Assign Exam Codes

Give a code to any employee or potential employee that needs to take an exam. Assign the student a specific low voltage system and level to test into. 

Employee Takes Exam

The employee or potential employee logs into or creates a free NTC account and uses the code to “purchase” the exam level assigned. The exam is taken within 7 days of using the code.


Certificate is Awarded

The employee or potential employee is awarded a certificate when they pass the certificaiton exam. The certificate is only awarded if the test taker passes the exam. 

About the Exam

Open Book Exam

Test takers are encouraged to use any books that they prefer. Online searches for information is permitted. There are several different products by common manufacturers in the industry, and where a specific product is part of the question, the PDF installation manual for that product is available for the test taker 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 on 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. 

Choosing a Level

NTC’s C3 certification exams can be taken in any order. It’s not necessary to take each level. If a test taker demonstrates or claims knowledge appropriate for Level 3, he or she should take the Level 3 exam without needing to take Levels 1 or 2.
