You might like to read the DT1 document. It gives the rules for SE's to follow for Part 3.

Make sure your lesson plans are up to date, and ready to use

Try to have an early night, the night before so you will wake up feeling refreshed

Make sure you're dressed tidily, and you car is clean inside and out

Arrive on time

Don't forget to take your 'L' plates

Try to be calm, relaxed and focussed;

Be positive and composed;

The Supervising Examiner (SE) will be aware that you will be nervous and tense;

If you do get tense, its because your brain is being starved of oxygen, so take a long deep breath and refresh your thoughts, your not doing a marathon;

Try to remember what you've been taught;

Listen carefully to the SE when he/she's briefing you on the Pre-set (PST) topics;

Be prepared for the SE to be erratic and unpredictable when in learner mode;

You must treat the SE as you would a real learner;

Don't be afraid to ask the SE about their faults;

You must keep control of the lesson. You must not let the SE take control until they are satisfied;

Don't ask the SE to do something, TELL THEM;

Try not to under instruct on phase 1;

Avoid over instructing on phase 2;

Don't be afraid to pull the SE over into the kerb to discuss a point, if it's going to take more than a couple of seconds to explain;

Do use the dual controls or steering if necessary;

You must cover the core competencies - Identification, analysis and remedy;

Don't forget to debrief at the end of each phase;

Be prepared for the SE to ask you 'awkward' questions;

Make sure your answers are correct and not misleading information;

You may find that the SE will try to help to some extent, if you're on the right track.
