When our oldest was entering 7th grade he was put into a lower level math class than his ability would suggest. Guidance said they couldn’t change it. We talked with the teacher and it had been done so my boy could help a Down’s Syndrome boy he’d been with since K. Apparently he was one of the only ones with enough patience and compassion to truly include the boy in the various school activities and they wanted to keep them together.
That was fine with us for the younger grades - and sort of fine for middle school upper grades, but it would mean my guy couldn’t get into the math classes he would need to be in for the best foundation for college. We wanted him in the highest level math class (all As in math - and in every other class for that matter), so we went to talk with the Principal. We told him our son was likely to have higher aspirations and would need higher level math in high school. This is what we were told (though over the years, the wording isn’t necessarily verbatim - the meaning remains the same):
“Public school isn’t here to help the advanced student. It’s here to help the average students, and around here the average student goes to cc, joins the military, or works for (insert company name). Then the state requires we help those below average, so we do. The advanced children will do fine no matter where they end up. You don’t have to worry.”
We fussed a bit more and got my lad into that class, but by 9th grade we pulled all three of ours out to homeschool them. They were starting 9th, 7th, and 5th respectively. We supplemented with a few cc classes at the cc during high school.
My youngest returned to public school for his high school years and everyone there considered him a genius. The four years of high school were telling though. Even he will tell you his education would have been better if he had stayed homeschooling, but to him, academics aren’t his priority. He went to college and graduated just fine, but now he’s my Permaculture Farmer. He’s showed me the Naturalist section of Multiple Intelligences is real TBH. He’s been that way since toddlerhood.
But I digress. I work in the high school. Once I was talking with one of my friends who teaches 8th grade English and she told me she was upset because the Powers That Be required her to use a 4th grade level book to read in class across all of her classes. Why? Because not all students were up to reading at an 8th grade level and they didn’t want them left behind. What about her students who were already reading at a 12th grade level? Don’t worry about them. They’ll be fine.
I recall an incident where we (teachers - as part of our school day) were helping all students get ready for their state English test. I was to assist my group with synonyms and antonyms. I quickly found out every single one of them knew what a synonym and antonym was. Where they were stuck was knowing the words - words like tedious and porthole were foreign to them. Maybe, just maybe, they’d have recognized far more words if they had been reading up to grade level by 8th grade?
Fortunately, as I said, our school has improved some since those days. Keystones help. New Admin with a different view has helped. We’re not up to the level of schools talked about on here, but there’s definite improvement. I hope your school can improve some too.
