I did a year at school at 14/15 in a school in California.
I loved the fact that there was no “formal”uniform. Most of us wore jeans or shorts and T shirts, whether male or female. I loved it!
We also had mixed age groups within each different class, which meant streaming by attainment/ability rather than age, we also studied the same 6 subjects each day, English and PE were mandatory, maths was only compulsory until a certain level reached. We started school at 7:30am and finished at 2:30pm. Very little truancy and very little behavioural issues.
This was not a private school but a very large co-education “public” school, (totally different meaning to our own public schools here), very sadly, for me, my dearest mama loathed living in California, though myself and DF loved it as much as she loathed it.
So, thanks to her, we relocated back to England and I was sent back to my old girls Secondary modern, uniform and all!
It took me years to “forgive” her! But it was an amazing experience, which I never forgot and was extremely Lucy as back in the early 70’s not many people travelled internationally.
