This is a question I get a lot, what are Scrum Alliance and Scrum.org and which is “best”? The truth is there is no best, both have different certifications and a different business model. In this post I want to explain the differences between the two and help you decide which to choose.

Let’s start with what they do. Both Scrum.org and Scrum Alliance offer training courses and certifications for Scrum Masters and Agile Professionals. Both offer a variety of courses for Product Owners, Engineers, and other professions but in this post I’ll focus purely on the scrum masters.
You can think of these organisations like Exam Boards, if you pass their exam you get a certificate which you can present to any employer and it will prove that you have a certain level of scrum knowledge. You can also show the badges off to your friends and family but personally I’d recommend against that. I spent half an hour explaining to my mum that a Scrum Master had nothing to do with Dungeons and Dragons…
Both organisations offer three levels of Scrum Master certification. For Scrum Alliance these are the Certified Scrum Master (CSM), the Advanced Certified Scrum Master (A-CSM), and Certified Scrum Professional Scrum Master (or CSP-SM). Scrum.org offers the Professional Scrum Master levels 1, 2, and 3 (more commonly known as PSM-I, PSM-II, and PSM-III).
Personally I hold the CSM from Scrum Alliance as well as the PSM-I and PSM-II from Scrum.org.
Where these organisations differ is in how they go about granting the certificates. Scrum Alliance require you to attend a training course organised by a certified trainer. The prices of these vary depending on whether they are being held remotely or in person, which country they are being held in, and the level of the course. Typically in the UK you will pay around £700 for a remote course and £2000 for an in person one. Obviously the trainer then pays a fee onto Scrum Alliance. Once you have completed the course you will be sent a link to take the exam on Scrum Alliance’s website. If you pass (the pass mark is 37/50 questions) you’ll be awarded your certificate.
Scrum.org also offer training courses. However, their courses are not a prerequisite to taking the exam. Personally I have never done a Scrum.org course, I simply logged onto the website and purchased the exam token. These vary slightly depending on level but the PSM-I exam is $150 dollars.
It is also worth noting that Scrum Alliance certificates expire and you will either need to attend another course or pay (about £30 I believe) to renew it every couple of years. Scrum.org certificates do not expire.
The next most obvious question is which is easier!? There is a general feeling that the Scrum.org exams are a little more challenging, however I’ve never seen any data to back this up. Personally I scored a couple of percent higher on the Scrum.org exam than the Scrum Alliance one however not enough to state clearly. If you’re looking for a simple answer on which one would be easier to achieve or which holds more market value then I can’t give that. I would say however that the PSM-II (and I assume the A-CSM) covers significantly more ground than the PSM-I and asks questions based drawn from personal knowledge rather than simply knowing the subject matter. There is a distinct step up in difficulty and, although I’ve never taken it I wouldn’t be surprised if the PSM-III was far more challenging again.
So there you have it, all the differences that I’m aware of between the two organisations. If you’re looking for a taught course with a certificate at the end then Scrum Alliance may be for you. If you’re interested in self study and funding then Scrum.org may be the better alternative however I’ve found that both are extremely high quality certificates.
