Certification Management Team Secretariat Task Specific Team (CMTS TST)

The Certification Management Team Secretariat (CMTS) establishes Task Specific Teams (TSTs) to address specific issues that require more specialized knowledge and experience and/or demand significant effort. In addition, the CMTS may propose a TST for issues not covered by the scope of any Certification Authority Groups, or which require a direct CMTS follow-up.
