 In this case, slipperings were carried out as a formal ceremony in the same way as canings at other schools, i.e.the student would be summoned to the private office of the Head Teacher (principal) or Deputy Head or of a senior teacher of the same gender as the student.An example of a school that opted for the slipper as its formal disciplinary implement was Litherland High School in Liverpool, a mixed-sex school, although the policy there was that only boys could receive corporal discipline.
