Course Overview

The ISTQB® Certified Tester AI Testing (CT-AI) v2.0 is a specialized certification designed for professionals involved in testing AI-based systems, including testers, test analysts, test engineers, data scientists, and software developers. It prepares candidates for the ISTQB® Certified Tester AI Testing (CT-AI) v2.0 certification exam, which validates expertise in assessing machine learning models, neural networks, and generative AI systems. With AI adoption accelerating—73% of enterprises now deploying AI solutions according to Gartner—this certification addresses the growing need for skilled professionals who can ensure the reliability, fairness, and performance of AI systems across industries such as healthcare, finance, and autonomous technologies.

This course emphasizes hands-on learning through practical exercises using industry-standard tools and platforms, including Python, Jupyter Notebooks, scikit-learn, TensorFlow, and Google Colab. Students engage in real-world labs focused on data preparation, bias detection, model evaluation, and adversarial testing, simulating environments used by leading AI development teams. A key project involves conducting metamorphic testing on a machine learning model where traditional test oracles are insufficient, allowing learners to validate outputs under transformed inputs—a critical skill for testing non-deterministic AI behaviors within a cloud-based lab environment.

The ISTQB® Certified Tester AI Testing (CT-AI) v2.0 certification is internationally recognized and aligns with ISO/IEC 25059 standards for AI quality characteristics, making it a valuable credential for advancing in AI-focused quality assurance roles. Certified professionals can expect competitive salaries, with AI testers in the U.S. earning between $90,000 and $170,000+ annually, reflecting a significant premium over traditional QA roles. Koenig Solutions supports learners with official courseware, 1-on-1 mentoring, and a Guaranteed-to-Run schedule, ensuring flexible access to training. Earning this certification positions professionals to lead AI testing initiatives, contribute to robust ML system validation, and drive quality in next-generation intelligent systems.
