An intelligence test measures a person's ability to solve different kinds of problems. There are many kinds of intelligence tests. The tests that are sometimes given in schools are called Stanford－Binet I. Q. tests. They were first developed in 1905 by a French psychologist named Alfred Binet and later revised(修訂) for use on children in the United States by psychologists at Stanford University.
Binet had observed that on the average a 10－year－old learns more quickly and can solve more difficult problems than a 9－year－old; an 11－year－old learns more quickly than a 10－year－old, and so on. As a rule a child's intelligence tends to increase year by year. Therefore Binet arranged his tests by age levels：the first problems in any test can be solved by all children of the age level being tested; the problems become more and more difficult until few, if any, children of that age can solve them.
After a child has completed a Stanford－Binet test, the psychologist figures out the score and then compares it with the average score of other children of the same age. If a child solves the same number of problems as the average child of the same age solves, his I. Q. will be 100．If he solves more problems, his I. Q. will be more than 100．If he solves fewer, it will be less than 100．By comparing a child's score in this test with his score on an earlier one, the psychologist can tell how fast the child's abilities are growing in relation to his age.
