The FAPE standard after Endrew F.
In 2017 a unanimous Supreme Court held that to meet its substantive obligation under IDEA, "a school must offer an IEP reasonably calculated to enable a child to make progress appropriate in light of the child's circumstances." That displaced the Tenth Circuit's rule that an IEP sufficed if it conferred benefit "merely more than de minimis" — a test the Court called markedly less demanding. Where grade-level advancement is not a reasonable prospect, the program must still be "appropriately ambitious in light of his circumstances," because "every child should have the chance to meet challenging objectives." The Court was explicit that this describes a general standard, not a formula.[1]
