What Is CAT Certification?

What CAT Certification Actually Is

CAT stands for Certified Accessibility and Private Residence Lift Technician, a credential built specifically for technicians who install, maintain, and repair vertical platform lifts, inclined platform lifts, inclined stairway chairlifts, and private residence elevators. It is not a general handyman qualification, and it is not the same as certifications from unrelated industries that happen to share the same three-letter abbreviation. If you found this page while researching a different "CAT" credential, this article - and this entire site - is exclusively about the accessibility and private residence lift version.

The credential was introduced in late 2003 as a companion to the National Association of Elevator Contractors' existing Certified Elevator Technician (CET) program, but scoped narrowly to the accessibility and low-rise residential lift equipment that CET does not emphasize. If you're still deciding whether this is the right path for your career, our overview of What Is CAT Certification? and the broader CAT Certification resource page are good starting points before you dig into exam mechanics.

Who Administers the CAT Credential

CAT certification is owned and administered by the NAEC Certification Board, headquartered in Conyers, Georgia. NAEC sets the curriculum, maintains the exam question bank inside the Exam Builder platform, and issues the final credential once all training hours, skills verifications, and proctoring paperwork are confirmed. Because NAEC also governs the parent elevator industry certification (CET), CAT shares some administrative infrastructure with that program, but the two credentials test different equipment and different bodies of knowledge.

For readers who want the plain-language basics before the procedural detail, see What Is CAT?, CAT Meaning, or What Does CAT Stand For? - all three cover the same identity from slightly different angles for search purposes, but the underlying facts are identical to what's in this article.

The Two Qualification Pathways

NAEC built two distinct roads to CAT certification, and understanding which one applies to you is the single most important step before you spend any money on the application.

Education Pathway (Active Route)

This is the pathway available to new candidates today. It follows a two-year, five-course curriculum and culminates in a 150-question final exam requiring 75 percent correct within three hours. Candidates must also log at least 4,200 documented on-the-job training hours after candidate approval, plus complete all required skills verifications signed off by a supervisor. Application fees are $105 for employees of NAEC member companies and $160 for non-members.

Legacy Experience Pathway (Closed to New Hours)

This route was designed for technicians who already had substantial field experience when CAT launched. It required 6,000 documented on-the-job hours (three years) accrued by December 31, 2014, and used a 160-question exam drawn randomly from a question bank with no unscored trial items, requiring a scaled score of 80 to pass. It cost $735 for members or $1,180 for non-members. Because the hour-accrual deadline has passed, this pathway is effectively legacy status for technicians who already qualified under it rather than an option for someone starting fresh today.

Exam Format and Proctoring Rules

The CAT exam is computer-based, delivered through the Exam Builder platform, closed-book, and offered in English only. Unlike many certification exams that require a trip to a dedicated testing center, CAT is taken at the candidate's workplace under a two-proctor system:

• The first proctor must be an officer of the employing company.
• The second proctor must be a competent adult who is not related to the examinee, not their supervisor, and not another program examinee.

Both proctors must submit a signed and notarized proctoring statement before NAEC will issue certification. This workplace-based, dual-proctor structure is unusual and trips up candidates who assume they'll test at a Pearson VUE-style center - they won't. Build the proctor logistics into your planning early, since scheduling two available, qualified adults can take longer than studying the material itself.

The Five CAT Course Domains

The education pathway's curriculum is organized into five sequential courses, and the final exam draws its 150 questions from across all of them. Each course also functions as a content domain you should track separately while studying.

Costs, Deadlines, and Retake Rules

Money and timing matter as much as content knowledge when it comes to actually finishing CAT certification. Here's how the two pathways compare on cost:

Beyond fees, there are firm deadlines built into the process. Candidates have 90 days to complete their application once started, and 365 days from authorization to actually sit for the exam. If you fail, you must wait 30 days between attempts, and a $100 retest fee applies before your third attempt. Fail a third time, and you face a 180-day wait plus a full reapplication to the Certification Board.

Keeping the Certification Active

CAT certification is not permanent - it runs for one year and expires every December 31 regardless of when during the year you were certified. To renew, technicians must complete:

• 10 continuing education hours, including at least 1 safety hour (safety hours are capped at 3 toward the total)
• A signed Code of Ethics form
• A renewal fee of $115 for members or $210 for non-members

Technicians who complete more than the required hours in a given year can roll forward up to 4 surplus hours to the next renewal cycle, which rewards those who front-load their continuing education rather than scrambling in December.

NAEC also offers a CAT-S supervisor designation for $100 to technicians who already hold active CAT certification, which is worth considering once you've been in the field long enough to move into a lead or supervisory role.

Who Hires CAT-Certified Technicians

CAT certification is designed around a specific slice of the vertical transportation trade: accessibility equipment and private residence lifts rather than large commercial elevator banks. Employers who value the credential tend to include:

• NAEC member companies that install and service residential and light-commercial accessibility lifts
• Independent lift and stairlift dealers serving homeowners with mobility needs
• Elevator contractors expanding into private residence elevator installation, where Course 5's depth becomes directly relevant
• Service and maintenance firms responsible for inspecting inclined platform lifts and stairway chairlifts under ASME and local code requirements

Because the credential signals specific, code-referenced competency - grounded in ASME A18.1-2005, ASME A17.1-2007, NEC 2008 Section 620, and the Elevator Industry Field Employees' Safety Handbook - employers can use it as a hiring or promotion filter without re-verifying every applicant's hands-on background.

Building a Study Plan Around the Curriculum

Because the education pathway spans a two-year, five-course sequence, "studying for CAT" really means two separate efforts: absorbing course material as you go, and then doing a focused review before the 150-question final. A simple way to sequence final review is to move through the courses in the order they were taught, spending extra time on Course 5 given its size relative to the others.
