If the school you are instructing at is going to "do the right thing" and you are being supervised by the senior instructor on duty, then he/she should be briefing you BEFORE THE STUDENT ARRIVES, PRIVATELY, to ensure that your first day butterflies are well and truly settled. He/she should also be available at the end of the sessiion to sit in on your de-brief to the student with an explanation to the student that as this your first day working for the company that the you have covered all the requirements for the lesson. This instills confidence in the student that he/she is being looked after by the company and that there is a committment to provide quality instruction to all customers.Smile and show that you have every confidence in your own abilities, enjoy yourself and Good Luck!
