He passed all his classes just fine, but he could have done much better if he hadn't missed all those day and the teachers said so. But, he will never forget that Easter trip and competing with kids from around the world, so that was certainly a lifetime memory. Was the (educational) cost worth it in hindsight? We'll see when he starts applying for universities, I guess.
I just want to push back gently on this last part. (I don't think this is off topic, we are talking about taking kids out of school and its impact on education. This is about the long-term impact.)
First I want to say that I agree with all the rest of your post. It is such a challenge and there are so many competing factors that seem to be at odds with each other, and it sounds like you did the best you could with a difficult and unexpected circumstance and made it through.
But this notion that applications to college/university is the ultimate arbiter of what worked and what didn't in one's child's life is something I don't agree with. Maybe it was just an offhand comment on your part or not something you agree with personally. I don't mean to single you out. In our household this idea that college applications will tell us about the success of 18 years of parenting has a lot of support. Sometimes my wife, always (it seems) parents of my sons' friends, often my sons themselves, and yes a voice in my own head. "If they don't do X, and Y, and Z just right, they won't get into a good enough college."
Quotes from my sons (ages 16 and 17) are the most representative:
"My friend's Mom said she (the friend) had to take 7 AP courses and all honors otherwise throughout High School in order to get into 'a good school.'"
"Should I take this course/join this club/run for this office so that it will look good on my college application?
"I can't fit AP Spanish 5 into my schedule, but I really like Spanish, but the only class that fits is regular (not even Honors!) Spanish 5. Should I drop Spanish altogether?"
"Is my GPA/SAT score high enough?"
"Which IVY LEAGUE school should I try to get into?"
I have always (for years) pushed back gently but firmly against all of this. "Don't worry about what your college application will look like!" "Do what you are passionate about and do it well, the rest will work itself out." "Any one of hundreds of colleges can give you a good education if it is a good fit for what you want to do, it doesn't have to be IVY."
Well, now my oldest is about to apply to colleges, so I guess I, like you will find out if I was right or wrong, but I HOPE that whatever colleges he does or doesn't get into, he'll be a happy, confident, capable person, and that what college he goes to will not define him.
As always with such an individual subject, I'm not trying to comment on what is right for any other family; I'm just sharing the events in mine in the hopes that some will find it useful or at least amusing.
