I am 36 years old and attended school as follows;
1st school was Reception/Yr1/Yr2/Yr3.
Middle school was; Yr4/Yr5/Yr6/Yr7.
Secondary school was: Yr8/Yr9/Yr10/Yr11.

My husband is older. His school years were different and was 3rd year / 4th etc.

What was the equivalent of reception year called for him? He can’t remember and I obviously don’t know because I’m just a mere whippersnapper.

When I started school in what would now be reception, it was called 'rising 5'

I’m 29. We had first school R-3. Middle School 4-7 and High school 8-11.
