A set of standards for Australian general practices has been developed through a 4 year project conducted by The Royal Australian College of General Practitioners. An orderly, iterative process was adopted to ensure comprehensive consultation with general practitioners, other health professionals, consumers and governments. The draft standards were field tested in 199 randomly selected urban and rural practices. Results of this field testing showed that the standards have content validity, that they can be measured reliably and that the practice visit protocol is feasible. The standards are calibrated to define the minimum acceptable features of general practices expected for the mid 1990s. The standards have been adopted by Australian General Practice Accreditation Limited as the basis for a voluntary system of practice accreditation.
