Boys score as well as or better than girls on most standardized tests. So why is it that girls are far more likely to get good grades, take advanced classes, or attend college?
A study released last week in The Journal of Human Resources provides an important answer. When teachers determine grades, they take good behavior into account and this begins as early as kindergarten. Girls, as a rule, are far better behaved than boys. The research analyzed data from more than 5,800 students from kindergarten through fifth grade and found that boys across all racial groups and in all major subject areas received lower grades than their test scores would have predicted.
