Which statement describes the difference between federal and Illinois laws on prior written notice?

• A. Federal law requires reasonable notice; IL law requires 5-day notice.
• B. Federal law requires 10-day notice; IL law requires 10-day notice.
• C. Federal law requires notice only at IEP meetings; IL requires notice for actions.
• D. Federal law requires reasonable notice; IL law requires 10-day notice.

Answer: (D)

The key idea is how timing is handled for informing parents about actions affecting a student. Federally, prior written notice is required with a reasonable amount of time before the district makes a proposal or refuses an action. In Illinois, the rule is more specific: there is a fixed minimum of 10 days for that notice.

So, the correct distinction is that federal law uses reasonable notice, while Illinois law requires 10 days. This means Illinois imposes a concrete lead time, whereas federal standards allow the notice window to vary based on what is reasonable in the circumstances. In practice, you’d provide notice as early as possible under federal guidance, but ensure at least 10 days in Illinois.

The other statements mix up the timing or when notice must be given. There isn’t a universal 5-day requirement, federal law isn’t fixed at 10 days, and notice isn’t limited to meetings only under federal rules.
