A Certified Scrum Master is someone trained to help teams use Scrum, a method for managing projects in short cycles
The Certified Scrum Master (CSM) credential means you have taken a two-day course approved by the Scrum Alliance and passed a 50-question exam. It does not mean you manage people or make hiring decisions. Instead, you help a team follow Scrum practices — running short planning meetings, removing obstacles that slow work down, and keeping the team focused on what they committed to finishing.
The role exists because Scrum teams need someone who understands the framework deeply enough to coach others through it. That person is not a boss. They are more like a guide who makes sure the team's process stays clean and that meetings do not turn into time-wasting rituals.
Key Takeaways
- A CSM credential requires a two-day in-person or online course from a Scrum Alliance-approved trainer, followed by a 50-question exam you take when ready after.
- The exam costs money separately from the course, typically $150 to $300, and you must pass it the same day or within a set window to earn the credential.
- Your CSM stays valid for two years, then you must renew by either retaking the course or earning Scrum Education Units through other Scrum training.
- The job itself varies widely — some companies treat it as a full-time role, others combine it with development work, and some hire people with no technical background at all.
- No prior experience is required to take the course, though teams usually hire CSMs who have worked on at least one software or product project before.
What happens in the two-day course
You attend a course taught by someone the Scrum Alliance has certified as a trainer. The trainer walks through the Scrum framework — what a sprint is, what ceremonies (meetings) happen each week, what the Scrum Master's job actually is, and how to handle common problems teams run into. You also do exercises where you practice running a sprint planning meeting or handling a situation where a team member is not pulling their weight.
The course is offered both in-person and online. In-person courses often happen in cities with tech hubs, but you can also find them in smaller markets. Online courses let you join from anywhere, though they still run for a full two days (usually 9 a.m. to 5 p.m. in the trainer's time zone). The cost ranges from $400 to $800 depending on the trainer and location.
At the end of the two days, you sit for the exam. You have a limited window — usually the same day or within a few days — to take it. The exam is 50 multiple-choice questions, and you need to score 37 or higher to pass (74 percent). You take it online through a proctored system, meaning someone watches you via webcam to make sure you are not cheating.
Finding and paying for a course
The Scrum Alliance maintains a directory of approved trainers on their website. You can filter by location, date, and format (in-person or online). Each trainer sets their own price, so comparing a few options is worth the time. Some trainers offer discounts if you register early or bring a group from your company.
The exam fee is separate from the course fee and typically costs $150 to $300. You pay it when you register for the course, and it covers one attempt. If you fail, you can retake the exam, but you usually have to pay again (though some trainers include one free retake in their course price).
Some employers pay for the course and exam as part of professional development. If your company is considering Scrum, ask whether they will cover it. If you are paying out of pocket, the total investment is usually $600 to $1,100.
What the exam actually tests
The exam focuses on whether you understand Scrum practices and can recognize when a team is doing them wrong. You might see a scenario like: "A team member says they will finish a feature by Friday, but the sprint ends Wednesday. What should the Scrum Master do?" The right answer is to help the team member break the work into smaller pieces that fit the sprint, not to extend the sprint or let them commit to work outside it.
Most questions test your knowledge of Scrum terminology, the purpose of each meeting, and how to handle common team problems. You do not need to memorize the Scrum Guide word-for-word, but you should understand the core ideas. The course materials prepare you for this — trainers often give you practice exams or study guides.
The exam is not designed to be tricky. If you paid attention during the course and reviewed the materials, passing is straightforward. The Scrum Alliance publishes pass rates, and they are usually between 80 and 90 percent, meaning most people who take it pass.
What happens after you pass
Once you pass, you get a digital badge and a certificate. Your CSM credential is valid for two years from the date you pass the exam. After two years, you must renew it.
To renew, you have two main paths. The first is to retake the two-day course and exam — you pay the full fee again. The second is to earn 20 Scrum Education Units (SEUs) through other Scrum training. SEUs come from courses on advanced Scrum topics, attending Scrum conferences, or taking other Scrum Alliance-approved training. This path is cheaper if you find low-cost or free training options, but it requires more planning.
Some people let their CSM expire and retake the course later. There is no penalty for letting it lapse — you just start fresh. Others renew every two years to keep it current on their resume.
What the job actually looks like
A Scrum Master's day-to-day work depends on the company and team. In some places, it is a full-time role — you work with one team or multiple teams, run all the Scrum ceremonies, and spend time coaching people on how to work better together. In other places, you are a developer or product manager who also acts as the Scrum Master for your team, spending maybe 10 to 20 percent of your time on it.
The core responsibilities are the same everywhere: run the daily standup (a 15-minute meeting where people say what they did yesterday and what they are doing today), facilitate sprint planning (where the team decides what to work on), and remove blockers (obstacles that are slowing the team down). You also help the team reflect on how they are working and suggest improvements.
The role does not include hiring, firing, or performance reviews. You do not tell people what to work on — that is the product manager's job. You do not decide how to build something — that is the team's job. Your job is to make sure the team has time and space to do their work without interruption, and to help them get better at working together.
Whether the credential actually matters
The CSM is widely recognized in tech and product companies, especially those already using Scrum. If you are explore for a Scrum Master job, having the credential makes your resume stronger. Some companies list it as a requirement, though many will hire someone without it if they have relevant experience.
The credential is less valuable if you are not planning to work as a Scrum Master. If you are a developer or product manager who wants to understand Scrum better, the course is useful, but the certification itself will not change your job prospects. The knowledge is what matters in that case.
The CSM is also one of many Scrum certifications. The Scrum Alliance offers the CSM, but there is also the Professional Scrum Master (PSM) from Scrum.org, which has a similar two-day course and exam. Both are recognized, and employers generally do not prefer one over the other. The choice usually comes down to which trainer and schedule work for you.
Frequently Asked Questions
Do I need experience working on a software team before I take the course?
No. The course teaches you Scrum from the ground up, and you do not need prior experience to understand it. That said, if you have worked on a team before, you will recognize the problems the course talks about and get more out of the training. Many people take the course with no team experience and then land a Scrum Master job afterward.
What if I fail the exam?
You can retake it. Most trainers let you retake the exam within a certain window (often 30 days) for a fee, usually $100 to $200. Some include one free retake in the course price. Very few people fail if they paid attention during the course, so retakes are uncommon.
Can I take the course online if I am in a different country?
Yes. Online courses are available from trainers worldwide, and you can join from anywhere with an internet connection. The course will be in the trainer's time zone, so check the schedule before you register. The exam is also online and proctored, so you can take it from home.
How much does a Scrum Master job pay?
Salary varies by location, company size, and experience. In the United States, Scrum Master salaries typically range from $70,000 to $130,000 per year, with higher pay in tech hubs like San Francisco and New York. Your salary depends more on the company and your background than on whether you have the CSM credential.
Do I need to renew my CSM every two years?
Only if you want to keep the credential active. If you let it expire, you can retake the course later and get recertified. There is no penalty for letting it lapse. Many people renew because employers or clients ask for it, but it is not required to work as a Scrum Master.
