EPA page last updated 15 July 2026. States plainly that Section 608 Technician Certification credentials do not expire, and that a Core test taken open book cannot count toward Universal certification.

EPA's own topic list for the Core, Type I, Type II and Type III tests. Used for the topic hubs. Note EPA's page labels Type II as High-Pressure, while 82.161(a)(1)(ii) covers medium-, high- and very high-pressure appliances; the regulation governs.

The list of EPA-approved certifying organisations. Fees and time limits are set by each programme, not by EPA, so this page is linked rather than restated.

Retrieved through the eCFR versioner API at title 40 issue date 2026-09-17. Carries the technician certification rule at 82.161, the appliance definitions at 82.152, the venting prohibition at 82.154, the evacuation levels in Table 1 at 82.156, and the leak rates at 82.157.

The exam blueprint is written into federal regulation here. Section d fixes the test content: 25 items from Group I plus 25 from each relevant technical Group, so a Type test is 50 items and Universal is 100. Section e fixes the passing score at 70 percent, and 84 percent for a mail-in Type I test.
