There are pile of problems with this. 1. Testing 12-14 year olds to decide their lot in life is.. well unreliable. Not to mention brutal. 2. In US race card will be played once it is apparent that proportion of people with different ski color that get free education does not line up with demogrphic proportions(political suicide) 3. People WILL game it by hiring tutors to study to test, bribing teachers, teachers will cheat and give out solutions etc. In Netherlands they have what amounts to counter-intelligence apparatus to counter this. Good luck implementing that in all of the States.
