Again, as I said above, this age ended with the birth of the comprehensives. For the first time, state schools with non-selective input were expected to send large numbers of kids to uni. Far more kids at comprehensive schools had parents that REALLY CARED. Abusive teachers had nowhere to hide. They could carry on spanking the really bad kids, but where’s the fun in that?
Some districts had so many comprehensives, that they quickly became known as good or bad. The bad ones often carried on the character of the earlier Secondary Modern, and teachers there could continue their ‘games’. Other districts didn’t lose their Grammar, so the earlier principles still applied.
