It is understood that class attendance is critical to students' mastery of the knowledge and skills that are taught in a specific course. Because attendance may be integral to the pedagogical process, these policies are set by faculty at the individual, departmental, or institutional level. In some cases, attendance is fundamental to course objectives.
For example, students may be required to interact with others in the class, demonstrate the ability to think and argue critically, participate in group projects, or use equipment and materials in the classroom necessary to complete the course objectives, which are not available at other times. In other instances, students can master course objectives despite some or many absences.
