As a result of FERPA considered best practice, what action is prohibited?

Posting test scores on a board is prohibited under FERPA because the law is designed to protect the privacy of student education records and personally identifiable information. When test scores are made public in a manner that identifies individual students, it violates the confidentiality that FERPA seeks to uphold. This includes displaying scores in a way that others can see which student achieved which score, thus compromising their privacy.

In contrast, sharing student demographics and mailing grades to parents can typically be done within the guidelines provided there is proper authorization. Student performance reports may also be shared in secure ways that protect individual identities. The core principle of FERPA is to ensure that students' educational information remains private and secure, particularly against unauthorized public disclosure that could lead to identity breaches or unwarranted exposure of personal academic data.
