Ellwood Cubberley, dean of the School of Education at Stanford University, writes several books challenging the way in which schools are run. Beyond urging greater administrative efficiency, he is one of the first educational reformers to push for the now more common (and controversial) practice of tracking students according to ability. He said: “We should give up the exceedingly democratic idea that all are equal…one bright child may easily be worth more to the national life than thousands of those of low mentality.”
