What Is CAST Certification?

What Is CAST Certification?

CAST stands for Certified Alarm Security Technician, a credential issued by ETA International for technicians who install, configure, and service alarm and electronic security systems. It's a knowledge-based certification: candidates sit for a proctored written exam rather than a hands-on skills demonstration, which makes it accessible to technicians working across different regions and employers without requiring an in-person practical lab.

If you've landed here after searching "What Is CAST?" or trying to pin down the CAST meaning, note that this acronym is shared by several unrelated credentials in other industries. This article - and every other page on this site - refers exclusively to the Certified Alarm Security Technician certification from ETA International. For a plain-language breakdown of the letters themselves, see What Does CAST Stand For?

Who Issues the CAST Credential

ETA International is the certifying body behind CAST. This matters because ETA maintains the competency document that defines exactly what's tested, sets the exam delivery rules, and controls maintenance requirements. The competency document currently linked by ETA lists 13 base sections for the standard CAST exam and carries 2013/2016 copyright dates, meaning the underlying content areas have been stable for years even as specific questions are refreshed.

It's worth distinguishing base CAST from CAST(C), the Commercial add-on. This article - and the domain list below - covers the base CAST competencies only. If you're comparing the two paths, the CAST Requirements guide walks through eligibility differences in more detail.

Exam Format and Delivery

The CAST exam is a proctored written test, not a hands-on practical. You can sit for it at a physical test site through an ETA Certification Administrator using Trapeza-based testing, either on a computer or on paper, or you can test remotely through ExamRoom.AI. There's no live demonstration of wiring, soldering, or device installation - everything is assessed through written questions covering the same real-world topics a field technician handles daily.

• Question count: 75 questions
• Time limit: two hours
• Passing score: 75%
• Reference materials: none permitted; no formula sheets provided
• Calculators: allowed only under ETA's stated calculator policy

Because there are no reference sheets or open-book allowances, candidates need to have formulas, terminology, and component behavior memorized before walking in - or logging in, for remote sessions. For a deeper look at how demanding this actually is in practice, the How Hard Is the CAST Exam? guide breaks down difficulty by domain and question style.

Registration, Fees, and Retakes

The base CAST exam fee is $80. If you choose remote proctoring through ExamRoom.AI instead of an in-person test site, add $16 for the two-hour proctoring session. That's the full added cost for testing from home or the shop rather than traveling to a physical location.

ETA also gives you a safety net: one free retake is available within one year of your first exam session. The free retake covers the exam itself - if you retake remotely, the $16 remote-proctoring charge still applies separately, since that's a proctoring service fee rather than an exam fee.

The 13 CAST Exam Domains

The competency document currently splits the base CAST exam into 13 content areas. Every question on the 75-question exam maps back to one of these domains, so understanding what each one actually covers is the fastest way to know where your study time should go.

For a section-by-section deep dive into every one of these 13 areas - including what tends to trip up first-time candidates - read the CAST Exam Domains 2026: Complete Guide to All 13 Content Areas.

Stand-Alone CAST vs. Journeyman Status

One detail candidates often overlook: stand-alone CAST certification does not require CETa (ETA's core electronics certification) as a prerequisite. You can pursue base CAST on its own once you're ready for the exam content.

Journeyman status is a separate tier. It requires holding CETa plus at least two years of combined training and/or field experience. If your career goal is to eventually reach Journeyman-level recognition, plan your CETa timeline alongside your CAST prep rather than treating them as unrelated milestones. The CAST Requirements page details exactly how these prerequisites interact.

Who Hires CAST-Certified Technicians

CAST-certified technicians typically work for alarm installation and monitoring companies, security integration firms, and electrical/low-voltage contractors that handle residential and commercial alarm, camera, and access control installs. The certification signals to employers that a technician can be trusted with core tasks: running and terminating cable, wiring alarm panels and sensors, installing cameras and intercoms, interfacing subsystems, and troubleshooting faults without step-by-step supervision.

Because the domains span everything from soldering to reading schematics to basic data communications, CAST is positioned as a well-rounded field credential rather than a narrow specialty badge.

Certification Term and Maintenance

CAST certification is valid for four years from the date you pass. To keep it active, ETA requires either:

• 10 continuing-education hours annually (40 hours total over the four-year term), or
• employer/supervisor verification of relevant work activity under ETA policy

Maintenance costs $25 per year, or you can pay $100 upfront to cover the full four-year term. Letting maintenance lapse isn't just an inconvenience - it can affect your standing with employers who list CAST as a job requirement, so it's worth tracking renewal dates the same way you'd track any other license.

A Focused Way to Prepare

Generic study advice (flashcards, spaced repetition, timed drills) only helps if it's pointed at the right material. Given that CAST allows no reference sheets and tests 13 distinct domains in just two hours, a practical approach is to front-load the domains that involve memorized formulas or terminology - Mathematics and Cabling and Connectors, for example - earlier in your prep window, and save Troubleshooting and Interfacing for later once the foundational vocabulary is solid.
