Race-Norming of the General Aptitude Test (GATB)was Viewed as Appropriate

Race-norming of the General Aptitude Test (GATB) was viewed as appropriate by the National Academy of Sciences because

A) the criterion-related validity of the test for African-Americans and Caucasians is represented by different regression lines.
B) the various groups for which data exists are being held to the same standards.
C) African-Americans are more likely than Caucasians to come from disadvantaged backgrounds, and race-norming the test compensates to some degree for that disadvantage.
D) so few minority group members take the test that the net effect of the race-norming would not yield the desired consequence.
