Under New Jersey's Enhanced Inspection and Maintenance (I/M) program, any person or facility shall not perform emission-related repairs for compensation of any kind, unless the repairs are made by, or under the supervision of, a certified ERT employed by the facility. The State has established the Emission Technician Education Program (ETEP), which identifies the requirements needed to become a certified ERT in New Jersey. Recertification is required every 5 years.
The following are required for NJ ERT Certification:
• ASE A6 – Electrical/Electronics
• ASE A8 – Engine Performance
• ASE L1 – Advanced Engine Performance
• Completion of free online NJ-CERT Course
The NJ-CERT Course is a course on the rules and regulations of the Enhanced I/M program in New Jersey, the air quality issues in the State, and the reasons why the I/M program is required. The course covers topics such as what vehicles are inspected and what tests they receive. It also covers special repair topics on tampering, readiness and communications, known repair issues, emissions warranties, and aftermarket catalytic converters. In addition, it provides repair resources, customer service tips, and program contact phone numbers.
The NJ-CERT Course is presented below. Please follow the instructions in each section below to take the course and assessment. Even if you are not currently due to re-certify or take the course, the Modules and Supplemental Materials provide a wealth of information and are available for your reference at any time!
