The ISTQB certification system follows a three-dimensional structure: by learning level (Foundation, Advanced, and Expert) and by technical stream (Core, Agile, and Specialist). The Foundation level covers general testing knowledge (CTFL v4.0). The Advanced level includes core areas such as Test Analyst, Technical Test Analyst, Test Management, as well as Agile and Expert pathways. The Specialist stream covers targeted domains including AI Testing, Generative AI Testing, Mobile Application Testing, Security Testing, and Performance Testing. The Expert level includes modules such as Test Management and Test Process Improvement. Foundation, Advanced, and Specialist certifications are valid for life, while Expert-level certifications carry a 7-year validity period. AAAdemy provides learning support closely aligned with the official ISTQB blueprint—including structured knowledge explanations, path planning, study strategies, and practice exams—helping candidates systematically build a professional testing career path and stay current with ISTQB certification updates.
