Again the SAT has been around since 1926. I have seen no record to this day about the importance of this test until whites could not be given every college admission. So it really can't be all that important.
Is everything about race? If you have to eliminate standarized testing to achieve racial equality in admissions then you're not making a good case for racial equality.
For as long as I remember, the message behind racial equality is that ALL races, colors, and ethnicity were equally capable of success given a level playing field.
You can't get playing field more level than standardized testing.
One thing to consider is that the programs that offer the best prep for SATs are expensive and kids who don't come from families who can afford that are at a disadvantage.
If we are actually going to have racial equality, our schools would be all equal, and they are not. They depend on the tax dollars of the school district, and kids of color usually live in poorer school districts. Kids of color are less likely to be able to pay for the materials or programs to cram for the SAT.
Poverty is an endless cycle that needs to change through education, but the first thing is to make all of our schools equal, across the country, with money and teaching. You can say we throw money at education w/o results, but that isn't true: we can all see how much better schools are in the more affluent areas.
