takes time and effort for most trainees. For many people, the role play environment is something completely new to them. They feel confused and a little embarrassed. Again, another reason why we prefer our instructor training to be on a one to one basis. The learning environment needs to be comfortable and relaxed for ADI trainees to obtain the maximum benefit from the role play experience. If you don’t feel at ease with the training situation, you won’t learn as much. If you feel uncomfortable with role play when you are one of two or three trainees in the car, your progress will be slower and you may not fully develop the skills needed
For each of the two roles the examiner will choose one of the exercises given below as the basis of the instruction:
Safety precautions on entering the car and explanation of the controls
Moving off and making normal stops
Reversing and reversing into limited openings to the right or left
Turning the vehicles round in the road to face the opposite direction, using forward and reverse gears
Parking close to the kerb, using forward and reverse gears
How to make an emergency stop and practical instruction in the use of mirrors
Approaching and turning corners
Judgement of speed, making progress and general road positions
Dealing with road junctions
Dealing with crossroads
Dealing with pedestrian crossing and giving correct signals in a clear and unmistakable manner
Overtaking, meeting and crossing the path of other road users, allowing adequate clearance.
In assessing your performance, the examiner will take into account:
The method, clarity, adequacy and correctness of instruction given
The observation, analysis and correction of faults committed by the pupil
