To help train fellow creative dept. personal, i've used the "Classroom in a Book" series by Adobe.
 
The books contain self-paced lessons designed to fit within busy schedules.

They also have a CD with customized files to guide the readers through lessons and special projects.

I like that they have sample test questions from Adobe's certification exam (if you're interested in pursuing it further)...

Adobe publishes them through "Peachpit" so you know the caliber is up there. you can find them on amazon (possibly even find a good used one for cheap)
