WordPress.org should do the certifications. Individual testing could happen at WordCamps and/or at local testing facilities like how CompTIA A+ certification is handled. Most clients do not need a programmer or a developer. They need someone who can set up a website. That means finding a host, installing WordPress, installing a theme, and installing plugins.

If someone hires a programmer to do all that, they are most likely overpaying for the work.
