The basic goal of the technician training and certi cation program is to teach technicians how to properly recover and recycle refrigerant, and why it must be done to protect the environment.  \nSEE INSTRUCTIONS FOR TAKING TEST AND OTHER INFORMATION ON INSIDE FRONT COVER.  \n Do not mix up tests or exchange tests with other individuals at your place of business. All tests are coded with names matching assigned numbers.  \n Please review your test upon completion. Any questions marked with more than one answer will be scored as incorrect.

Following are the steps* necessary for you to complete the prescribed training:  \n* The following instructions apply to technicians taking the MACS training course by mail or online. Those participating in a classroom program should follow the instructions of their trainer/proctor. Tests given in a classroom setting must be closed-book tests. The required score for passing closed-book tests is lower than that required for passing the open-book test.  \n1. Read the instruction manual that came with your recovery/recycling service equipment (and review the training video, if provided) . Then read this manual cover to cover. Re-read as necessary to gain full comprehension of the material presented.  \n2. Take the test. The test is an untimed,“open-book” test, so you may refer to the training manual as often as necessary to research answers to the questions posed. (Note, however, that you must correctly answer a minimum of 21 of the  \n25 questions to earn certi cation.) You must complete the test by yourself, without assistance from anyone, and submit it for scoring. (See 4 below.)  \n3. Complete and sign the “Identi cation and Statement of Testing Conditions” block on your test.  \nNote: A reprint charge will be incurred if information provided is not legible.  \n4. Mail your test in the self-addressed envelope provided to: MACS-EIF, P.O. Box 88, Lansdale, PA 19446, or submit online.  \n5. MACS-EIF will advise MACS of your test results.  \n6. MACS will advise you of your score and, providing that you have attained a passing score, will issue a certi cate and a wallet-sized I.D. card, indicating that you have successfully completed this MACS certi cation training program.  \nEnclosed:  \n Test with identi cation information to be mailed to scoring facility.  \n Self-addressed return envelope (MACS-EIF) .  \nImportant-Please note: Tests must be returned for scoring within 90 days of the date they are issued. MACS assumes no responsibility for tests submitted for scoring after this 90-day period.
