Scrum.org provides a family of programmes for scrum learning. The idea here is to pick the course that best suits where you come from and where you intend to use these skills. The Scrum.org lays these differences out clearly on their website.

The Professional Scrum Master (PSM) and Professional Scrum Developer (PSD) courses are shown as specialisations. The Professional Scrum Foundation (PSF) Course is intended to be a course on the fundamentals and the best place to start for those new in the field.

Many questions have been asked about the distinctions between the PSM and PSD courses and whether one course is an advance version of the other. It is not a case of one course being more advanced than the other -- each course is targeted at a different audience.

The PSD course is intended for Scrum team members. In Scrum, the term Developer applies to all team members. This covers Testers (who develop test plans) and Programmers (who develop code). Therefore, if you are using Java or .Net, PSD is the recommended course.

The PSM is however targeted at Scrum Masters as well as people who want to understand why scrum works. Like the PSD and PSF courses, sufficient focus is given to 'what it is'. However, the PSM goes one step further to explain the 'why' behind it as well.

Both the PSD and PSM courses includes the course, the assessment and the certification.
