These types of teachers existed then, as they do now.
Back then teachers didn’t have to be qualified, I think compulsory degree qualification came in the 70s. Classroom assistants require none, yes they are popular now, but we never had them.
I took my granddaughter to school this morning, In pouring rain, pupils were made to remain in the playground whilst the teachers huddled in the dry staff room until the magic hour of 9.00 am, Then miss, whoever came out looking like she’d been dragged out of bed, shouting an bawling, hurry in dont you know its raining?
