Centre, an open source student information system that has been around for awhile, is part of the solution stack. http://www.miller-group.net/ They have a data warehouse and are proposing an open source SIF alternative and an assessment solution. While the proof is in the pudding, these guys have working demos and they look pretty good for a first run. K-12 education in dire financial straits and solutions like these could help with lower TCO. Plus, education is a collaborative industry already, which makes perfect sense for open source.
