What does PSM stand for and who issues this certification?
PSM (Professional Scrum Master) is issued by Scrum.org, founded by Scrum co-creator Ken Schwaber. PSM I is the foundational level, PSM II and III are advanced. It's a rigorous knowledge-based assessment — no training required, just passing the exam.

What is the difference between PMP and PMI-ACP?
PMP is PMI's flagship general project management certification. PMI-ACP specifically validates Agile knowledge across multiple frameworks (Scrum, Kanban, SAFe, XP, Lean). Many practitioners hold both. PMI-ACP requires 21 hours of Agile training and Agile project experience.

What does SAFe certification validate?
SAFe (Scaled Agile Framework) certifications (like SAFe Scrum Master, SAFe Release Train Engineer) validate knowledge of scaling Agile across large organizations. SAFe is widely adopted in enterprises that struggle to apply team-level Agile across 50–500 person organizations.

How would you professionally introduce yourself as a certified Scrum Master in a job interview?
Professional credential introduction should include: the specific certification name and issuing body, the level, and relevant practical experience. Just naming a certification without context provides limited signal — pair it with how you've applied it.

What does 'the certification requires X hours of practical experience' mean and why does it matter?
Experience requirements mean you must document actual work hours applying the method. PMI-ACP requires 1,500+ hours of Agile project work. This distinguishes the credential from purely knowledge-based exams — it validates that you've done the work, not just read about it.
