I don't know about that. I really don't know if they would pass judicial review. All I can say is that it was company written tests that started this college stampede in the first place. The Supreme Court ruled that tests administered by Duke Power Company were racially discriminatory, so companies flocked to the college degree as a subsitute.
They are widely accepted by colleges as being very a reliable predictor of success in college. So?....why wouldn't they predict success on the job? To my knowledge SAT and ACT tests have never been challenged as being racially biased.
Most of the work done in the U.S. doesn't need a college degree. For example, why does the event planner at the Marriott Hotel need a degree? They simply need to be sufficiently literate, numerate, intelligent, and ambitious. SAT and ACT scores are likely very good measures of these qualities.
For nearly all the work done in the U.S. most of what an employee learns is **on the job**!
