The ISTQB® Certified Tester – Testing with Generative AI (CT‑GenAI) is the official ISTQB® certification for AI-powered software testing. It equips professionals to apply Generative AI (GenAI), Large Language Models (LLMs), and AI testing tools across the entire software testing process. This globally recognized ISTQB® CT-GenAI certification is designed for anyone who wants to:

• Generate test cases, acceptance criteria, and synthetic test data using AI
• Use prompt engineering techniques to improve test accuracy and automation
• Identify and mitigate AI-specific risks such as hallucinations, bias, and data privacy breaches
• Integrate LLM-powered infrastructure (RAG, LLMOps, AI agents) into test environments
• Plan and execute an organizational AI testing strategy

By earning the CT‑GenAI certification, you gain international recognition as a specialist in AI in software testing. Whether you’re new to AI or experienced in testing, this certification shows employers you can apply GenAI in practical, real-world test scenarios.
