Which act regulates the confidentiality of test records in educational settings?

The Family Educational Rights and Privacy Act (FERPA) is the correct answer because it is the federal law that specifically regulates the privacy of student education records, including test records. FERPA grants parents and eligible students certain rights regarding access to education records, the right to request amendments to those records, and the right to consent to disclosures of personally identifiable information contained within education records.

This act plays a crucial role in ensuring that students' academic performance and personal information are kept confidential, which is vital for fostering a trustworthy educational environment. Institutions must adhere to FERPA guidelines to protect students' rights, which emphasizes the importance of confidentiality in educational settings.

The other options do not have the same established federal authority or specific focus on the privacy of educational records that FERPA does. While other acts may address related issues, they do not hold the same legal framework or scope concerning the confidentiality of student test records.
