ISTQB Specialist (CT-GenAI v1.1) Mock Exam #1
A full-length practice exam for the ISTQB Certified Tester Testing with Generative AI (CT-GenAI) v1.1 syllabus, in force since April 2026. It follows the official exam format exactly: 40 questions worth 46 points in total, 60 minutes, and 30 points needed to pass (65%). Scoring is weighted the way the real exam weights it — a K1 or K2 question is worth 1 point and a K3 question 2 points — so the six K3 items carry 12 of the 46 points between them. The questions reproduce the official distribution across the five chapters: 7 from Introduction to Generative AI, 11 from Prompt Engineering (16 points, and the home of five of the six K3 questions), 10 from Managing (AI) Risks, 5 from LLM-Powered Infrastructure and 7 from Deployment & Integration. The K-level mix matches the published structure as well: 8 questions at K1, 26 at K2 and 6 at K3. The applied questions are the ones that decide the result, and in this mock they are real tasks rather than definitions: rewriting a prompt so that test conditions cover every rule and boundary of an insurance quote requirement, spotting that boundary values returned for a two-decimal money field are wrong, specifying a synthetic test data set that satisfies its own consistency rules without seeding the prompt from production, improving a user story review so each issue can be checked against the text, and choosing controls for a pilot after a data disclosure, an unreviewed reuse and a silently omitted business rule. Every answer option — correct and incorrect alike — carries its own rationale, and every question has an overall explanation, so a wrong answer tells you which misconception to fix rather than only that you lost a point. Remember that CT-GenAI is about testing with generative AI; testing AI-based systems is the subject of CT-AI, which is a different exam.

What this mock covers
This paper draws 40 questions from 5 chapters of the ISTQB CT-GenAI v1.1 syllabus. The split below is read from the questions bound to this mock, so it is the paper you will actually sit rather than a target.
| Chapter | Questions | Share | Points |
|---|---|---|---|
| Chapter 1 · Introduction to GenAI for Software Testing | 7 | 18% | 7 |
| Chapter 2 · Prompt Engineering for Effective Software Testing | 11 | 28% | 16 |
| Chapter 3 · Managing Risks of GenAI in Software Testing | 10 | 25% | 11 |
| Chapter 4 · LLM-Powered Solutions for Software Testing | 5 | 13% | 5 |
| Chapter 5 · Deploying and Integrating GenAI in Test Organizations | 7 | 18% | 7 |
Scoring is weighted: 40 questions are worth 46 points, because a question at a higher cognitive level counts for more. Revise the heavier chapters first.
Cognitive levels in this mock
Each of the 40 questions is mapped to a syllabus cognitive level - K1 recall, K2 comprehension, K3 application, K4 analysis. A paper heavy on K3 asks you to apply a technique, not to name it.
- K1 - Remember8 (20%)
- K2 - Understand26 (65%)
- K3 - Apply6 (15%)
Practise one chapter at a time
If this mock exposes a weak chapter, drill that chapter on its own before sitting another full paper.
