Federal student aid administration runs a governed assessment on every selected file: the ISIR, the supporting documents and the tax information checked against the verification requirements and the institution’s own policy, before any administrator judgement.
The requirement set is fixed: the federal verification items, the conflicting-information duty, and — for professional judgement under HEA §479A — an evidence standard the institution sets itself and must document against. What sits between the mandate and the decision is preparation.
