On the basis of the Army General Classification test a representative sample of 768 World War II white enlisted men was chosen. These men were administered the Wells Revision (form 5) of Army Alpha examination. The scores of these men are compared with World War I norms. The World War II men have significantly higher scores. While the data presented in this study offer no proof, the writer is inclined to interpret them as indicating that the present population is superior in mental test performance to the population of a generation ago, and that a large proportion of this superiority is a consequence of more and better education for more people.
