The school was also divided into forms, which were named by a number and the initial of the form master. The number one was eschewed, so boys started in Form 2. The Fifth and Sixth Forms were divided between lower and upper: the complete form numbering system was Form 2, Form 3, Form 4, Lower Fifth, Upper Fifth, Lower Sixth, Upper Sixth. For the academic year 1945-46 for the only time at the St. Helen's House site there was a three form entry intake, but then starting in the academic year 1946-47 it reverted to its normal two form entry.
