I have a very high ability 14 year old dd who competes at the top end of national at her chosen sport.
She is very settled in a state school.
I actually really like the fact that she gets the “normal teenage life” from school. She has a nice group of friends, she worries about her science test, she thinks the history teacher is a bit mad and…. there is a boy that she goes purple whenever his name is mentioned (not sure she has ever got as far as speaking to him but there is something there…..)
Her sport is getting very serious and very exciting / scary very fast. And if she carries on at her current level it will only get more so.
She also gets a lot educationally from school that we could never give her ourselves. She is currently doing a music module. 2 hours a week of music for about 3 months. Dh and I are not musical and she doesn’t play a musical instrument (too busy doing more sports than Katerina Johnson-Thompson!) so it seemed a total waste of time. But it turns out that she is a little bit musical. They are doing composition and she is able to hear the music in her head (or something - I don’t get it!) It is not something that she can explore now (no time!) but one day, maybe, it is something that she now knows that she likes and can come back to. She’s also really enjoyed Product Design - a GCSE I barely knew existed and would have hated.
The one thing that makes me a bit sad is that she hasn’t really been able to engage with the gifted programme. (Our city runs a big city wide thing for the top few ability wise including lectures, workshops, summer schools and extra GCSEs.) But nearly all of them clash with one training session or other. But you can’t have everything. And she has a lot.
If you take your dd out of school to focus on STEM, music and sport then she will miss out on discovering that she has a natural French accent or that she is intrigued by WW2. And that seems a real shame.
