Performance Component: Gas Furnace Start-up and Check (50%), and Refrigerant Recovery and System Recharge (50%).
NOCTI and NBS exams assess an individual's end-of-program knowledge and skills in an online proctored proficiency examination format. In addition, some programs administer a NOCTI/NBS performance component test to assess application of skills.
In the lower division baccalaureate/associate degree category, 3 semester hours in HVAC, Refrigeration, General Technology or Mechanical Technology (5/12) (5/17 revalidation) (12/21 revalidation). NOTE: An additional 1-2 credits may be awarded based on successful completion of the Performance Component when given in conjunction with the written proficiency examination.
