- The Certified Usability Analyst exam requires at least 70% overall across 100 four-option multiple-choice questions.
- User-centered analysis and Web and application design are each about 30% of questions, so together they control most of your result.
- Standard time is 2 hours 30 minutes; the fact sheet specifies 3 hours for India and allows 4 hours for non-fluent English speakers on request.
- The published exam-only fee is USD 800 including two attempts, but regional fee, retake, and proctoring terms conflict across HFI pages.
The Number: 70% of 100 Questions
The Certified Usability Analyst (CUA) credential, issued by Human Factors International (HFI), uses a single, clearly stated pass threshold: at least 70% overall. The exam contains 100 multiple-choice questions, each with four response options, so the arithmetic is straightforward. You need to answer at least 70 of the 100 questions correctly to pass.
Two details matter immediately. First, the threshold is applied to your overall result, not to each domain separately, according to the exam specifications HFI publishes. Second, the number comes from HFI's issuer-linked CUA Exam Fact Sheet (the undated five-page edition), which is the document HFI's Exam Help Center currently links. If you are weighing whether this credential is worth pursuing at all, our ROI analysis of the CUA certification puts the passing bar in context with cost and career return.
What 70% Means in Practice
A 70% bar on a 100-question exam gives you a margin of 30 questions you can miss. That sounds generous, but the exam is built to test both factual knowledge and application. Questions are randomized from pools of equivalent items, which means two candidates can sit the same exam and see different questions covering the same competencies. You cannot memorize a fixed question set and coast.
The practical target
Because the pass line is 70%, a sensible personal target is somewhat above it. Candidates who aim exactly at 70 leave no room for the questions that are worded to trip up half-knowledge. Treat 70 as the floor, and use practice scores in the high 70s or above as your signal that you are ready. You can check yourself against realistic question styles on the CUA practice test site.
What the exam does not publish
HFI's published specifications state the threshold, the question count, and the format. They do not publish a scaled-score range, a per-question weighting scheme, or a pass-rate statistic in the documents reviewed for this article. Anything you read elsewhere that claims a specific pass percentage should be treated skeptically; we address what is and is not known in our CUA pass rate article.
How the Four Domains Feed Your Score
The exam is organized around four official competency areas, each with an approximate share of total questions. These are HFI's exam objectives, not an editorial interpretation of how much any topic matters in the real world.
| Domain | Approx. Share of Questions | Approx. Questions out of 100 |
|---|---|---|
| Domain 1: User experience foundations | 20% | about 20 |
| Domain 2: User-centered analysis | 30% | about 30 |
| Domain 3: Web and application design | 30% | about 30 |
| Domain 4: Usability testing | 20% | about 20 |
Because the percentages are approximate, expect the actual count in each area to vary slightly. The takeaway is directional: Domains 2 and 3 together account for roughly 60 of your 100 questions. A candidate who is strong in those two areas starts with a large head start toward 70 correct answers. A candidate who is weak in either one faces a steep climb, because there simply are not enough questions in Domains 1 and 4 to make up the difference.
Format, Timing, and Rules That Shape Your Score
The passing score is only one part of the picture. The exam conditions determine how efficiently you can convert knowledge into correct answers.
Time allowances
- Standard time: 2 hours 30 minutes for 100 questions, which works out to roughly 90 seconds per question.
- India: the fact sheet specifies 3 hours.
- Non-fluent English speakers: candidates can request a total of 4 hours.
What you may and may not use
This is an unusual feature of the CUA exam. HFI course materials and your personal notes are allowed. Online resources and assistance from another person are prohibited. A secure application is required to take the exam, which enforces those rules. Because notes are permitted, the exam rewards candidates who have organized reference material and know where to find an answer quickly, but it does not reward lookup as a substitute for understanding. With about 90 seconds per question, flipping through notes for every item is not viable. Our CUA cheat sheet shows the kind of condensed reference worth preparing.
Navigation and timing mechanics
- You must start within the scheduled 24-hour window.
- The exam cannot be paused once begun.
- You can skip questions, flag them, and revisit them within the current section.
- Once a section is submitted, it cannot be reopened.
Key Takeaway
Because submitted sections are locked, finish your skip-and-flag review before you submit each section. Reserve the last several minutes of every section for flagged questions rather than trusting yourself to come back later.
No prerequisites
There are no prerequisites to sit the exam, and HFI courses are optional. That means the 70% threshold applies equally to someone with years of practice and someone studying independently. See our CUA requirements guide for the full eligibility picture and CUA training options if you are deciding whether to take the courses.
Fees, Attempts, and Retake Windows
Your passing strategy should account for the money and the number of attempts you have. The published figures follow the currently linked five-page fact sheet:
| Item | Published Terms |
|---|---|
| Exam-only fee | USD 800, including two attempts |
| Separate exam purchase after completing all four CUA courses | USD 400, including two attempts (per the five-page fact sheet) |
| Training packages | Exam included |
| Included retake window | Six months |
| Certification expiry | Does not expire |
Two attempts bundled into the fee changes the risk calculation. A first attempt that falls short of 70% does not force you to pay the full fee again within the included window, which is a reason to treat a first sitting as a serious attempt rather than a casual trial. But a retake is still a second sitting of a randomized exam, not a repeat of the same questions, so you should use your score experience to repair weak domains rather than simply resit. For a fuller money picture, read our CUA certification cost breakdown.
