摘要：	The problems of quality assurance in a decentralized I/M program are well-known. As a result, every current decentralized I/M program does some formal periodic audit of licenses stations. However, formal auditing cannot detect certain quality assurance problems. Specifically, while formal auditing can certainly test what station personnel may know, it does not necessarily test what is actually done during inspections and repair. Cover auditing allow I/M program managers to determine what is actually happening in a program. Undercover cars have historically been used in safety programs to gather evidence on stations which may have been flagrantly violating the rules of the program. To be sure, covert auditing may serve this role of I/M as well, but it also serves to encourage comprehensive inspections and proper repairs. In addition, it may be used to gather data on program operations. It is the purpose of the manual to present program approaches and techniques for covert auditing. Issues in both enforcement-related and data-related covert auditing are described. Results of existing covert auditing programs are discussed. Finally, some of the practical issues in program development are investigated, and two model programs (an initial program and mature program) are presented.
