As with all the ServiceNow 'career journey' paths, there are three levels of attainment: Associate, Practitioner and Professional.
From what I can tell, to complete the Associate level requirements, you need to complete two Now Learning courses that require payment: PPM Fundamentals and Administration Fundamentals. Each costs $US300 (for the on-demand training, live training costs more).
It looks like there are no paid course requirements for the Practitioner and Professional levels.
There are no requirements to take the components of the journeys in any particular order, so you can learn a great deal about technical project management on ServiceNow without spending any money. And if you're interested in pursuing a career as in this field, I'd highly recommend doing that.
