How many days in advance must prior written notice be provided to parents?

The requirement for providing prior written notice to parents is generally stipulated in the regulations governing special education services. According to the Individuals with Disabilities Education Act (IDEA) and related guidelines, the specified timeframe for informing parents about changes or proceedings related to their child's Individualized Education Program (IEP) or service delivery is five days in advance. This timeline ensures that parents have adequate time to prepare for any meetings, discussions, or decisions regarding their child's educational needs. Providing this notice in advance fosters collaboration between educators and families, which is essential for effective decision-making in the special education process. Thus, the correct answer reflects the mandated five-day notice requirement.
