Study plan for the CTFL
How I would prepare the CTFL v4.0 today, combining the official material with the articles on this wiki. Before starting, read the exam format: knowing how it's scored and which chapters weigh most changes how you study.
1. Download the official material
The v4.0 syllabus and the four sample exams (A–D) with justified answers, from the ISTQB website or from your local member board if you prefer studying in your language. It's all free.
2. Build the base with this wiki
The syllabus is dry if you arrive cold. These articles cover the same concepts with context and examples, preparing the ground chapter by chapter:
| Syllabus chapter | Supporting articles on this wiki |
|---|---|
| 1. Fundamentals of testing | What is QA? (includes the 7 principles), Types of testing |
| 2. Testing throughout the SDLC | The testing pyramid, Agile testing strategy, Shift-left and maturity |
| 3. Static testing | How to review a task, Acceptance criteria & DoR, Static analysis |
| 4. Test analysis and design | Test case design, Defining tests for a feature |
| 5. Managing the test activities | Bug reporting, Bug root cause analysis |
| 6. Test tools | When to automate, AI in test automation |
3. Read the syllabus, two passes
- First quick pass: understand the structure and mark what sounds least familiar.
- Second slow pass: chapter by chapter, taking notes in your own words. If a learning objective is K3, do exercises on that technique until they come out on their own.
4. Terminology: the glossary rules
K1 questions ask for exact definitions, and third-party summaries sometimes drift from the official terms. When in doubt, the source of truth is the official ISTQB glossary. This wiki's glossary works as a quick refresher, not as a substitute.
5. Sample exams, timed
- Take exams A–D under real conditions: 60 minutes, no notes.
- Review by reading the justifications, including the ones you got right: that's where the examiner's reasoning lives.
- Target before booking the exam: a stable 30+/40 (the pass mark is 26, and the real exam always feels a bit harder than your living room).
6. Booking and logistics
Pick an accredited provider (Brightest, GASQ…), choose online or in person, and if the exam isn't in your native language, request the +25 % extra time when booking. With a stable 30+/40 on the sample exams, book with confidence.
Common mistakes
- Ignoring the K3s. Eight apply-the-technique questions decide the exam; reading isn't enough — you have to do exercises on partitioning, boundary values, decision tables and state transitions.
- Studying only from summaries. Third-party summaries save time but drift from the terminology. The syllabus and the glossary are what the questions are written from.
- Memorizing without understanding. The v4.0 exam increasingly asks "why" and "in which case": the reasons behind each concept are what save you on the K2s.
Key idea
The syllabus tells you what will be asked; the sample exams show you how it's asked. Study with the former, train with the latter.
