The present report, on the other hand, demonstrates how the adverse ipmact of written tests can be reduced by correcting for the degree to which a job applicant had been educationally and/or economically disadvantaged or deprived. A measure of disadvantagedness containing nine items was internally and externally validated with 11,931 applicants for a nationwide, examination. Internal validation was demonstrated by a factor analysis that yielded two factors. External validation was based on the relationships of scores on the two factors with other variables: minority status, test performance, and educational level; each assumed relationship was confirmed. A composite measure of the two factor scores, called D, had a point biserial correlation of -.31 with passing the test and .54 with minority status. The adverse impact of the test was substantially reduced by partialling D out of test performance. It was also demonstrated that partialling D out of test performance would not necessarily reduce the validity of the test, and could actually improve it.
