Jim Shore and Andrew Black are teaching an Extreme Programming course this summer at Portland State University. The course includes credit for undergraduate or graduate programs.
Jim writes about it in the xpportland yahoo group...
This is an in-depth course covering all aspects of XP, with emphasis on the planning game, continuous integration, test-driven development, large-scale design, testing, and retrospectives.
This course is a steal at $783.50 for Oregon residents. It's an eleven-day course that takes place over four weeks.
