What CERTI TECHNOLOGIES LTD does
CERTI (Center for Environmental Research and Technology, Inc.) is a US-based online education company that delivers radon measurement, mitigation, and continuing education training to radon professionals. Founded in 1986 by Doug Kladder — a former lead instructor at the EPA Regional Radon Training Center and co-author of the original EPA Radon Mitigation Standards — the company operates from Flemington, New Jersey under parent entities Center for Environmental Research & Technology, Inc. and Colorado Vintage Companies, Inc. All courses carry approvals from the National Radon Proficiency Program (NRPP) and the National Radon Safety Board (NRSB), plus individual state-level approvals across all 50 states and Guam.
The core product is an online learning management system delivering video, audio, live-recorded instruction, course manuals, and interactive quizzes with 24/7 access and no completion deadlines. The course portfolio spans entry-level certification courses (C-101 Measurement at $325, C-102 Mitigation at $475, bundled at $695), a Florida-specific module ($85), 31 continuing education courses priced $35–$235, dedicated exam preparation products, vapor intrusion training approved by the Association of Vapor Intrusion Professionals (AVIP) and the Indoor Environments Association (IEA), and Guam-specific certification courses (C-107, C-108) delivered through Guam Community College. The firm also publishes the consumer DIY book "Protecting Your Home from Radon" ($50, 3rd edition, 25,000+ copies distributed).
Revenue is generated through one-time course purchases on a pay-as-you-go basis, with pricing ranging from $35 for short CE modules to $695 for the entry-level certification bundle. The go-to-market combines self-serve e-commerce with a network of education distributors (Axium Inspections, Green Training USA, National Radon Defense) and device-manufacturer referral partners (Femto-Tech, Rad Elec, Sun Radon, each offering 15% customer discounts). Primary customers are individual radon measurement and mitigation professionals seeking NRPP/NRSB certification; secondary segments include CE-renewal professionals, state-regulated radon professionals, homeowners, and environmental health practitioners. Reported outcomes include a 92% first-attempt certification pass rate, 50,000+ cumulative course enrollments, and 746+ reviews averaging 4.67/5 for the C-101 course.
