The First Intelligence Tests Were Validated by Showing That

The first intelligence tests were validated by showing that

A) children from wealthier families who did well in school scored higher on the tests than children from poor families who did not do as well in school
B) teachers judgments were wrong because children they characterized as problems did better on the tests than did children who were not problems
C) younger children could pass the same items older children passed thus showing there was no age bias in the tests
D) the tests could identify children who did not do well in school but who had practical intelligence and could solve problems in their environment
