I think both the primary and junior high schools I attended would have be in special measures these days.
The primary school taught me to read, write and calculate. We didn't have a playing field so rarely did PE (instant fail now because of 2+ hours requirement). Mornings were spent learning and afternoons were used for art and playing. Not planned structured learning play... just children playing in the home corner or building stuff. We didn't have a lot of equipment. The teacher used this time to teach reading.
I went to an experimental junior high. It was the first year of the comprehensive system. We were taught in a school that had been a secondary modern the previous year and the staff used all the facilities to give us a range of learning experiences that Year 5 and 6 children never get these days. I did woodwork, metalwork, technical drawing, masses of music, needlework, cooking as well as more academic subjects. The only subjects we did every day were maths and English although sometimes we had general knowledge quizzes because the teachers thought we needed a breadth of knowledge. The teachers found out what talents the children had such as music or sport. I was musical and it was encouraged and nurtured. A friend was artistic so was given extra time with the Art teacher. We had a biology lab with real animals in it. No health and safety issues. If you got bitten (like I did by a crazed hamster) then it was your own fault and you simply rinsed the blood off under the tap lol.
Neither school would have passed safeguarding guidelines. I didn't do a formal test in the three years I was at junior high. But I received a broad education which put in place the skills I needed to learn and continue learning through my life.
