Which of the following rights do students possess?

Students possess the right to free speech and expression, which is foundational in educational environments. This right allows students to engage in discussions, express their opinions, and share their ideas without fear of censorship or retaliation, as long as such expressions do not disrupt the educational process or violate any other policies.

This fundamental right fosters a culture of open dialogue and learning, enabling students to voice their thoughts on academic and social issues, which can enhance their educational experience and contribute to their personal development. It is essential in promoting critical thinking and the exchange of diverse viewpoints, both of which are vital in an academic setting.

The other options presented do not represent rights typically granted to students. Unlimited absences can lead to negative consequences in terms of learning and academic progress, and often there are policies in place to manage attendance. The choice of instructors is usually determined by the institution rather than the individual student, given factors like class availability and faculty assignments. Finally, grading criteria are established by the institution to ensure fairness and consistency across all students, and individuals typically do not have the authority to alter these criteria.
