Syllabus

The ISTQB® CT-AI certification exam is based on the Certified Tester AI Testing (CT-AI) syllabus.

The International Software Testing Qualifications Board (ISTQB®) provides the syllabus to its Member Boards for them to accredit training providers. The syllabus is also used to derive examination questions (including in local language where available).

Training providers will produce courseware and determine appropriate teaching methods for accreditation using the syllabus. The syllabus will help candidates in their preparation for the examination.

The full package of documents is available in Materials for download section.

Exam Structure

The specialist stream AI Testing exam consists of 40 multiple-choice questions, with a pass mark grade of 65% to be completed within 60 minutes. Participants that take the exam not in their spoken language, will receive additional 25% time, and will have 15 minutes more, or a total of 75 min.

Module Number of questions Exam length (minutes) Exam length +25% (minutes)
AI Testing 40 60 75

Accredited training providers

Exams may be taken as part of a course delivered by an Accredited Training Provider or taken independently at an examination center or in a public exam.

The typical duration of the Usability Certification Training offered by an Accredited Training Provider is 2 days. Completion of an accredited training course is not a prerequisite for participating in the exam.

Please refer to the Web Sites of the ISTQB® Member Boards and ISTQB® Accredited Training Providers for exam and training availability.
