CGCT (Certified Grill Cleaning Technician) is Level I. It verifies competence in professional grill cleaning practices — safety considerations, inspection awareness, sanitation principles, and cleaning-related service decisions. The primary single-person path is the $499 test-out.
CAGST (Certified Advanced Grill Service Technician) is the advanced add-on. It covers diagnostics, mechanical repair, parts replacement, and gas safety fundamentals. You must hold active CGCT first. Standard CAGST eligibility is $299 (published term). After you earn CGCT, purchase CAGST from your account checkout. There is no separate public CAGST landing page yet — plan on Get certified, then the account path.
