The DCs went to a school where they didn't maintain a G&T register or differentiate within classes - no tables with different groups working on different levels, etc. Throughout the primary years all the children had a folder in their desks labelled 'Never Done Work' -- when they were finished their class assignments they could open their folder and work on whatever piqued their interest in the folder, which the teacher stocked with puzzles, writing and drawing prompts, brain teasers, mazes, maps, word problems in maths, etc. They handed in the extra work with the class assignment.
The thinking seemed to be to keep students engaged in challenging themselves and constantly engaged in some form of learning at their own pace without singling anyone out for special attention. The teachers encouraged the children to read a lot at home. They were always happy to suggest sites for extra maths or other enrichment to do at home too. The DCs did standardised tests every two years and the two oldest DDs scored in the 99th percentile for all subjects tested each time. DS scored quite well but his results varied. DD3 and DD4 also had varied results with DD3 doing better overall than DD4.
DD1 read at three, got As all through and graduated second in her class in elementary and got one B and the rest As in high school, plus was a National Merit Scholarship finalist. Shone in all subjects. She ended up going to an Ivy League university and graduating with honours, going straight to a job. She was a party animal from age 14, very into fashion, always very involved with friends. Had a part time job and summer job and did lots of babysitting all through school. She also did sports in school -- swimming, water polo and badminton. Very gung ho and fearless about everything she decided to do. Had the odd brush with danger but got away with it. Had a boyfriend I couldn't stand in her late teen years but she dumped him. Current boyfriend is much nicer. I sent her to summer camps for G&T children where she played chess for six hours a day (her choice). Every teacher she ever had told me she was gifted.
DS read at 4, had a very patchy career in elementary and HS, didn't do much homework but never got into trouble, flew under the radar because he is quiet, got a lot of Cs and 'DS is an exceptionally bright boy and could do much better' remarks on reports, got into a so-so university and suddenly discovered heretofore untapped ambition and ability to do the assigned work and hand it in on time. Did exceptionally well in his first year and transferred to a great US state university where he is on track to eventually do medicine (if he can keep up the work for another 150 years, lol). I want to snog the academic adviser who suggested medicine to him. He played football in school and socialised regularly. He didn't shine at football but went to all the practices and did the weightlifting in the offseason. He played organised baseball all through his childhood and basketball in elementary school, alongside a group of flashy and brilliant classmates one of whom is now playing at college level. Their team had a 56-3 winning record in their final season. DS scored four points and played about 5 minutes per game.
He and his friends used to play video games and nerf guns, cinnamon challenge idiocy etc., and probably still do when they have a chance to get together. Set up his own gardening and odd job money earner in secondary and had a summer job this summer. Much more inclined to dither about decisions than DD1 and to doubt his ability and compare himself negatively with others, but now seems set on a course and happy and determined about it.
DD2 read at 3, has yet to get a grade below A and will be applying to very selective US universities this winter with a high hope of getting accepted by at least one. She is a very straight down the line academic whiz kid. She is also very sociable, loves fashion, loves going out with friends but not the diehard partier that DD1 was thank goodness, babysits and is loved by small children. She has held down a part time job all school year on weekends since turning 16 and had a full time summer job this summer. Plays badminton and played soccer, basketball and volleyball in elementary not a star but loved being on a team. Joined every club available in elementary including drama and the school band. Left the band after a year didn't like being the only girl in her year doing it. She went to a Harry Potter summer camp for HP geeks. Again, all her teachers have told me she was gifted.
DD3 sorted herself out gradually and by age 13 was getting straight As. I made her do maths at home when it became clear to me that her teacher wasn't much use. She went from being a quiet, medium achiever to really blossoming over the course of two years (12 to 14). She now loves acting and has decided she really 'gets' maths. It has sort of set her free. She would probably not have shone enough to get on a G&T register at a younger age but I think she has more potential than any of the others. She hasn't found her inner party girl yet at age 14, and tends to overthink all things social to some extent. Thinks long and hard before joining anything also, but makes good decisions about what is right for her, though initially getting her to do the extra maths was an uphill struggle. Played volleyball in elementary and enjoyed it in her own way. Refused to go to summer camp. I think DD3 baffled most of her teachers. She very much played her own game within her comfort zone.
DD4 definitely wouldn't make a G&T register and will take a lot of extra work and a change of attitude to get to be an all round student. Right now she will only work at things she has had positive feedback about in the past, and even in those areas her approach is 'get homework done with the minimum effort and minimum time spent and move on with your life'. Luckily for all of us she likes reading she is incredibly stubborn and I wouldn't be able to get her to do it if she didn't want to. She is loved by all her friends, who are all only children strangely enough. Plays basketball and volleyball. Values friendships over competition so the social end of school is more important to her than the academic. When she was 8 she was getting horrible grades and was referred for testing to see if she needed academic support. The test reports came back and her teacher said, 'The little minx she got over 90% in everything' . So we will see...I actually have no idea how she will turn out.
Apart from DD3 to some extent (in maths) and DD4 (whom I have yet to grapple with) I have let them organise their own lives and have not had a curfew or limited activities except for getting DS to do his homework in the kitchen. As long as they were able to stay on top of their work they could do as they pleased socially and in sports. Their schools encouraged the concept of continuous learning and the American GPA system encouraged consistent effort and responsibility. I always praised effort and good habits and not results. I think playing sports was very good for them all as they were by no means stars.
They all found aspects of elementary school very boring, especially the long revision weeks at the start of each year in maths, and those who were reading at 3 and 4 found phonics boring -- however there was plenty besides reading to learn at age 5 and 6. Lots of social/emotional stuff, and they kept at the reading at home.
High school was appropriately challenging due to the streaming and the fact that class composition could be very flexible so the idea of going ahead a year didn't matter; students of different ages were in different classes. You could be sitting beside an 18 year old in Algebra or a 14 year old in Calculus. In the sets they ended up in there were lots and lots of really, really bright students -- the sort who got into MIT and other exceptionally good mathsy places for instance, and a group who had to choose among multiple offers of places from the Ivy League schools they applied to. The teachers pushed them hard. For DD1 and DD2 it was bliss.
I don't count DS really in this reckoning as he paid as little attention to it all as he could get away with and has really only come into his own in the last year.
