Test score disparity by income

Recent research has linked high family incomes to higher mean scores. Test score data from California has shown that test-takers with family incomes of less than $20,000 a year had a mean score of 1310 while test-takers with family incomes of over $200,000 had a mean score of 1715, a difference of 405 points. One calculation has shown a 40-point average score increase for every additional $20,000 in income. The College Board President Gaston Caperton has responded by discouraging students from taking SAT Prep Courses in favor of hard work in tough courses in school.
