ExploreAbout this exam
The ISTQB Certified Tester Foundation Level (CTFL) is the entry-level credential in the ISTQB Certified Tester scheme. Its purpose is to establish a shared vocabulary and a practical grounding in software testing concepts that hold across delivery approaches - the syllabus is described as relevant to Waterfall, Agile, DevOps and Continuous Delivery. The target audience is broad: testers, test analysts, test engineers, test consultants, test managers, user acceptance testers and software developers, plus adjacent roles such as project managers, quality managers, business analysts and IT directors who need a basic understanding of testing. The published content spans six areas: fundamentals of testing; testing throughout the software development lifecycle; static testing; test techniques; test management; and tool support for testing. Officially, the exam is 40 multiple-choice questions worth 40 points, lasts 60 minutes with 25% extra time for non-native language candidates, and requires 26 points to pass. Note that these figures are published for CTFL v3.1, which the ISTQB site now marks as retired, while CTFL 4.0 is labelled the current Foundation Level certification. Preparation options are accredited training (classroom, virtual or e-learning) or self-study using the syllabus and recommended reading. The credential is also the stated prerequisite for other ISTQB certifications that require Foundation Level.
What you'll study
About ISTQB Foundation preparation
What is the exam format and pass mark?
For CTFL v3.1 the published structure is 40 questions, 40 total points, 60 minutes of exam time and a passing score of 26. Questions are multiple choice. Extra time of 25% is allowed for candidates sitting the exam in a non-native language.
The site says v3.1 is retired - which version should I study?
The page for the Foundation Level exam structure is labelled 'CTFL v3.1 [Retired]', while the certifications overview lists 'CTFL 4.0' as the current Foundation Level certification without publishing its exam structure. Before booking, confirm with your exam provider which syllabus version your exam follows.
How much time do I get per question?
Sixty minutes for 40 questions is roughly 90 seconds each, and some items are scenario-based and take longer than recall questions. Non-native language candidates get 25% additional time. Practise with timed sets so you know your personal pace before exam day.
Is the exam hard? What trips candidates up?
Coverage is broad rather than deep: six chapters from fundamentals through tool support. Common failure modes are memorising definitions without being able to apply techniques such as equivalence partitioning or boundary values, skipping static testing and reviews because they feel less technical, and ignoring test management topics like risk and defect management.
Can I retake the exam if I fail?
The source material does not state a retake policy. Retake rules, waiting periods and fees are set by the exam provider and the relevant ISTQB Member Board in your country, so check directly with the provider you book through before assuming a re-sit window.
Do I have to take an accredited training course?
No. ISTQB highly recommends accredited training because it ensures materials have been assessed for relevance and consistency against the syllabus, but the site explicitly says self-study using the syllabus and recommended reading material is also an option for preparing for the Foundation Level exam.
In what order should I study the syllabus?
Follow the published content order: fundamentals of testing; testing throughout the software development lifecycle; static testing; test techniques; test management; tool support for testing. The early chapters supply terminology the later ones assume, and test techniques reward the most practice, so budget extra time for designing tests by hand.
What can I take after passing?
Holders become eligible for the next stage of the Core stream - Test Analyst, Technical Test Analyst or Test Management at Advanced Level - or can follow the Agile or Specialist streams to build specific skills. The Foundation Level certificate is also a stated prerequisite for other ISTQB certifications that require it.
Does the certificate expire?
The source does not state a validity period for the Foundation Level certificate, so no expiry can be quoted here. Validity rules, where they exist, are administered by ISTQB Member Boards; confirm with your local board or the Successful Candidate Register before relying on an assumption.
