Hi, welcome to the site. You need to use the ones your setting or placement has and then research about them generally in your handbook.
Use the
look inside feature of
this STL level 2 handbook's preview on amazon and search for the words 'behaviour policy' then click the link to page 141 where it explains behaviour, code of conduct, rewards and sanctions, dealing with conflict and inappropriate behaviour, anti-bullying and attendance.
Hope this helps xx
