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 Blacks and Whites is represented by different regression lines.
B) Blacks and Whites are being held to the same standards.
C) Blacks are more likely than Whites 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 was deemed inconsequential.
