Yes they have performed exceptionally academically so top of class / year in academic subjects, possibly considered gifted? My dd's primary has just had a year 6 leavers awards ceremony, there was a big silver cup for this, and the child chosen to receive the award is according to my dd "the smartest person in the whole year and comes top of everything". I recognised the girl who won the award from photos the school put in the end of year newsletter / email, and she's always been top of everything academically since infants. My dd was in a class with her a few times over the years and even back in reception she was very advanced in reading, writing, cursive handwriting, maths, even at that age she was known for being top of everything by the kids and parents. That's continued throughout the rest of primary. I wonder if she's what is seen as gifted, in my day those seriously high achieving children would get moved up a year to challenge them more but I don't think schools do that these days? If it's your child who won the award op then congrats!
