The math team our school sends to competitions is about 80% Asian and 80% male. I think that reflects who is best at math competitions. Impartial selection procedures often lead to some groups being underrepresented.

Were impartial selection procedures used to determine who JOINS math team?

I'm sure DD would have been "chosen" for math team if that was done based on grades and standardized test scores, but of course, it's voluntary.

(There's a lot more to this discussion, but come now.)

IIRC, high-ability Asian girls are outscoring high-ability Asian boys on some math measures.
