Who organises Node.js certification exams?

2017 Update

Currently, as of 2017, there is no Node.js certification program.

There used to be a StrongLoop Certified Node Developer program but after StrongLoop was bought by IBM the certification program was cancelled.

Right now a new certification program is under development by The Node.js Foundation in partnership with The Linux Foundation with participation of the Node.js developer community.

The progress and the road map is described here, together with a heated discussion on how it should look like that is worth reading, in the Issue #3 of the nodejs/education repository on GitHub:
