About the ISTQB CT-UT Exam
The ISTQB Certified Tester Usability Testing (CT-UT) is an ISTQB Specialist certification on the Quality Characteristics track that validates skills to plan, execute and report usability evaluations of interactive systems. The syllabus covers usability and UX fundamentals (ISO 9241-11, ISO 25010), human-centered design (ISO 9241-210), dialogue principles (ISO 9241-110), inspection methods (heuristic evaluation, cognitive walkthrough), formal usability testing in lab/field/remote settings, think-aloud and RITE, usability metrics (SUS, SEQ, NPS, UEQ, completion rate, time on task), accessibility (WCAG 2.2, ARIA, screen readers), mobile usability, and defect reporting. Requires the ISTQB Foundation Level (CTFL) as a prerequisite.

ISTQB CT-UT Exam Content Outline
Usability and UX Fundamentals
ISO 9241-11 definition (effectiveness, efficiency, satisfaction); ISO 25010 usability sub-characteristics (appropriateness recognizability, learnability, operability, user error protection, UI aesthetics, accessibility); distinctions between usability, UX, and accessibility
Standards and Human-Centered Design
ISO 9241-110 seven dialogue principles (suitability for the task, self-descriptiveness, conformity with user expectations, suitability for learning, controllability, error tolerance, suitability for individualization); ISO 9241-210 human-centered design activities (context of use, user requirements, design solutions, evaluation)
User Research and Personas
Personas (research-based archetypes), user journeys and journey maps, use cases, contextual inquiry, screener questionnaires, recruitment, incentives, ethics and consent
Information Architecture
Card sorting (open, closed, hybrid), tree testing (Treejack/Optimal Workshop), navigation labels, findability signals from analytics
Inspection Methods
Nielsen's 10 usability heuristics, evaluator counts (3–5), severity scale (0–4); cognitive walkthrough four questions (learning by exploration); pluralistic walkthrough with users, developers and experts
Formal Usability Testing
Lab, field, remote moderated, remote unmoderated, A/B and multivariate testing; concurrent think-aloud, retrospective think-aloud, RITE; moderator and observer roles; Wizard of Oz; task scenarios and operational success criteria
Usability Metrics
Effectiveness (completion rate), efficiency (time on task, errors), satisfaction (SUS, SEQ, NPS, CSAT, UEQ); formative (~5) vs summative (20+) sample sizes; eye tracking (fixations, saccades, AOI, heatmaps); session recording and click heatmaps (Hotjar, FullStory, Microsoft Clarity)
Accessibility and Inclusive Design
WCAG 2.2 POUR principles, A/AA/AAA levels, contrast 4.5:1 (3:1 large text), keyboard testing, focus management, WAI-ARIA roles/states/properties, screen readers (JAWS, NVDA, VoiceOver, TalkBack), automated tools (axe, WAVE, Lighthouse), mobile touch targets (44 pt iOS / 48 dp Android), thumb zones, internationalization and RTL

Frequently Asked Questions
What is the ISTQB CT-UT exam?
The ISTQB Certified Tester Usability Testing (CT-UT) is a Specialist-level ISTQB certification on the Quality Characteristics track. It covers planning, executing and reporting usability evaluations: ISO 9241 and ISO 25010 fundamentals, the human-centered design process, heuristic evaluation and cognitive walkthrough, formal moderated/unmoderated/remote testing, A/B and multivariate testing, usability metrics, and accessibility per WCAG 2.2. The Foundation Level (CTFL) is a prerequisite.
How many questions are on the CT-UT exam and what is the passing score?
The CT-UT exam has 40 multiple-choice questions to be completed in 60 minutes (75 minutes for non-native English speakers). The passing score is 65%, equal to 26 of 40 correct answers. Higher-cognition K3/K4 application questions are weighted more, but 65% remains the threshold.
What does CT-UT cost in 2026?
ISTQB Specialist exams including CT-UT typically cost between $200 and $249 USD in the United States via ASTQB and iSQI. Pricing varies by national board and whether you book the exam alone or bundle with accredited training. Exact pricing is published on istqb.org and your national board's certification page.
Do I need CTFL before taking CT-UT?
Yes — the ISTQB Foundation Level (CTFL) is a formal prerequisite for the CT-UT Specialist exam. ASTQB and other national boards verify your CTFL credential before allowing you to register. There are no other formal experience requirements, but practical exposure to running heuristic evaluations and moderated usability tests helps significantly.
What is the difference between heuristic evaluation and cognitive walkthrough?
Heuristic evaluation is a structured inspection where 3–5 evaluators apply Nielsen's 10 heuristics to surface usability violations. Cognitive walkthrough is a different inspection where evaluators simulate a NOVICE user 'learning by exploration' and ask four questions at each step (Will the user know what to do? Will they notice the correct action? Will they associate it with the goal? Will they see progress?). Both are expert methods, but they answer different questions.
How many users do I need for a usability test?
Formative testing (find-problems) typically uses about 5 users per round per persona (Nielsen) — five users find ~85% of problems in a single iteration. Summative testing (measure usability with confidence intervals on SUS, completion rate, time on task) requires 20 or more participants per group. RITE iterates by changing the design after defects are found, often within 5 sessions.
How long should I study for CT-UT?
Plan 30-50 hours over 4-6 weeks if you are a tester new to usability research, or 20-30 hours if you have moderated tests before. The ISTQB recommends accredited training (about 21-25 instructional hours). Read the CT-UT syllabus, work through 100+ practice questions, and aim for 80%+ before booking.
