This is missing #babyschool per the SaconeJoly Brandin the uk we have this:
playgroup/preschool - 2 1/2 - 3 1/2
nursery - 3 - 4
reception - 4 -5
primary school - years 1-6 ages 5-11
high school - 11-16
sixth form 16-18
Preschool and nursery are optional and kids can go straight into reception at 4. I went to both and I really enjoyed going.
After kindergarten, we've got primary school well.. there's four years I guess you're 10/11 at the end of it... then high school, 11-19.
So if you don't go to any kind of daycare, most people will only go to 3 institutions, kindergarten, primary school, high school.
My cousin lives in the US and her girls had been through 4 types of graduations from some type of schooling by age 7. Meanwhile I had at that age only just started at the second place. My parents worked from home so I didn't go to daycare, I started in Kindergarten at 3 years old.
