This guide covers school finance from the structure of state formulas through litigation and remedy. It begins with why funding depends on local property wealth and how the federal courts left the question to the states. It then walks through the standard formula component by component, identifying where each equalizing mechanism succeeds and where it fails. Separate parts address capital finance, categorical aid, and the unequalized local margin where most disparity originates. Later parts cover state constitutional education clauses, equity and adequacy claims, costing methodologies, justiciability and remedy, the enforcement doctrines that govern relief against state officials, the federal programs layered on top with their fiscal conditions, desegregation remedies and their financial dimension, and the fiscal analysis of private school choice programs. Each part states the rule, names the recurring failure, and gives the instruction.
