You have probably seen Scrum certifications on LinkedIn and wondered if they are worth anything or just a way to sell a weekend workshop. The answer sits in the middle.
In agile-heavy industries like software, a Scrum certification from a recognized body is a cheap way to show you understand the framework. It often matters more to HR filters than to the team doing the work.
What it will not do is make you a great Scrum Master. That comes from running real sprints, resolving real conflict, and shipping real software under real constraints.
So treat it as a door-opener, not a skill substitute. It is a low-cost credential that gets you past screening, and after that, your experience takes over. Buy the base level, skip the expensive tiers.
