Donald B. Kraybill,  Amish Schools Are Simple - But They Work
The Philadelphia Inquirer, July 1994

Amish teachers care as much if not more about character formation as they do about academic competence. Honesty, obedience, self-denial, hard work, persistence, patience, and responsibility are touted over scientific expertise.

But, nevertheless, Amish performance on aptitude tests related to reading, spelling, word use and arithmetic parallels that of non-Amish pupils in rural elementary schools.
