Ideally, every student should get a personalized education. In practice, it’s not feasible due to limited resources. So it makes sense to segment kids in 2-3 groups (regular, gifted, special needs) and teach them accordingly. Tests are not perfect but they are a decent objective and non-discriminating criteria to achieve that segmentation.
This program certainly wasn’t perfect, but that’s not the reason it was scrapped. Or else it would have been improved through an iterative process. The reason it was scrapped is leftist progressive dogma. The idea that equity is more important than equality. Jordan Peterson is certainly the best voice on why this equity or equality of outcome is an awful idea.
I am an arab that gew up in a western country and went thru a gifted program at a high school where most students were first generation immigrants. And it’s only today that, looking back, I realize we had a “lot” of Asians in our class, I never saw it like that before, they were just my schoolmates, and they were in the same gifted class as me because they were… gifted.
