In terms of having one area to collect the subjects, I agree having a single thread to reference is a smart idea. I don't know if I personally amount to much in the way of leading the charge but certainly I think there's some unexplored area to cover such as the incredible enforcement power of NCLB (No Child Left Behind) as it pervades and affects standardized public education including special education in the IDEA and civil rights regulations such as Section 504. How recently really the IDEA and ADA/504 have come in place to protect students with disabilities and what their histories are.
I'm also interested in looking beyond at mediation, due process, case processing. Actually there is one worthy exploration in the P&A/CAP network within NDRN. That's Protection and Advocacy (P&A) System and Client Assistance Program (CAP) in National Disability Rights Network, a congressionally mandated (known) federally funded (need to verify but almost assuredly) program for legal assistance and advocacy.
Would any of that fit in to you what you were thinking? I could see some of that morphing into a Google doc later with the ability for others to edit and factcheck. Rough drafting here maybe? These things always evolve over time, with more eyes, etc.
