CST Certification Cost 2026: Complete Pricing Breakdown

The CST Price Tag at a Glance

The Computer Service Technician (CST) credential from ETA International is one of the more affordable entries in the IT certification world. Where many vendor exams carry triple-digit fees, the CST exam fee is a flat USD 80. That single number covers the core cost of becoming certified, and everything else in this article is about the smaller line items that can sit around it: proctoring format, retakes, preparation materials, and the cost of keeping the credential active.

Before diving in, one scope note. This article is only about the ETA International Computer Service Technician credential, the PC hardware, operating system, and troubleshooting certification. It is unrelated to surgical-technologist or civil-service exams that happen to share the same three letters, and none of their pricing applies here. If you are still confirming what the credential covers, start with our explainer on what CST certification is.

What the USD 80 Exam Fee Covers

The USD 80 fee buys you one sitting of a proctored theory examination: 80 questions in two hours, with a 75% passing score. There is no hands-on assessment, so you are not paying for lab equipment or a practical station. The exam tests knowledge across the 14 official competency headings in ETA's Computer Service Technician competency document, which you can map in detail in our complete guide to all 14 CST content areas.

Because the exam is theory-based, the format is simple and inexpensive to administer. Onsite testing is run by an ETA Certification Administrator, using either Trapeza online testing or paper-and-pencil. That means the fee is not inflated by specialized testing-center hardware. For the exact scoring threshold, see our breakdown of the CST passing score.

Remote Proctoring: The USD 16 Add-On

If you cannot reach an onsite testing location, ETA arranges remote proctoring through ExamRoom.AI. This adds a USD 16 two-hour proctoring fee on top of the USD 80 exam fee, bringing your total to USD 96 for a remote sitting. The remote option is arranged through ETA rather than booked independently, so contact them to set it up.

The decision between onsite and remote is partly a cost question and partly a logistics one:

• Onsite: No proctoring surcharge. You test through an ETA Certification Administrator on Trapeza online testing or paper and pencil. Travel to a site is your only extra cost, if any.
• Remote: USD 16 extra, but no travel. Worth it if the nearest test site is far away or your schedule is tight.

Retake Economics: One Free Attempt, Possible Extra Fee

This is where the CST pricing model is unusually candidate-friendly. ETA offers one free examination retake within one year of your initial session. If you miss the 75% threshold the first time, you do not pay another USD 80 to try again.

There is one catch worth budgeting for: the remote proctoring fee is not waived on the free retake. If you tested remotely, a retake taken remotely again carries the USD 16 two-hour proctoring fee even though the exam itself is free. Candidates who test onsite avoid this entirely.

The A+ Rollover Route

Candidates who already hold CompTIA A+ may qualify for a separate pathway. A valid CompTIA A+ (ce), meaning the continuing-education version rather than the lifetime A+, qualifies you for the CST rollover route, which also carries a USD 80 fee.

The honest takeaway on cost: the rollover fee is the same USD 80 as the standard exam, so the savings are not on the price of the exam itself. The value is in the route. If your A+ (ce) is current, you may be able to convert existing credential standing into CST without the same preparation burden as starting from zero. If you hold a lifetime A+ instead, it does not qualify, so check which version you have before assuming eligibility. Our CST requirements guide walks through eligibility and how to qualify in more depth.

Where Preparation Money Actually Goes

The exam fee is small, so preparation is where costs can vary the most. The good news is that this exam rewards structured self-study, and the official source material is free. ETA publishes the competency document that defines the 14 headings, and that document is the backbone of any sensible study plan.

Free and Low-Cost Resources

• The official competency document: Free, and it names the legacy and current technologies you are expected to know. Use it as your checklist.
• A practice test: A timed 80-question simulation is the best preparation for a two-hour theory exam. You can try ours on the CST Exam Prep practice test site.
• Hardware you already own: Disassembling and reassembling an old desktop or laptop teaches Domain 2 and Domain 11 more effectively than reading about them.

Optional Spending

• Basic electronics preparation: Standalone CST does not require CETa, but the competency document suggests CETa or equivalent basic electronics preparation. If your electronics background is thin, budget for a refresher course or book, particularly for the power concepts in Domain 9.
• Training courses: Optional, and worthwhile mainly for career-changers. See our overview of CST training options.
• A compliant calculator: A non-programmable scientific calculator is permitted and useful for power and storage calculations.

One study-planning note tied to cost: because every failed attempt either burns your free retake or adds proctoring fees, it pays to sequence your study by difficulty. Put hands-on hardware domains early while you have access to equipment, and leave Domain 14 (File Management) and the networking fundamentals in Domain 10 for later review. Our CST study guide lays out a full plan, and the CST cheat sheet is useful for final-week review.

Four-Year Ownership Cost

Many cost articles stop at the exam fee, but a certification is a four-year commitment. The CST credential lasts four years, and keeping it active has its own requirements.

Standard Maintenance

To maintain the certification you submit the maintenance form and satisfy a continuing-education requirement through one of two routes:

1. Continuing education: 10 contact hours per year, totaling 40 over the four-year cycle, or
2. Employer verification: a supervisor-completed verification confirming you are working in the field.

In both cases there is a USD 25 annual fee, which works out to USD 100 per four-year cycle. The employer-verification route is notable for working technicians: if your supervisor can attest to your work, you may avoid assembling continuing-education hours entirely and pay only the maintenance fee.

Three Realistic Budget Scenarios

To make the numbers concrete, here are three candidate profiles. Preparation spending is left qualitative since it depends on your starting point.

The Self-Studier Testing Onsite

You study from the free competency document and practice tests, test onsite, and pass on the first attempt. Your exam cost is USD 80. Over the four-year cycle, add USD 100 in maintenance fees, with the employer-verification route if available.

The Remote Tester Who Needs a Retake

You test remotely, miss the 75% mark, and use your free retake, again remotely. You pay USD 80 + USD 16 + USD 16 = USD 112. The retake itself costs nothing, but the proctoring fee returns. This is still modest, but it shows why thorough preparation matters.

The A+ (ce) Holder

You hold a valid CompTIA A+ (ce) and take the rollover route for USD 80. Confirm that your A+ is the continuing-education version and not the lifetime one, since only the former qualifies.

Weighing Cost Against Career Value

An USD 80 exam fee makes the cost side of the equation easy. The harder question is whether the credential advances your career, and that depends on where you want to work. Computer Service Technician skills map to bench technicians, field service roles, help desk support, and in-house IT support, particularly at repair shops, managed service providers, and organizations that maintain their own hardware. Browse typical roles in our overview of CST jobs.

Because the credential is inexpensive, the return-on-investment hurdle is low: even a small improvement in hiring prospects or advancement can justify a few hundred dollars over four years. For pay context without guesswork, read our CST salary guide, and for a full cost-benefit view, see whether the CST certification is worth it.

There is also a pathway consideration. The Journeyman path requires CETa plus at least two years of combined training and experience, so CST can serve as a stepping stone toward a broader ETA credential ladder. Standalone CST does not require CETa, which keeps the entry cost low if you only need the computer-service credential.
