Wrightslaw.com is a good place to start regarding special education law generally. It will also give you information in the mechanics of filing for due process and conducting a hearing. If you already have a good working knowledge of the ed code and IDEA, you are in good shape. Due process is an administrative proceeding, not a civil proceeding, so the rules of evidence, objections, etc. are more relaxed than in a civil litigation. Also, the process is designed, theoretically, for non-atttorneys, so don't feel that you are going to be expected to know what an attorney would know regarding the logistics of putting on a case. Good luck, and let me know if I can be of further assistance.
