What counts as the official standard: the PDF, the notice, or the app?

A confusion worth clearing up in plain words. The official NSPIRE standards are the ones HUD publishes — the standards documents and the Federal Register notices that adopt and revise them. Checklists, apps, courses, and this forum are tools that restate those documents; none of them outranks the source. When a tool and the HUD document disagree, the HUD document wins, every time — and the disagreement is worth reporting to whoever made the tool. That is also why this forum quotes notice numbers and dates: so you can check any claim here against the source in one step. When did a tool's wording last send your crew in the wrong direction? — Admin
