What must be provided to parents once per year according to procedural safeguards?

The requirement to provide parents with a parent's rights booklet once per year is a critical aspect of procedural safeguards in the context of special education. This booklet outlines the rights of parents and guardians regarding their child's education, including information on their rights to participate in decision-making processes, access educational records, and seek assistance concerning evaluations and Individualized Education Programs (IEPs).

This information is essential as it empowers parents, informing them about the legal protections and services available to their children with disabilities. Ensuring that parents receive this booklet annually helps to reinforce their understanding of their rights and the educational processes that affect their child. This directly supports the principle of parent involvement in the educational system, which is a key component of effective educational planning and advocacy for students with special needs.

The other options, while relevant to school-related communications, do not specifically fulfill the legal obligation established by procedural safeguards in special education law.
