Teaching was a different world then.
Children with significant SEND weren’t in mainstream so mainstream teachers didn’t have children with eg high need ASD/ADHD or significant SEMH needs in their class. We have children needing hoists, PEG feeds and alternative communication systems in our classes. The class teacher is often expected to meet all of their needs alone, plus ensure everyone else is making constant progress in continually adapted lessons tailor-made to individuals.
Children were virtually all toilet trained in mainstream then, so teachers weren’t trying to change nappies, soiled pupils or manage this need with regular reminders, checks, charts, monitoring fluid intake etc
No Ofsted so the pressure of Deep dives, observations, single-word judgement with forced academisation and job losses for a poor result were unheard of.
Curriculum expectations were totally different so teachers weren’t trying to teach an unsuitable curriculum to their class because Michael Gove decided 8 years ago, it would be a great idea to try to recreate a 1950s-style public school classroom across the county.
Funding was organised so that teachers were paid centrally and it didn’t matter what pay grade they were on. Now schools have to sort their own very limited budgets and heads can’t afford to have expensive teachers, so are forced to remove them. This is often done by telling teachers they are out of date and below par and need to go on capability.
It’s impossible to directly compare education now and then and say, ‘well, my teachers didn’t have a TA and didn't moan’.
