The Service-Disabled Veteran-Owned Small Business (SDVOSB) program is intended to provide federal contracting opportunities to qualified firms. In fiscal year 2007, the Small Business Administration (SBA) reported $4 billion in governmentwide sole source and set aside SDVOSB contract awards. Given the amount of federal contract dollars being awarded to SDVOSB firms, GAO was asked to determine (1) whether cases of fraud and abuse exist within the SDVOSB program, and (2) whether the program has effective fraud-prevention controls in place. To identify whether cases exist, GAO reviewed SDVOSB contract awards and protests since 2003, and complaints sent to our fraud hotline. GAO defined a case as one or more affiliated firms who were awarded one or more SDVOSB contracts. To assess fraud-prevention controls, GAO reviewed laws and regulations and conducted interviews with SBA and Department of Veterans Affairs (VA) officials. GAO did not attempt to project the extent of fraud and abuse in the program. Congress should consider providing VA authority and resources to expand its SDVOSB
