My understanding is that these certifications are being phased out. I did them about 9 months ago and even then, they were quite outdated. So I expect to see a new series of certifications available at some point, perhaps from Ontologize.
But honestly, I wouldn’t hire someone just because they had done the certification - practical ability on real projects is far more valuable. So get a dev license and build something cool - that is a far better proof of ability.
