Is there any reason to take "lower level" certificates?

PSM I (80 questions) covers the fundamentals of scrum.  PSM II (30 questions) requires you to not only understand the fundamentals, but also the different SM stances, as well as how to help the Developers, PO & organisation, etc. 

I would say that if you have passed PSM II then there really isn't a need to pass PSM I.  Time and money would be better spent on gaining PSM III. 

Ok, thanks. Yea, I passed PSM II with 100%. Just wanted me sure I didn't miss anything. My plan is to do lvl 2 on those that has these (like PSPO etc). Then if I find time perhaps try lvl 3. I think the time constraints could be an issue for me due medical issues. But I guess I will at least have a try one day :)

Congratulations on passing PSM II. 

I believe that the only time you would need to take the PSM I exam is if you wanted to become a PST, as that process has it down as a requirement including a specific percentage. 

Hello Daniel,

Congratulations on passing PSM II with 100%.

Can you us know if you attended the two day training from Scrum.org for the exam or was it just self study. I am planning to take the exam and would like to hear your inputs.

Thanks,

Arun.

Hi Arun

No I did not attend any class. I have been a long time advocate of agile principles. My mindset was probably already compatible and it was a matter of nailing a few semantics, the preferred size of the team etc.

So I read some books because I wanted to learn more and then I just got the idea to try the certification. 

"I think the time constraints could be an issue for me due medical issues"

You can ask Scrum.org for some adaptation of the timebox, providing medical justifications.

I was advised of that actually and have contacted them. I have an appointment with my doctor next week and will ask him to provide some documentation. I probably won't dive into PSM III yet for a while, but good to know the option exists.

Thanks Daniel for the response.

I would consider the value you will receive if you 'went back' to sit the PSM I. Assessments are there to validate knowledge. If you would like to validate your PSM I knowledge then great - go for it! If you feel that passing the PSM II validates it enough for you, then consider what it would offer you.
