I'm not surprised that Black US kids don't perform as well as white US kids, or as well as Nigerian, Ghanaian, Kenyan, or Caribbean kids. I'm surprised that any Black kids make it through this hellish gauntlet at all.
When you look at how much the US pays to educate each student, and how poorly it does at Black educational achievement, it's clear that the US is the worst country in the world at educating Black students, by far. Because racism. No one spends more to achieve less.
Once you understand white US history instead of Black history, you'll understand why the following interventions will do much more to improve US Black educational achievement than most of the nonsense we're trying today:
• Bail reform
• Fire racist teachers, including the Bill Cosbys
• Retain anti-racist Black, white, AAPI, Latinx teachers
• Get rid of school cops
• Provide all students free lunch. And breakfast. And afternoon snack.
• Transfer police budget to school budget. Bring back art.
