It's not though.
Give ten kids from the same class a self study online course and give another ten a private tutor, and they won't see the same score distribution. Where's the signal there?
SAT results don't have a line item that notes the amount of wealth or privilege that went into preparing.
> Immigrant families eligible for reduced price lunch are able to scrounge up the money for these tests.
Some families can't. Other families aren't aware, or aren't interested. But we judge the kids in the family for that.
That said... I don't know how the _new_ system will work at fighting that privilege -- there are still lots of ways for it to disguise itself. But we have to at least acknowledge the issues with the SAT.
But, to me at least, this goes beyond privilege. This is about diversity of skills and diversity of learner profiles and moving away from linear quantification of potential.
