Wordpress is part of the Web Development course that I took but not the only platform. There's Joomla, which others prefer over WP. As such, I believe the only way to get "Certified" is take the whole Web Development Course, not just WP itself. Although WP is an important part of web development, it is not web development by itself.

When we hire a web staff, we don't ask if they are "WP Certified". Experience and previous projects, that's what matters. Show me what you've done and can do.

And what does Automaticc (paid) have to do with WP (open source)?
