Part 3: Driving Instruction School: Become A Driving Instructor
ADI Part 3 Test: Instruction Ability
About the Part 3 Test
The Part Three exam to become a Driving Instructor requires you to give 2 half hour lessons on subjects chosen by the examiner.
- In both parts, the Examiner will play the role of the pupil and you will be the Driving Instructor:
- During the first half hour lesson, the Examiner will play the role of a novice driver.
- For the second half hour lesson, the Examiner will play the roll of a pupil who is nearly at test standard.
- During the Part 3 Test, you are being tested on your ability to instruct and deliver a lesson.
The information below is taken from the Transport Office, Becoming a Driving Instructor web pages.
The object of this test is to assess the quality of your instruction and your ability to pass your knowledge on to pupils. The test is in two parts, each of which lasts about half an hour. You must pass both parts on the same test.
You will be asked to demonstrate your knowledge and ability by giving practical driving instruction to the examiner who will first take on the role of a pupil who is a beginner, or a learner driver with limited driving knowledge, and then a pupil who is about test standard. The examiner will explain everything to you at the time.
The exercises
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 vehicle 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 positioning
- dealing with road junctions
- dealing with crossroads
- dealing with pedestrian crossings and giving correct signals in a clear and unmistakable manner
- overtaking, meeting and crossing the path of other road users, allowing adequate clearance
The instruction you give should be tailored to the time available and to the standard of the ‘pupil’ being role-played by the examiner. You will probably find it helpful to establish the depth of the ‘pupil’s’ knowledge in each phase, by asking questions and observing the ‘pupil’s’ performance as you would with a real pupil you had not taught before.
How will I be assessed?
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
- your general manner
You will be expected to maintain control of the lesson, be patient and tactful and give encouragement to the ‘pupil’ at all times. What is assessed is the relevance of the instruction for the ability of the pupil and to the particular conditions on the road on the day of the test.
