Abstract Biodata is a selection device that is often cited for high criterion validity and low adverse impact, yet little research examines the latter point. Further, little is known about whether differential biodata item responding by ethnic group occurs, and if so, whether this impacts ethnic group differences, predictive bias, adverse impact, and criterion validity. Data from 5,242 applicants for a government agency position indicated that elimination of biodata item response options with differential ethnic group selection rates from scoring consideration resulted in a large decrease in ethnic group differences, no predictive bias, less potential adverse impact, and a nonsignificant decrease in criterion validity. Results are compared to a general mental ability measure. Implications and future research directions are discussed.
