I have children in years 6, 8 and 10. I think all of them have suffered through their schooling with covid, strikes and a plethora of supply teachers.
I also know that sen provision is nowhere near fit for purpose because the funding simply isn't enough to support every child who needs it effectively. It really is lip service in most mainstream schools.
Until the current year 9 cohort finish secondary education, I think we will continue to see evidence of 'covid cohort'. In my experience they are less able to attend to independent learning, they are more likely to be passive but combative when challenged. They are the most likely to refuse to help themselves.
My eldest only really missed out on the social side of year 7 due to bubbles. She still did ks2 sats in year 6, had her transition and end of term celebrations. She missed a planned secondary school trip due to covid restrictions but it wasn't the end of the world.
My year 8 conversely is far less affected than the year 9's. He missed out on transition and didn't sit SATS but that was it really. He still got the important aspects of his education done, did the residential trips and by the summer the pupils were still able to have their end of year celebrations.
Years 6 and 7 have more or less had normality in their formative years pre secondary school and anyone else is young enough that gaps can be filled with dedication and effort, from parents as much as school.
