Accreditation Data System (ADS) is a web-based software system that contains critical accreditation data for all sponsoring institutions and programs. This system is used to collect and organize information for accreditation purposes, while serving as a means of communication between programs and the ACGME. 

ADS includes the case log system and the resident/fellow and faculty surveys. ADS can be used to schedule site visits and site reports to be sent to the review committees, as well as by programs or sponsoring institutions to evaluate site visitors.
