OBJECTIVE： To provide unified standard for assessing the comprehensive ability of food and drug inspection and testing institutions in Guangxi Zhuang autonomous region. METHODS： The comprehensive ability evaluation index system for food and drug inspection and testing institutions in Guangxi Zhuang autonomous region was drafted by literature review. Indexes of the evaluation index system were determined by Delphi expert consultation， and the weights were calculated by analytic hierarchy process （AHP）. RESULTS： Literature review and expert consultation had constructed the comprehensive ability evaluation index system for food and drug inspection and testing institutions in Guangxi Zhuang autonomous region， including 6 first-level indexes， 16 second-level indexes and 35 third-level indexes. AHP had determined the weights of indexes at all levels， and the weights of the 6 first-level indexes as basic conditions， management system， testing ability， work performance， scientific research and satisfaction degree， were respectively 0.189 8， 0.123 3， 0.228 0， 0.191 5， 0.155 1 and 0.112 4， in which testing ability held the highest weight. CONCLUSIONS： A set of scientific and suitable evaluating index system for food and drug inspection and testing institutions in Guangxi Zhuang autonomous region has been constructed， and the weights of indexes at all levels have been determined， which can provide clear and unified standard for conducting comprehensive ability system evaluation in each inspection and testing institution in Guangxi Zhuang autonomous region.
