The Scrum certification system spans multiple internationally recognized platforms, aiming to validate professional agile capabilities. Scrum Alliance offers a well-known pathway, including entry-level Certified ScrumMaster® (CSM) and Certified Scrum Product Owner® (CSPO), advanced certifications such as Advanced Certified ScrumMaster (A-CSM) and Advanced Certified Scrum Product Owner (A-CSPO), and top-level credentials like Certified Scrum Professional – ScrumMaster (CSP-SM) and Certified Scrum Professional – Product Owner (CSP-PO). Scrum.org provides rigorously assessed certifications based on professional Scrum competencies, including Professional Scrum Master Levels I/II/III (PSM I/II/III) and Professional Scrum Product Owner Levels I/II/III (PSPO I/II/III), along with specialized certifications covering development, scaling, Kanban, backlog management, and user experience. All certifications require online application. Maintenance mechanisms vary: Scrum Alliance certifications must be renewed every two years through SEUs, while Scrum.org certifications do not require renewal and are maintained through assessments. AAAdemy provides learning support closely aligned with official certification blueprints—including structured knowledge explanations, path planning, study strategies, and online practice exams—helping candidates efficiently plan their professional paths and stay current with certification updates.
