Minority and majority groups were administered a special quantitative section of the Admission Test for Graduate Study in Business (ATGSB) under varying time conditions to determine if increasing the time allotted for the test would eliminate any bias which may exist due to an irrelevant speed factor. By a commonly employed definition the special section was found to be moderately speeded for all candidates under normal conditions. Neither the main effects due to time conditions nor the interaction between the ethnic and time factor reached significant levels suggesting that increasing the time per item does not reduce any bias which may exist in the test. Although a substantial proportion of minority group scores fell at or below the chance level, these scores appeared to retain fairly high levels of reliability. (Author) (24pp.)
