Really? I would understand if we were talking about military strategy or troop movements, but how is special education law and policy fairly considered to be classified information. Transparency really is a good thing! I have read news accounts that for a while one member of Congress was posting all CRS reports on his website, but it became overwhelming and he stopped providing this service.
Any way, if you have a subscription or can track it down, the title of the report is "The Individuals with Disabilities Education Act (IDEA): Supreme Court and Selected Lower Court Decisions" and I believe that the report number is R40521 (although it may be 7-5700?).
