ISTQB CTFL
ISTQB Certified Tester Foundation Level (CTFL)
The ISTQB Certified Tester Foundation Level (CTFL) is the world's most widely held software testing certification, with over 1 million certificates issued. The 2023 version covers testing fundamentals, testing throughout the software development lifecycle, static testing techniques, test analysis and design (black-box and white-box), test management, and tool support for testing. CTFL is the essential entry-level credential for QA engineers and software testers globally.

Sample ISTQB CTFL Practice Questions
Q1.During acceptance testing, the customer discovers that some implemented features do not align with their expectations, despite passing system tests. What is the best course of action?
- Review and update acceptance criteria to reflect customer expectations and re-test accordingly.Correct
- Report defects and defer resolution to post-release maintenance.
- Ignore the discrepancies since system tests passed successfully.
- Blame the development team for not implementing requirements correctly.
Acceptance criteria should accurately reflect customer expectations; reviewing and updating them ensures alignment and proper verification. Deferring resolution ignores customer needs before release. Ignoring discrepancies risks customer dissatisfaction. Blaming is unproductive and does not resolve the issue.
Q2.A tester is employing error guessing to design test cases for a newly integrated payment system. What is the best practice to improve the effectiveness of this technique?
- Leverage previous experience and documented defects to anticipate likely failure pointsCorrect
- Randomly select inputs to explore unexpected errors
- Use only the requirements specification as a basis for test case design
- Focus exclusively on boundary value analysis to find errors
Error guessing is most effective when based on experience and historical defects to predict error-prone areas. Random input selection lacks targeted insight. Using only requirements ignores experiential knowledge. Boundary value analysis is a different technique and does not encompass error guessing.
Q3.Which scheduling technique allows dynamic adjustment of test activities based on progress and emerging risks during test execution?
- Rolling wave planning, which plans near-term activities in detail and future activities at a higher levelCorrect
- Fixed scheduling with no changes allowed once the plan is set
- Waterfall scheduling with sequential phase completion before next phase starts
- Random scheduling to adapt flexibly to daily changes
Rolling wave planning supports detailed short-term and high-level long-term planning, enabling adjustments based on progress and risks. Fixed scheduling is rigid and inflexible. Waterfall is sequential and less adaptive. Random scheduling lacks structure and predictability.
ISTQB CTFL Frequently Asked Questions
What does ISTQB CTFL stand for?
ISTQB CTFL stands for ISTQB Certified Tester Foundation Level (CTFL). It is administered by ISTQB.
Who administers the ISTQB CTFL?
The ISTQB Certified Tester Foundation Level (CTFL) (ISTQB CTFL) is administered by ISTQB. For official information, visit the ISTQB website.
How many questions is the ISTQB CTFL?
The ISTQB CTFL consists of 40 questions. Candidates are given 60 minutes to complete the exam.
What is the passing score for the ISTQB CTFL?
The passing score for the ISTQB CTFL is 65% (26/40), as set by ISTQB. Scoring methodology and passing standards may be updated periodically. Always verify current requirements with the governing body.
How much does the ISTQB CTFL exam cost?
The ISTQB CTFL exam fee is $250 USD (varies by provider). This fee is set by ISTQB and may vary by testing centre, region, or membership status. Additional fees for registration or rescheduling may apply.
What is the difference between ISTQB CTFL 2018 and 2023?
ISTQB CTFL 2023 is a major revision. It slimmed from 6 to 5 chapters, removed some agile content (now covered separately in the Agile Tester extension), expanded coverage of test analysis techniques, and updated coverage of testing in Agile/DevOps. The 2023 version has 40 questions (down from 40 in 2018 as well) but with updated content. Most exam providers have transitioned to the 2023 syllabus.
What is equivalence partitioning and why is it on the exam?
Equivalence partitioning divides input data into groups (partitions) that should all be handled the same way by the system, then tests one value from each partition. For example, if a field accepts ages 1–120, the partitions are invalid (<1), valid (1–120), and invalid (>120). Testing one value from each partition covers all without testing every possible input. It is a fundamental black-box test technique heavily tested on CTFL.
What certifications come after CTFL?
ISTQB has Advanced Level certifications: Test Manager (CTAL-TM), Test Analyst (CTAL-TA), and Technical Test Analyst (CTAL-TTA). There are also specialist certifications including AI Testing, Agile Technical Tester, Model-Based Tester, and Security Tester. All require CTFL as a prerequisite.
Is ISTQB CTFL worth it in an Agile/DevOps environment?
Yes, CTFL covers both traditional and Agile testing contexts. The 2023 revision explicitly acknowledges DevOps and CI/CD pipelines in the testing lifecycle. Many large organizations (banking, insurance, government, telecom) require CTFL for QA roles. The certification validates systematic testing knowledge that improves quality regardless of methodology.
