I'm not sure whether DD was at the "top" of her class (by that I mean absolute number 1) but I knew she was v v bright as her teachers told me at every parents evening.
She was on the top table for every subject (they have colours for each table for each subject according to abilities). She got top marks in her phonics score in year 1, she got top marks in SATS in year 2 and she got top marks in SATS in year 6.
She won prizes for writing and got a piece of work published. Her reports were all As and she was the first person in her year to get her pen license. I know that she was the first as they announced it in assembly.
Now she's at High School and she in top set for all lessons and gets As in most subjects except for PE (obviously gets her sporting ability from me
).
From all this I would assume that she was at least one of the top in Primary school.
I would NEVER EVER tell anyone in RL that she was at the top of her class though. If anyone comments on her abilities I just say that she's "doing well at school".
I still have DD2 at Primary and I know that she ISN'T top of the class.
Every parents evening I get told that she's where she's meant to be. She seems to be on middle range tables for different subjects. Her reports are mostly Bs with a few As. She's very sporty.
I'm immensely proud of both of them.
But yes, parents usually know whereabouts on the scale their child is, although some might be lying. Some are competitive.
