A collection of ColdFusion community members has co-authored a free book called Learn CF in a Week. (Disclosure: I wrote two of the chapters.)
It's completely free (pdf, epub, or just keep it online), and every chapter has an accompanying hands-on section to reinforce the concepts from the chapter with code you can follow, as well as homework if you're up for the challenge.
Every so often people ask me for training materials besides the CFWACK books... and now we have this great, free resource. If you have developers that need training from the ground up, or even just to cover some of the finer points like security or i18n, this is a great place to start.
