State Technical Community College expects students to attend all scheduled
instructional activities. As a minimum, students in all courses must be
present for at least 75% of their scheduled class and laboratory meetings
in order to receive credit for the course. Individual departments/programs/disciplines,
with the approval of the vice president of Academic and Student Affairs,
may have requirements that are more stringent.
Attendance is required to all lab sessions unless excused by the instructor. Students missing more than four unexcused sessions will receive an "F" and no credit will be received. Students tardy past half an hour will be considered absent. |
