This guide is a complete working treatment of special education law for parents, advocates, educators, and counsel. Part I sets the statutory architecture and the substantive standard, tracing it from Rowley through Endrew F. and explaining what the 2017 decision changed and what it did not. Part II covers child find, evaluation, and eligibility, including the two-prong test and the traps that produce wrongful denials. Part III works the IEP itself — required contents, measurable goals, related services, and the two defects that appear in most inadequate programs. Part IV covers the least restrictive environment mandate and the order of inquiry that districts frequently invert. Part V is the procedural safeguards, which is where cases are actually won: prior written notice, the independent educational evaluation, stay put, and the due process complaint, with the burden allocation from Schaffer and the fee rules from Arlington Central. Part VI covers remedies including compensatory education and private placement reimbursement after Burlington, Carter, and Forest Grove. Parts VII through XI cover Section 504, discipline and manifestation determinations, exhaustion after Fry and Perez, dispute resolution routes in ascending order of cost, and a stage-by-stage verification list.
