We don’t need ‘grades.’ Everyone knows that talents and abilities don’t develop at the same rate in different children. …The grade is an administrative device which does violence to the nature of the developmental process. …The fixed education represented by a diploma is a bit of conspicuous waste… We don’t attach an economic or honorific value to education. It has its own value or none at all.
