"The Theory of Constraints International Certification Organization (TOCICO) is an independent not-for-profit incorporated society that sets exams to ensure a consistent standard of competence"
Also exist lot of business organizations (official), who provide support on implementing TOC best practices, and sure, non-formal fan-clubs and lists of books and lists of other support files (learning software, accounting software).
