- ETA International does not publish a salary figure for Smart Technology Systems, so any specific dollar claim should be treated with suspicion.
- The exam fee is USD 105, and the core exam is half price when taken alongside at least one endorsement.
- Certification lasts four years; maintenance costs USD 25 per year plus 10 continuing-education hours annually or an employer verification.
- The written exam runs 2 hours with a 75% passing score and requires no hands-on assessment.
What "STS Salary" Actually Means
Search for an "STS salary" and you will run into a mess of conflicting numbers, because the acronym is shared by several unrelated credentials. This guide is about one thing only: the Basic Smart Technology Systems certification governed by ETA International. If you are still orienting yourself, start with What Is STS Certification? or the shorter explainers on what STS stands for.
Smart Technology Systems is a technician-level, stand-alone credential. It validates that a person working with smart home and light commercial low-voltage systems understands safety, standards, wiring, communications, troubleshooting, and customer-facing documentation. Because the credential sits at the technician level, earnings depend on the job you hold while carrying it. The certificate is evidence of competence that supports a pay conversation, not a pay grade in itself.
Why No Reliable Salary Number Exists
There are three structural reasons a clean "average STS salary" is not available.
- No official compensation reporting. ETA publishes exam logistics, competencies, fees, and maintenance rules. It does not publish an earnings survey for Smart Technology Systems holders.
- No cohort data. Even the pass rate is not publicly disclosed, as covered in STS Pass Rate 2026: What the Data Shows. Without cohort data, nobody can credibly attribute a pay premium to the credential.
- Job titles are inconsistent. The people who sit this exam work as installers, field technicians, integrators, service techs, and low-voltage specialists. Those titles carry very different pay in different regions and company types.
Anyone quoting a precise STS salary without naming a primary source is guessing. A more useful approach is to understand the levers, then validate against real job postings and employer conversations in your area.
Where the Credential Fits in the Smart Home Workforce
The STS program is part of ETA's smart home certification family. The Basic STS is the core, stand-alone exam, and it is distinct from the separate endorsements and from the STS Master Integrator. The competency document strongly recommends, but does not require, prior ETA credentials such as CAT, DCI, DVE, FOI, FOT, FOT-OSP, or TTT. Associate CET status and ETA membership are not required either. You can read the full eligibility picture in STS Requirements 2026: Eligibility, Prerequisites & How to Qualify.
That positioning matters for earnings. A stand-alone credential with no mandatory experience hours is accessible to people entering the field, which also means it functions as a baseline signal rather than an elite differentiator. Employers who hire technicians for smart home installation, home theater and automation, security and surveillance, or light commercial low-voltage work can use it as a quick screen for foundational knowledge. For the employer-side view, see STS Jobs.
What Moves Pay for STS-Credentialed Technicians
Since there is no published figure, the most honest thing to analyze is what typically separates higher-paid technicians from lower-paid ones in this trade. The table below frames the variables qualitatively; it contains no dollar amounts on purpose.
| Pay Driver | Why It Matters | How STS Interacts With It |
|---|---|---|
| Role scope | Lead installers, integrators, and service specialists generally command more than entry-level pull-and-terminate helpers | Broad competency coverage supports movement into wider-scope roles |
| Employer type | Dealers, integrators, security firms, electrical contractors, and in-house facilities teams budget differently | A recognized credential can help in firms that market certified staff to clients |
| Region | Local labor markets and cost of living vary widely | The credential is portable, which helps if you relocate |
| Stacked credentials | Specialty endorsements and recommended ETA certifications narrow your niche | STS is the core on which endorsements are built |
| Customer-facing skill | Technicians who document and communicate well generate repeat business | Domain 11 tests exactly this skill |
| Troubleshooting speed | Faster diagnosis means more billable jobs completed | Domain 12 covers basic troubleshooting methodology |
Which Exam Domains Translate Into Billable Skills
ETA's competency document organizes the exam into twelve top-level domains and publishes no percentage weights, so no single domain can be called the heaviest. Thinking about which domains map to daily billable work is a more productive lens for earnings. A full walkthrough lives in STS Exam Domains 2026: Complete Guide to All 12 Content Areas; here is the earnings-oriented view.
Domains 3, 4, and 5: Wiring, Connectorization, and Pre-wiring
Low Voltage Wiring and Wireless Communication Technologies, Cabling - Connectorization, and Pre-wiring form the physical backbone of the job. Clean terminations and well-planned rough-in work reduce callbacks, which protects margins for employers and strengthens your value as an installer.
- Cable types, connector types, and termination quality
- Pre-wire planning before drywall closes
- Wired versus wireless technology tradeoffs
Domains 6 and 7: Electrical Basics and Communications Systems
Understanding electrical fundamentals and how communication systems carry signals is what lets a technician move beyond following instructions to diagnosing why something fails. That diagnostic ability is the skill that most separates senior from junior staff.
- Core electrical concepts a low-voltage tech must apply safely
- How residential communications systems are structured
Domains 8 and 12: Management and Basic Troubleshooting
Residential and Light Commercial Management and Basic Troubleshooting sit closest to service revenue. Techs who can resolve issues on the first visit are the ones employers want on service routes.
