The Data Quality Committee approves rules 3-4 times per year, and XBRL US Members who participate in the Center for Data Quality and provide filing software to clients must be certified each time new rules are approved by the Committee.

Center for Data Quality software providers earn initial DQC Certification for a release by using resources and a process like the one outlined below, generating results for a version-specific targeted accession list and comparing it to a corresponding XML log to report 10 false-positive error messages.
