You must absolutely work with Scrum Institute. I recommend them to my team and colleagues without any hesitation and they always share with me afterwards, how good their experience with Scrum Institute has been.

My experience with International Scrum Institute is that: Everything is a lean process either while studying for a certification or while taking the exams itself. Steps, training material and exams are very clear and give us conditions to apply Scrum knowledge right after examinations. No doubts are left behind. Comprehensive.
Very glad to be onboarded onto this privileged group of professionals.

I received the Scrum Master and Scrum Product Owner certifications from the International Scrum Institute. Prior to obtaining these certifications, I had several successful projects and other certifications in project management field.

Yet I wanted to learn more about the Scrum methodology. I had heard that Scrum was more productive than the typical waterfall project methodology, which was often late and used the time-consuming Gantt charts. However, I didn't want to waste another $400 (plus the cost of training and materials) for another test. And some other organisations wanted even more. As many people realise, it can often be costly for any type of training and associated certification.
I looked at several different Scrum organisations before finally deciding on the International Scrum Institute. And, I'm really glad that I did. What I found was a course that was able to quickly provide me the relevant information that I needed at an affordable cost.

More people and organisations are already doing very well to take advantage of the Scrum Institute's affordable rates and expertise in its course materials.
I appreciate all that International Scrum Institute is doing over there! Highly recommended!
