Announcement
CT-AI v2.0 is the latest version of the ISTQB® Certified Tester AI Testing certification and replaces CT-AI v1.0.
The CT-AI v1.0 certification will be retired: the English version will remain available until April 21, 2027, and non-English versions will remain available until October 21, 2027. After these dates, all exams and training courses based on the CT-AI v1.0 syllabus will no longer be available.
Certified Tester AI Testing (CT-AI) Version 2.0
Overview
The ISTQB® Certified Tester AI Testing (CT-AI) v2.0 certification focuses on testing AI-based systems, including machine learning systems and generative AI systems such as large language models. It provides the knowledge required to design and execute tests for AI-based systems, addressing their specific characteristics, including probabilistic behavior, non-determinism, and reliance on data. It also introduces AI-specific quality characteristics relevant to testing AI-based systems.
The syllabus follows a lifecycle-based approach, including input data testing, model testing, and ML development testing, together with relevant test approaches for modern AI-based systems.
Note: The CT-AI v2.0 certification replaces CT-AI v1.0. Candidates interested in using generative AI to support testing activities should consider the ISTQB® Certified Tester Testing with Generative AI (CT-GenAI) certification, which focuses on the application of generative AI in the testing process.
