Hi,
It is about what is expected of you, so as well as explaining any policies and procedures, relate them back to how you apply this in your everyday routine. Perhaps you have a particular policy that especially relates to your role, such as a SEN policy?
Do you have your own role and responsibilities set out, like your contract? Perhaps you can quote from there and relate to your daily routine to how you meet them?
Working hours, how you seek help/report things this is also something perhaps you have agreed with the employer with?
Did you have an interview, or an induction where all this was explained and then you agreed to it by taking the job, eg. staff conduct, appropriate clothing, body & verbal language, liaising with parents, reporting concerns, challenging discrimination
Hope this helps a little
