ExploreAbout this exam
The ISTQB® Certified Tester Advanced Level Agile Technical Tester (CTAL-ATT) is an advanced-level qualification in the ISTQB® portfolio. Per the ISTQB® certification overview, it "provides a thorough introduction to the technical testing skills which are fundamental in organizations using an Agile development approach," and those skills "include testing and agile techniques, test automation approaches, and continuous deployment and delivery." That scope makes it relevant to testers, test analysts and technical testers who already work inside Agile teams and want to deepen the hands-on, engineering-side of their craft rather than test management or process leadership. It is not an entry-level certificate: ISTQB® states that the Certified Tester Foundation Level (CTFL) "is recognized as a prerequisite to all other ISTQB® certifications where Foundation Level is required," so confirm the prerequisite with your exam provider before booking. To prepare, download the official syllabus and sample exam from the ISTQB® free knowledge base, work through the syllabus chapter by chapter, and practise the techniques against a real product backlog or pipeline in your own organization. ISTQB® also lists Accredited Training Providers if you prefer a taught course. This page is independent study material and is not affiliated with or endorsed by ISTQB®.
What you'll study
About ISTQB CT-AT preparation
Do I need CTFL before taking CTAL-ATT?
ISTQB® states that the Foundation Level certificate "is recognized as a prerequisite to all other ISTQB® certifications where Foundation Level is required." CTAL-ATT is an Advanced Level certificate, so plan on holding CTFL first and verify the exact prerequisite with your local exam provider before you pay.
What does the CTAL-ATT syllabus actually cover?
The ISTQB® overview names three skill areas: testing and agile techniques, test automation approaches, and continuous deployment and delivery. Expect the syllabus to build technical tester capability around those themes rather than test management topics, which sit in separate Advanced Level certifications such as CTAL-TM.
How many questions are on the exam and how long is it?
The retrieved ISTQB® source gives no item count, duration, pass mark or fee for CTAL-ATT. Those details are set out in the official syllabus and in each exam provider's candidate information. Check your provider's page directly rather than relying on second-hand figures, which go out of date when syllabi are revised.
How hard is it compared with Foundation Level?
It is an Advanced Level certificate, so it assumes you already know Foundation Level terminology and concepts and can apply them. The emphasis is on technical practice in Agile delivery, so candidates who have never worked with automated checks or a deployment pipeline will find the material considerably harder than CTFL.
What if I fail - can I retake it?
Retake rules are an exam-administration matter and are not described in the ISTQB® source retrieved here. Exam providers and Member Boards set their own policies on waiting periods and fees. Ask your provider before booking so you understand the cost and timing of a second attempt.
How should I sequence my study?
Start with the official syllabus from the ISTQB® free knowledge base and read it end to end once for structure. Then work chapter by chapter, applying each technique to a real backlog or pipeline you have access to. Finish with the official sample exam under timed conditions, and review every wrong answer against the syllabus text.
Where do candidates most often lose marks?
Common weak spots are knowing a technique by name without being able to apply it to a scenario, and treating automation as a tool question rather than a design and maintenance question. Advanced Level questions reward reasoning about trade-offs, so practise explaining why one approach fits a given context better than another.
Is CTAL-ATT the same as CTAL-AT or CT-ATLaS?
No. ISTQB® lists them separately: CTAL-ATT is the Agile Technical Tester, CTAL-AT is the Advanced Level Agile Tester, and CT-ATLaS is Agile Test Leadership at Scale, which focuses on organizing quality and testing across multiple teams. Check the exact code on your certificate and syllabus before booking.