Conflicting Published Terms to Resolve Before Booking
HFI's own pages do not agree with each other on several points, and a careful candidate should know where. The specifications in this article follow the currently linked five-page CUA Exam Fact Sheet, but regional booking terms must resolve the differences below.
- Fee for course graduates: the legacy two-page fact sheet quotes USD 230 for course graduates, while the current five-page sheet lists USD 400 including two attempts for a separate exam purchase after all four courses.
- How the USD 400 is described: the current FAQ calls the USD 400 charge an exam reattempt, while the linked five-page sheet describes it as a separate exam purchase with two attempts.
- Proctoring in India: the current FAQ retains classroom-proctoring wording, and the legacy sheet also says classroom proctoring, but the linked five-page sheet specifies online proctoring.
- Retake window: HFI's India exam page gives a one-year free-retake window, whereas the five-page sheet, the current North America course FAQ, and the general exam page give six months.
- Naming: HFI's current marketing page uses "Certified Usability Architect" and revised course names, while the linked exam documents and FAQ retain "Analyst." This article preserves the reviewed Analyst scope and does not substitute any Architect curriculum.
What to Master in Each Domain
Knowing the pass line is useful only if you know where the points come from. The detailed topic list sits in HFI's one-page outline of topics covered in the test. The blocks below translate the four official domains into study priorities. For the full breakdown, see the domains guide.
Domain 2: User-centered analysis (about 30%)
This is one of the two largest areas. Questions test whether you can understand users and their work before design decisions are made, and apply that understanding to realistic scenarios.
- Be ready for scenario questions that ask which analysis activity fits a given situation, not just definitions.
- Know how analysis outputs feed later design decisions.
- Practice distinguishing between what users say, what they do, and what the evidence supports.
Domain 3: Web and application design (about 30%)
The other 30% domain. It covers the design of web sites and applications from a usability perspective, and it rewards applied judgment about interface and interaction choices.
- Expect application-style questions that present a design problem and ask for the best response.
- Be fluent in the terminology the HFI outline uses so you can recognize it quickly under time pressure.
- Build a condensed reference of design principles you can scan in seconds, since notes are allowed.
Domain 1: User experience foundations (about 20%)
The conceptual base. These questions are often more factual, which makes them valuable, reliable points if you have learned the vocabulary and core principles.
- Treat this domain as your most dependable source of correct answers.
- Master the foundational definitions so you are not spending time reasoning through basics.
Domain 4: Usability testing (about 20%)
Covers how usability is evaluated and how findings are applied. Expect questions on method selection and interpretation.
- Know when each evaluation approach is appropriate and what it can and cannot tell you.
- Be able to interpret scenario descriptions of a test and identify the correct next step or conclusion.
If you are calibrating how demanding these areas are, our difficulty guide for the CUA exam discusses what makes the application-style questions harder than pure recall.
A Domain-Weighted Preparation Plan
Rather than a generic schedule, sequence your preparation by how many questions each domain controls and how much each one builds on the others. This single plan is deliberately tied to the four CUA domains.
Domain 1 foundations
- Learn the core vocabulary and principles; these are quick, reliable points and they underpin the larger domains.
- Download the HFI outline and mark every topic you cannot explain.
Domain 2: User-centered analysis
- Spend the most time here; it carries about 30% of questions.
- Work through scenarios and explain your answer choices aloud.
Domain 3: Web and application design
- The second 30% domain; build your condensed design reference sheet for use during the exam.
- Focus on choosing the best response among plausible options.
Domain 4 plus full-length practice
- Cover usability testing methods, then take timed 100-question practice runs.
- Repair your lowest-scoring domain first, weighting by its share of questions.
For a broader approach to structuring your preparation, our CUA study guide expands on materials and sequencing, and you can drill under timed conditions with the practice exams.
After You Pass: Credential and Career Value
Clearing the 70% bar earns a credential that does not expire, which distinguishes it from certifications that require renewal. That permanence is part of the value case. Employers in user experience, usability, and interaction design roles recognize HFI as a long-established training and certification provider in the human factors field, and the credential is most useful for candidates positioning themselves for analyst and UX practitioner work. To see how it translates into roles and pay, explore CUA jobs and the CUA salary guide, which treat earnings qualitatively rather than quoting unverified figures.
FAQ
You need at least 70% overall. With 100 multiple-choice questions, that means answering at least 70 correctly.
The published specification states the 70% requirement as an overall threshold. Still, Domains 2 and 3 are each about 30% of questions, so weakness in either makes the overall target much harder to reach.
Standard time is 2 hours 30 minutes, with 3 hours specified for India and up to 4 hours available on request for candidates not fluent in English. The exam cannot be paused, and you must start within the scheduled 24-hour window.
Yes. HFI course materials and your personal notes are allowed. Online resources and assistance from another person are prohibited, and a secure application is required.
The published exam-only fee of USD 800 includes two attempts, and the five-page fact sheet gives a six-month included retake window. Because HFI pages disagree on some regional retake and fee terms, confirm your exact terms before booking.
No. According to the published specifications, the certification does not expire. For scheduling details, see our CUA exam dates guide.
