There's been some buzz about Drupal certification programs recently. Whoever takes up that task, if anyone does, I hope they implement focused certification instead of some monolithic certificate.
Server configuration, themes, module development, site architecture, and the like are all sufficiently advanced topics to merit their own certification. Breaking it down like that might also help realize certification programs sooner, if organizations could focus on developing a program just for the topics they specialize in instead of the whole of Drupal.
