How to prepare for the PSM certification? The key to preparing for the PSM certification exam is a comprehensive understanding and flexible application of the Scrum Guide, not rote memorization of definitions. The best strategy for PSM exam preparation is "deep reading of the original text + scenario-based thinking + simulation practice," focusing on understanding and application. First, you should thoroughly read the latest version of the Scrum Guide. It's recommended to read it multiple times and analyze its meaning from the perspectives of different roles (Scrum Master, Product Owner, Developer), paying particular attention to the connections between events, roles, artifacts, and their underlying principles. Second, practice frequently with official or third-party practice tests. For every incorrect answer, refer back to the Scrum Guide for support and avoid relying on experience or personal habits. In addition, it's recommended to study supplementary materials such as the Kanban Guide for Scrum Teams, the Nexus Guide (multi-team scenario), and the public assessment instructions on Scrum.org to prepare for the situational judgment and open-ended questions in PSM II/III. For advanced levels, students should also accumulate real-world examples, such as how to guide and improve teams based on Scrum principles when encountering cross-functional conflicts, changing requirements, or process bottlenecks. As the exam approaches, students can conduct several full-scale simulations to adjust their pace and ensure accurate answers under time pressure. Case Study: Effective PSM Exam Preparation for Working Professionals Adam, a former software manager with over a decade of experience managing Agile teams, successfully passed the PSM I exam. To demonstrate his deep understanding of Scrum practices, he decided to pursue the more challenging PSM II (Professional Scrum Master II) certification. He ultimately passed with a 97% score, completing his preparation in just one week. Adam set aside 1.5 to 2 hours each evening for self-study, repeatedly reviewing the latest version of the Scrum Guide and conducting role-play analysis for different roles (Scrum Master, Developer, and Product Owner). He also combined the Nexus Guide and the Kanban Guide for Scrum Teams to understand the application scenarios of multi-team collaboration and process optimization. He also used a practice test platform for frequent practice, taking screenshots of any questions he got wrong each day and referring back to the guide for the original text. To prepare for situational questions, he would construct complex real-world scenarios in his notes, such as unstable external dependencies, cross-team conflicts, and frequently changing requirements, and then simulate the best Scrum Master strategies for coping. After seven days of intensive study, Adam passed the PSM II certification on the first try with a 97% score. After receiving his certification, he began providing weekend agile coaching services to several startups, guiding teams through Sprint Retrospectives, optimizing backlog grooming processes, and promoting transparent cross-departmental communication. Through a friend's introduction, he also landed a part-time position teaching a practical Scrum course at a training center, teaching only one evening a week and half a day on weekends. Adam now earns an additional 12,000 yuan per month, which not only alleviates his family's financial burden but also provides him with valuable experience in business coaching. He plans to take on the PSM III exam in the future and gradually develop his part-time agile coaching business into a second career.
