ISTQB CTFL Exam Format Explained: Questions, Time, Pass Mark

The ISTQB Certified Tester Foundation Level (CTFL v4.0) exam is a 60-minute, closed-book test of 40 multiple-choice questions. You pass by scoring at least 65% — 26 of the 40 available points. Every question is worth one point, there is no negative marking for a wrong answer, and the questions are drawn from the six chapters of the official v4.0 syllabus.

How many questions are on the ISTQB Foundation exam?

There are exactly 40 multiple-choice questions, each worth one point, for a maximum of 40 points. There are no essay, coding or practical tasks — the whole exam is selectable answers.

• Most questions have a single best answer — you choose one option.

• A small number explicitly state that more than one answer is correct (for example, "select TWO"); you earn the point only if every required part is correct.

• It is closed-book: no notes, books or devices. A simple, non-programmable calculator is permitted and must be supplied by the candidate.

How long is the exam, and do non-native speakers get extra time?

The standard time limit is 60 minutes. If you sit the exam in a language that is not your native language, you receive an extra 25% — 75 minutes. That works out to roughly 90 seconds per question, which is comfortable for recall questions but tighter for the apply-level ones that need a short calculation.

What is the CTFL pass mark?

The pass mark is 65%, which is 26 correct out of 40. There is no negative marking, so an unanswered question and a wrong answer cost you the same — always answer every question, even if you have to guess. Computer-based exams typically show a provisional pass/fail result on screen as soon as you finish.

Which cognitive (K) levels does the exam test?

CTFL v4.0 tests three cognitive levels, and every learning objective in the syllabus is tagged with the level expected of you:

• K1 (remember) — recall a term or fact, such as a definition from the ISTQB glossary.

• K2 (understand) — explain, compare or classify concepts; this is where most questions sit.

• K3 (apply) — actually apply a technique, for example deriving boundary values or completing a decision table. These take the most time and are where a calculator and scratch work help.

How are the 40 questions distributed across the syllabus?

The 40 questions are spread across the six syllabus chapters in proportion to the number of learning objectives each chapter has. Test analysis and design (Chapter 4) carries the most questions, followed by managing the test activities and the fundamentals of testing, while static testing and test tools carry the fewest. For the exact per-chapter point breakdown and a weighting diagram, see our complete CTFL v4.0 guide. The practical takeaway: give the heavily weighted chapters proportionally more study time.

What happens on exam day?

The exam is delivered by an ISTQB member board or an accredited exam provider, either at a test centre or as a remotely proctored online session. You confirm your identity, the proctor checks your environment, and the timer starts. You may flag questions and revisit them before submitting. Because the test is closed-book, the only aids allowed are a simple non-programmable calculator and any scratch material the provider permits. The mandatory rules and the question style come straight from the official ISTQB CTFL syllabus and sample exams.

Can you retake the exam if you fail?

Yes. There is no cap on attempts, but you pay the exam fee each time and may need to wait a short period set by your provider. Because there is no negative marking and 65% is an achievable bar, candidates who consistently score 75% or higher on full-length, timed mock exams tend to pass on the first attempt.
