Question 1Section 608 rules
A technician earned Type II certification in 2004. What must they do to keep it valid today?
The passing score for refrigerant certification
The closed-book test passes at 70 percent. On a 25-question section that is 18 right answers. A Type I test taken by mail passes at 84 percent, which is 21 of 25.
| Closed-book pass mark | 70 percent, 18 of 25 |
|---|---|
| Mail-in Type I | 84 percent, 21 of 25 |
| Results | Within 30 days of the test |
| Pass rate | Not published by EPA |
How the score works
Each test has a Core section of 25 questions and 25 for each type you take. A Universal test is 100 questions. At 70 percent, 18 of 25 passes and 17 does not, since 17 of 25 is 68 percent.
Universal can be taken all at once, or built up by passing the Type I, Type II and Type III tests separately.
Is there a published pass rate?
No. EPA approves the organizations that give the test and sets the pass mark, but it publishes no pass rate or candidate numbers. Our free tests show your share right in each section beside the 70 percent mark instead.
After you pass
The certifying organization sends your result and a wallet card within 30 days. EPA does not issue cards. The certification does not expire, and you keep a copy at your place of business.
