ATTENDANCE POLICY
Regular and punctual attendance is required of all students classes for which they have registered. Students absent (excused or unexcused) for 15% of their classes or more may receive an “F” or be dropped from the course. Coming to class late or leaving early will count as ½ of an absence, coming in late or leaving early twice will count as one absence. All absences are unauthorized unless the student is absent due to illness or emergencies as determined by the instructor. It is the student responsibility to provide documentation as to the emergency for approval and judgement by the faculty member. Approved sponsored activities are the only absences for which a student may not be held liable and only when providing notification prior to the absence. Valid reasons for absence, however, do not relieve the student of the responsibility for making up required work. Students are not allowed to make up an examination missed unless approved by the instructor. A student that is compelled to be absent when a test is given, will petition the instructor, in advance, for permission to take the exams given during the course at another time. Required work not completed by due dates will not be allowed to be turned in without instructor approval. Class participation in assignments and exams will be used to determine regular attendance for online students.
Last day to Withdraw
The last day to withdraw from a course with a “W” is April 1st 2024
