Master Specialist Certifications, intended for experienced technicians, is a series of discipline-specific, hands-on, practical certification exams. They are used to
demonstrate that one not only has the retained knowledge necessary, but can apply their knowledge by passing performance (hands-on) exams.
To qualify for the title of Master Specialist, a technician must have a minimum of 3 years field experience and achieve a passing score on the related written professional level
HVAC Excellence technician certification, (or equivalent NATE, RSES CM, SM, CMS, UA Star), and pass the hands-on performance test. These certifications must be in the
appropriate related area.
Achieving this credential is not a simple task. The professional technician must demonstrate that they can apply what they know.
A written exam indicates whether a technician has retained the knowledge to be competent, but not whether they can apply their knowledge in a real-world, hands-on environment.
It is one thing to know which solder to use, but it is another to be able to create a structurally sound, leak-free solder joint!
The Master Specialist program requires a technician to demonstrate retained knowledge and application of that knowledge.
Hands-on performance certification:
- Assists employers in hiring competent technicians
- Manufacturers in warranty cost reduction
- Provide consumers with assurance of a technician's competency
- Pinpoint current deficiencies in the technical workforce for education program development
- Provide area–specific and nationally-recognized credentialing
The Master Specialist Certification badge, along with its chevrons, identifies technicians who possess the highest levels of competency; they not only possess knowledge, but can also apply it.
Persons who successfully pass these exams are awarded a certificate of achievement, wallet card, patch, and chevron. These certifications are often used to create a working portfolio
of one's training and credentials.
