Tribal firms—those owned by Alaska Native Corporations, Native Hawaiian Organizations, and Indian tribes—are afforded special advantages within the Small Business Administration's (SBA) 8(a) business development program. This book identifies trends in government 8(a) contracting with tribal firms; determines why the government awarded sole-source contracts to tribal 8(a) firms and the methods used to make price determinations; assesses the procuring agencies' oversight of contracts for compliance with subcontracting requirements; and examines SBA's new 8(a) regulation, intended to clarify program rules, to determine how the changes could affect oversight of tribal 8(a) firms.
