CSI Passing Score 2026: Exactly What You Need to Pass

The Number: 75% on a 50-Question Exam

The Certified Satellite Installer (CSI) credential is administered by ETA International (ETA). According to ETA's Communications Certifications page and its certification catalog, the base examination consists of 50 questions, carries a two-hour time limit, and requires a 75% passing score. There is no hands-on component. Everything you are scored on comes from the written examination.

That single figure is the answer most candidates are searching for, but the number alone leaves out the details that actually shape your preparation. This article breaks down what 75% means for a satellite installer sitting this exam, how the competency outline connects to your score, what happens if you miss it the first time, and how logistics on test day can quietly cost or protect points. If you want the broader preparation picture, the CSI Study Guide covers the full approach, and the CSI practice test site lets you rehearse against realistic questions.

What 75% Means in Practical Terms

On a 50-question exam, a 75% threshold works out to answering at least 38 questions correctly if each question carries equal weight (37.5 rounds up to 38). ETA's published materials state the percentage, not a per-question point value, so treat the 38-question figure as simple arithmetic rather than an official statement. Verify current scoring details when you register.

Practically, that gives you room for roughly a dozen misses. That sounds comfortable until you consider how the content is distributed. The official outline spans 11 headings, from satellite communications history and theory through safety. A candidate who is excellent at dish alignment and cabling but has never looked at receiver digital technology or internet transmission can burn through the margin quickly, because a handful of unfamiliar domains can each produce several misses.

A Passing Threshold Is Not a Pass Rate

It is easy to conflate "you need 75%" with "75% of people pass." They are completely different statements. The 75% figure is the cut score a candidate must reach. A pass rate would describe what share of all test-takers actually clear that bar, and ETA's public materials checked for this article do not publish one for the CSI exam. Any specific pass-rate percentage you see attributed to this credential without a cited ETA source should be treated skeptically. For a fuller discussion of what is and is not known, see CSI Pass Rate: What the Data Shows, and for a realistic sense of difficulty without invented statistics, read How Hard Is the CSI Exam?

What you can say with confidence is structural: the exam is closed to hands-on skill demonstration, it is 50 questions, and the bar is three-quarters correct. Whether that is easy or hard depends on your field background and how deliberately you prepare against the published competencies.

Where the Points Come From: The 11 Competency Headings

ETA identifies its competency requirements as the basis for examination questions. For the base CSI, those are the 11 objective headings in Section A, "BASIC - CSI, SMALL DISH CAPABILITIES." Two cautions matter here. First, the published document carries a 2013 copyright date, so it describes the outline as documented then, and some referenced products are legacy equipment compared with what you will install today. A 2026 article date does not mean the outline was revised in 2026. Second, ETA's outline lists headings without percentage weights, so there is no verified blueprint telling you how many of the 50 questions land in each area. For a heading-by-heading walkthrough, see CSI Exam Domains: Complete Guide to All 11 Content Areas.

Because weighting is not published, the safest assumption is that every heading can appear and that no single strong area will rescue a blank one. Here is what each area asks of you in practice.

Logistics That Affect Your Score on Test Day

You cannot pass without a valid sitting, so delivery mechanics deserve attention. Per ETA's Certification FAQs and its examination-site guidance, testing is proctored through an ETA Certification Administrator and can be delivered online through Trapeza or by paper and pencil, with paper examinations processed by ETA. Remote proctoring through ExamRoom.AI is available but requires registration through ETA and adds $16 for the two-hour exam. Verify current remote technical requirements when you schedule, since equipment and environment rules can change.

• Identification: Photo ID is required.
• Allowed materials: Scratch paper and nonprogrammable or scientific calculators are permitted subject to the stated rules; used scratch paper must be returned.
• Not allowed: Phones are excluded.
• Format caution: Delivery mode does not establish a particular question format or any open-book entitlement. Prepare as if you must recall everything.

Because a calculator is allowed, practice any signal-level or loss-style arithmetic ahead of time so you are not fumbling with an unfamiliar device. Scheduling specifics, including windows and deadlines, are covered in CSI Exam Dates: Testing Windows, Deadlines and Scheduling.

Retake Policy and Fee Mechanics

Missing 75% is not the end of the road. ETA offers one free examination retake within one year. Proctoring charges remain separate, so a retake is free of the exam fee but not necessarily free of administrative costs. If you test remotely, the $16 ExamRoom.AI charge also applies to an otherwise free eligible retake.

Note that endorsements are separate examinations, not additional base domains, so your 75% target applies to the base CSI exam in its own right and the 11 headings above define that scope. ETA Press was reported to list older figures of $75 for the core exam and $60 for endorsements, but that page could not be independently verified, so rely on ETA's current $80 and $65 listings. For the full financial picture, see CSI Certification Cost: Complete Pricing Breakdown.

Passing the Exam vs. Earning the Certification

Reaching 75% is necessary, but sources differ on what else the credential expects. ETA's issuer-managed Certified Satellite Installer badge specifies at least six months working in the profession, passing the examination, and compliance with the ETA Code of Conduct. The main exam listing omits that experience threshold, so attribute it to the badge criteria rather than assuming every source states the same prerequisite. Standalone CSI does not require prior CETa certification. For the full eligibility discussion, read CSI Requirements: Eligibility, Prerequisites and How to Qualify.

Also keep three things separate: the standalone CSI, the Journeyman pathway (which combines CSI with CETa or GCT1 and two years of training or experience), and the optional endorsements. A passing score on the base exam earns the base credential only.

After you pass, the certification runs on a four-year term with maintenance required. For this non-hands-on credential, ETA's published route involves a maintenance form and $25 per year ($100 per four-year cycle), with either 10 continuing-education hours annually (40 over four years) or qualifying employer verification. Do not confuse these with the separate rules for hands-on credentials.

A Score-Targeted Study Sequence

Since the 75% bar leaves limited room and the outline is unweighted, sequence your preparation so that no heading goes untouched. A sensible order front-loads the areas field installers most often under-practice.

The point of this sequence is coverage first, then speed. Run your timed mocks on the CSI Exam Prep practice tests and aim to clear 75% with margin before you sit the real exam, since a mock score that barely touches the threshold leaves no cushion for test-day nerves. A broader preparation framework is in the CSI Study Guide, and a condensed refresher is available in the CSI Cheat Sheet.
