Kobrin, Camara, and Milewski (2002) examined the validity of the SAT for college admission decisions in
California and elsewhere in the United States. They found that, in California, SAT I and SAT II both showed
moderate correlations with family income (in the range of .25 to .55 for SAT I and in the range of .21 to .35 for
SAT II) and parental education (in the range of .28 to .58 for SAT I and in the range of .27 to .40 for SAT II).
These findings indicate that SAT scores may be a function, in part, of social class. Predictive effectiveness
of the SAT was similar for different ethnic groups; however, there were important mean differences ander specified here.
