Measures of Validity - which has well documented predictive validity

Measures of Validity

A college uses a particular admissions test, which has well documented predictive validity. However, members of a particular minority group tend to score low on this admission test. Some students who have been denied admission based on their test scores are criticizing the school for using a biased test. What steps need to be taken prior to making the conclusion the test is "biased" in the psychometric sense? How can a determination be made regarding whether or not the test is being used in a fair and equitable manner? What other measures of validity would you need as evidence to support the continuation or discontinuation of this admission test?
