Section III analyzes Army data on recruits' school continuance by Alpha level (Table IX, Figures 2-4), tested about 15 years out of school on average. The text adds that had the illiterate group been included, the contrast in high school entry would be at least 30 times as great.

"Of those scoring less than 35 on Alpha, 4 in 100 reported that they had entered high school; of those scoring 155 or better, 92 in 100, or 23 times as many, so reported."
