C3 for Employees


NTC Core Competency Certification for Employees

Core Competency is a knowledge-based certification program. Certification is based on the knowledge an individual has, not on the years of experience. Core Competency Certification (C3) does not have any prerequisites or experience requirements.

As an employee, C3 can serve as a proof of your technical competency in different low voltage system areas.

About the Exam

Open Book Exam

You are encouraged to use any books that you prefer. Online searches for information is permitted. There are several different questions relating to products in the industry. Where a specific product is part of the question, the PDF installation manual for that product is available in the test for you to review.

Knowledge-Based Exam

The exams are not intended to evaluate a person’s ability to do field work. Certification is based on the knowledge an individual has, not the years of experience. The knowledge to successfully pass each level may have obtained by study, experience, on the job training, classes, or any number of ways.
