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 SBAs new 8(a) regulation, intended to clarify program rules, to determine how the changes could affect oversight of tribal 8(a) firms.
