About this exam

The CET (Certified Elevator Technician) designation appears on NAEC's certification roster alongside CAT and QEI, described as an industry-recognized credential that "validate[s] your skills and knowledge, ensuring compliance with industry standards and safety codes." NAEC, founded in 1948 and self-described as the premier association representing the elevator industry, positions certification as a way to demonstrate expertise and dedication and to gain a competitive edge in vertical transportation. The CET is aimed at working elevator technicians and candidates building a career through classroom instruction plus hands-on field training, such as NAEC's apprenticeship pathway. Because NAEC does not publish CET exam specifications on its public site, treat the five-domain outline used by this independent study page - general industry knowledge and safety, systems and components, installation and maintenance practices, codes and standards, and electrical/mechanical troubleshooting - as a study framework, not an official blueprint. Preparation should combine code familiarity, component and wiring diagram reading, maintenance procedure practice, and troubleshooting drills on relay and solid-state control systems. NAEC reports 2,000+ professionals trained through its education and certification initiatives and offers a certification management hub with approved online and in-person continuing education courses for renewal.

What you'll study

Common questions

About CET Elevator preparation

What is the CET credential?

CET stands for Certified Elevator Technician. NAEC lists it with CAT and QEI as an industry-recognized certification program that validates skills and knowledge and supports compliance with industry standards and safety codes. It is distinct from QEI, which is commonly associated with inspection rather than maintenance and repair work.

Who should pursue the CET?

Working elevator technicians and apprentices preparing for journeyman-level responsibility are the natural audience, since the credential is built around installation, maintenance, and troubleshooting competence. Employers may also use it to demonstrate workforce qualification to building owners. Confirm your employer's or jurisdiction's acceptance before enrolling.

What does the exam cover?

NAEC's public pages do not publish a CET content outline. A defensible study plan covers safety and industry knowledge, elevator systems and components, installation and maintenance practices, codes and standards, and electrical and mechanical troubleshooting. Balance your time across all five rather than over-studying the area you already work in daily.

How hard is the CET?

Expect journeyman-level difficulty: questions assume real field vocabulary, component recognition, and code familiarity rather than definitions alone. Candidates with several years of hands-on maintenance experience typically find troubleshooting and component items familiar, while code references and safety requirements reward dedicated review. There is no published pass rate to rely on.

How long is the exam, and what is the format?

NAEC does not state CET question count, time limit, or delivery format on its public site, so no reliable figure can be given here. Ask NAEC directly when you register whether it is computer-based or paper, how many items, and whether any practical component applies. Plan your pacing only after you have that confirmation.

What score do I need to pass, and can I retake it?

Neither the passing score nor the retake policy is published on NAEC's public pages, so treat any specific number you hear secondhand as unverified. Request the candidate handbook or certification agreement at registration; it normally states the cut score, retake waiting period, and any fee for each attempt.

How much does certification cost?

Fees are not listed on the NAEC public site. Cost usually depends on membership status and whether you bundle exam, study materials, and renewal. Contact NAEC for the current fee schedule before budgeting, and ask separately about recertification or continuing education costs so the total is clear.

How long is the certification valid?

The validity period is not stated in NAEC's public material. NAEC does describe a certification management hub and continuing education courses delivered online and in person to help certified professionals meet renewal requirements, which implies periodic recertification. Confirm the exact cycle and required continuing education hours with NAEC.

What is the best study order?

Start with safety and industry knowledge, because those concepts frame everything else. Move to systems and components so you can identify what you are troubleshooting, then installation and maintenance practices, then codes and standards. Finish with integrated troubleshooting scenarios that force you to combine electrical theory, diagrams, and code limits under time pressure.

What are common failure modes?

Candidates most often lose points by memorizing component names without understanding function, skipping code sections they do not encounter on their route, and misreading wiring diagrams under time pressure. Weak electrical fundamentals - relay logic, solid-state controls, meter use - also cost heavily. Practice explaining each system aloud and tracing faults on real diagrams.
