 There was a complete structure of Prefects, at the summit two head boys and two head girls, then headmasters/senior prefects, prefects, sub-prefects, and TSPs [Temporary Sub Prefects].This separate organisation was particularly called upon when teaching staff took the decision to stop monitoring the substantial play-grounds, in the sometimes turbulent mix of social classes, religious and ethnic origins, and the heady mix of boy and girl in the 1960s.Mr Williams, in the mid-1960s, one of two deputy heads, was required to dispense summary justice on boys presented by Prefects.
