Parents of the thirty million or more boys and girls who take tests in American schools every year will find here a down-to-test-text, reassuring in its manner although ultimately inconclusive. A major section is given over to setting forth the twenty-five tests or series of tests that account for three-fourths or more of all testing in American education: I.Q., standardized achievement tests, occupation interest inventories, college admissions. In each case the scope of the test, of abilities tested, sample questions and answers, the number of children taking the test each year and the test publisher are given. There is also a consideration of career choice, determination of personality problems, whether the child in question can get into college and win a scholarship. Final sections deal more briefly with further testing for professions, jobs, and the armed forces, and the future of testing. Mr. Hawes is definitely a test man, who believes that they help, but while he trusts their general judgment, indicates also that in cases of particular individuals they may be wrong. He has a higher regard for ability than personality tests. His book will provide the worried parent with an arsenal of specific information with which to gauge prospects and the future of his child. It should reach the more ambitious parent.
