What method can help maintain students' academic privacy while posting grades?

Using a random number assigned to each student is an effective method for maintaining academic privacy when posting grades. This approach ensures that students' identities are protected, as their grades are linked to a number that only they know, rather than to their names or any other identifying information.

By implementing this method, you provide a layer of security that helps prevent any potential breaches of confidentiality. This is particularly critical in educational environments where sensitive information, such as academic performance, is involved. Such measures align with privacy laws and institutional policies that aim to protect student data.

Other options, on the other hand, either compromise privacy or do not address the need for it. For instance, posting grades with last names could lead to unintended identification, while disregarding the organization’s policy on posting grades entirely poses ethical and legal risks. Lastly, the notion that privacy is only needed for final grades neglects the importance of maintaining confidentiality throughout the academic process.
