478.This section directs the reader to section 90 for a definition of “disciplinary penalty”. It defines “member of staff” for the purposes of this Chapter as any teacher who works at the school and any other person who, with the authority of the head teacher, has lawful control or charge of pupils at the school. This may include members of the support staff of a school. It would also include unpaid volunteers who are put in charge of pupils (for example on an educational visit). The section also specifies that “possessions”, in relation to a pupil, include any goods over which he appears to have control.