Domains 9 and 11: Premises Restoration and Customer Orientation and Documentation
Leaving a home or office as you found it, then documenting and explaining the work, is what drives referrals and positive reviews. In client-facing firms these soft-edge skills influence who gets promoted to lead roles.
The Cost Side of the Earnings Equation
Return on investment depends on what you pay as well as what you earn. The verified costs are modest and clearly bounded. For the full breakdown, see STS Certification Cost 2026: Complete Pricing Breakdown.
| Cost Item | Amount | Notes |
|---|---|---|
| Core STS exam fee | USD 105 | No separate member and nonmember prices are published |
| Remote proctoring (two-hour) | USD 16 additional | Local in-person proctor charges are not quoted |
| Bundled with an endorsement | Core exam at half price | Applies when taken at the same time as at least one endorsement |
| Maintenance | USD 25 per year (USD 100 over four years) | Plus 10 continuing-education hours per year, or an Employer Verification Form |
| Retake | One free eligible retake within one year | Remote-proctoring charges still apply |
ETA also advertises a USD 59.95 study resource in its STS section, but the publicly visible course catalog identifies a Security & Surveillance endorsement course rather than a distinct Basic STS course, so availability of a dedicated core course is unverified. Check ETA's current listing before you budget for it. ETA's membership page also mentions STS practice-exam access for members, though membership is not required and that access does not equate to seeing real exam questions.
The takeaway for earnings analysis: the entry cost is low enough that even a small improvement in hiring odds, scope of work, or negotiating position can plausibly justify it. For a structured look at that tradeoff, read Is the STS Certification Worth It? Complete ROI Analysis 2026.
Key Takeaway
If your employer will complete the Employer Verification Form for maintenance, you can avoid the 10 annual contact hours entirely. Ask about this before you test, since it lowers your ongoing cost of holding the credential.
Stacking Credentials to Raise Your Ceiling
Because Basic STS is the core of a larger family, the clearest path to higher earnings is specialization. ETA offers separate endorsements, and the core exam is discounted when taken with at least one of them. That bundling is a deliberate nudge toward stacking.
- Start with the core. Establish baseline competence across all twelve domains.
- Add an endorsement aligned to your employer's revenue. If your company sells security and surveillance work, that specialty is the natural pairing.
- Fold in recommended ETA credentials. Fiber, data cabling, and video-related certifications named in the competency document complement the low-voltage core.
- Pursue higher STS-family designations later. The STS Master Integrator is a separate, more advanced designation outside the scope of the Basic exam.
Specialization tends to matter more to employers than a generic badge, because it maps to a specific service line they can bill for. Plan your stack around what your local market actually buys.
How to Research Real Offers
Rather than trusting a single headline number, build your own evidence base. A disciplined approach works better than any salary aggregator.
- Collect local postings. Search for smart home technician, low-voltage installer, integration technician, and security systems technician roles in your region and note which mention ETA certifications.
- Separate role types. Install-only roles, service roles, and lead or project roles are not comparable. Sort what you find accordingly.
- Ask employers directly. Dealers and integrators will often tell you whether they pay a premium or provide exam reimbursement for certified staff.
- Request reimbursement. Many employers will cover a USD 105 exam fee, especially when it supports the Employer Verification Form pathway for maintenance.
- Document your gains. After certifying, record concrete changes such as added responsibilities, tools issued, or route assignments to support a review conversation.
For a broader sense of the roles open to credentialed technicians, see STS Jobs and the background in STS Certification.
A Domain-Ordered Plan to Get Credentialed
You cannot earn the credential's benefits without passing, and the exam is a proctored written knowledge test of 75-80 questions over 2 hours with a 75% passing score. ETA does not publicly split scored from unscored items or specify the item types. Sequencing your preparation by domain keeps the safety and standards foundation ahead of the applied topics. This is one suggested order, not an official curriculum; for more detail see the STS Study Guide 2026 and the difficulty guide.

Frequently Asked Questions
No verified average exists. ETA International does not publish compensation data for Smart Technology Systems holders, and no STS-specific earnings survey was available. Pay depends on your role, employer, region, and any stacked credentials, so compare local job postings instead of relying on a single national figure.
No. The credential is evidence of foundational competence and can strengthen a hiring or review conversation, but it does not guarantee a pay increase. Employers weigh experience, reliability, and customer skills alongside certification.
The exam fee is USD 105, with USD 16 added for two-hour remote proctoring. The core exam is half price when taken with at least one endorsement. Maintenance is USD 25 per year over a four-year term, plus 10 continuing-education contact hours annually or an Employer Verification Form.
No. Basic STS is stand-alone, and neither Associate CET status nor ETA membership is required. The competency document highly recommends prior certifications such as CAT, DCI, DVE, FOI, FOT, FOT-OSP, or TTT, but they are recommendations, not prerequisites. No degree or fixed experience hours were verified as mandatory.
ETA offers one free eligible retake within one year of your first exam session. Remote-proctoring charges remain payable if you retake remotely. Review the twelve domains, especially any areas where you felt least confident, before scheduling again.
