Colette Holt & Associates was retained by the State of Missouri Office of Administration (“OA”) to perform a study of possible disparities in access to state prime contracting and associated subcontracting opportunities on contracts awarded between July 2007 and June 2013 on the basis of race and gender. They explored whether Minority-Owned Business Enterprises (“MBEs”) and WomanOwned Business Enterprises (“WBEs”), collectively, “M/WBEs”, have equal access to state contracts, and if not, what remedies might be appropriate to redress the barriers created by race or gender discrimination.
