Last year, the United States was ranked 33rd on Educational Performance in Reading, 27th in Maths, and 22nd in Science.
In National IQ scores, we are ranked 9th; along with Andorra, Australia, Czech Republic, Denmark, France, Hungary, Latvia, and Spain.
It has been proven that allowing children and teens to sleep in another hour or two before going to school improves their test scores and overall performance in school. If we could take advantage of this information we have to increase our educational ranking, why wouldn't we?
