Given the extreme levels of segregation in certain parts of the country (NYC for example has fewer than 5 percent of Black and Latino kindergartners in G&T programs, but higher enrollment for Black and Latino students in third grade) school systems like that one should seriously consider pivoting to prioritizing equality over G&T funding.
Sure, but shouldn't those kids be in an environment where they can practice reading instead of being painstakingly re-taught the alphabet? As you said, it's not all rare.
I was one of those kids, and I was extremely disruptive in class because I couldn't bear to be made to sit and trace the letter "A" for 45 minutes when I was already reading novels at home. When they stuck me in a different class, things got much better for me, and it's not like doing that cost the school board any extra money.
Why does it happen?
