I often hear from P.D.I's that the briefing MUST be VERY important on the part 3 test. I say this, the briefing has an important place in driving instruction but do you actually believe that the S.E. is more concerned about your briefing than your control and instruction/guidance of the lesson whle the vehicle is on the move?
Think about it, the S.E. and any sensible parent for example would be far more concerned that you get thier young son or daughter back home safely and happy after a driving lesson during which they learned good and safe driving practices
Chill out a little as far as the briefings go, be yourself and explain to the pupil/S.E. what the lesson objectives are and try to get the main points of the subject across, if you miss something then cover it on the move
A good way to think about a briefing is 'how would i do this?' then simply pass on that knowledge to them, forget the word for word acting classes, remember you're a driving instructor not an actor :)
The fault ID, Analysis and Remedy can be thought of as WHAT - WHY - HOW
Lets take a look at a common fault, in this case the SE/pupil has come to you for the first time after quite a few lessons from another driving instructor, you quickly establish by Q and A that he/she is a phase 2 driver and seems to be competent and confident during general driving on a straight road in traffic
You then instruct him/her take the next road on the left, the SE/pupil does a very nice approach and selects the correct speed and gear for the turn but during the turn you notice that the clutch pedal is being kept hard to the floor
Ah hah you think......a chance to use the core competencies to fix this obvious fault
You begin by pointing out the error to her/him, eg, "I noticed that you kept the clutch pedal to the floor while turning that corner"
Well done to the instructor for spotting the fault

You then go on to tell the SE/pupil "not to do that any more because thats coasting and is not a good thing to do"
Ah you think.....thats solved that one, you then instruct him/her take the next road on the left, the SE/pupil does a very nice approach and selects the correct speed and gear for the turn but during the turn you notice that the clutch pedal is STILL being kept hard to the floor
Hmmm....must be the SE/pupils idea of a game because I fixed that, this is not fair and REAL pupils won't do this, the SE just wants me to fail.....must be that damn quota thing......I knew it was true because my learner pass rate is quite good...
Now lets go over that scenario again and handle it slightly differently......
You then instruct him/her take the next road on the left, the SE/pupil does a very nice approach and selects the correct speed and gear for the turn but during the turn you notice that the clutch pedal is being kept hard to the floor
You begin by pointing out the error to her/him, eg, "I noticed that you kept the clutch pedal to the floor while turning that corner"
Well done to the instructor for spotting the fault
You then ASK the SE/pupil "do you know why it is important to bring the clutch up after the gear change and keep it up during the turn around the corner?" if he/she does NOT know this is the time to tell them
The SE/pupil gives you the correct answer
"Well done" you reply "so why do you keep the clutch down like that? you just agreed with me that it's not a safe thing to do?"
"Well I'm frightened of the engine stalling when we go slow like that and i was told not to keep stalling the car by my last instructor" ...........
NOW you have a baseline to work from.........
