Fyi: it’s called post secondary because, I think, UK calls it primary, secondary, and after that is post secondary.
Uk.
Its primary school then secondary school.
Primary school is 6 years “full time” (5/6 years old to 11/12 years old). There are pre-school and “reception” years.
Secondary school is 5 years, with an optional extra 2 years.
Anything beyond secondary school is uni/college/apprenticeship/life
I found secondary school year 6/7 to cover the majority of the foundation of 2 years at Uni (ie, maths, physics, chemistry had a huge amount of repitition before building on it and specialising).

My part of the country “pre-school” is called play school. Not sure if that is a national thing though.
I’ve also never heard this post secondary thing OP is on about.
Post secondary is university, college, community college, etc. I hear it all the time on US News.
