I have a really hard time with art, music, and computer time and even recess being categorized as "nonsense and distractions." If Kyla Ross can attend traditional schooling and go to the Olympics, I don't see why it can't be done. I also have a hard time that there's no "learning challenged" students in this group of athletes. So you only get accommodations for athletic endeavors if you aren't dyslexic or need other additional support. I'm honestly shocked there's a public school system that can afford to get away with this, both from a monetary standpoint and that they haven't been challenged on it. I'm sure there are plenty of high performing athletes that have learning disabilities that would love to take part in the added schedule flexibility. I wouldn't be surprised if this becomes an issue.
That kind of coaching is not available everywhere. I'm also skeptical that there are many elite level gymnasts doing a non-modified school schedule, even though they may attend traditional schools. I know people like to throw out the example of Shawn Johnson. She was basically getting quite a bit of 1:1 coaching from Chow (unless I'm misinformed), so again, not a good example. I have heard so many stories about athletes going early in the morning before school hours, getting permission to leave early, etc.
I don't think art, music, etc are nonsense and distractions by any means, but school is not the only place to get this. At the end of the day, it is up to the family to provide a well-rounded, balanced life for the child.
I'm not really sure what learning disabilities has to do with homeschooling or checking out early?? That is a completely separate issue. Students with learning disabilities should still be able to get IEPs and 504s (accommodations) either way.
