Conduct of Course:
This course consists of approximately 3 hours of lecture per week. Some of these lectures are ration formulation applications, completed in the computer lab or practical applications completed in the Dairy Learning Center.

Attendance

Classroom and laboratory attendance is considered vital to the learning process and as significant to the students’ evaluation as examinations and reports, therefore absenteeism is recorded.

• Students having a combination of excused and/or unexcused absence of 20 percent or higher for the scheduled course hours can be required to withdraw and would then automatically receive a “RW” (required withdrawal) for the course, regardless of any other evaluation results. (RW is a failing grade).
• An excused absence is one that is verified with your instructor. Verification should be prior to the absence or the next class day following the absence. Verification of the absence may take the form of a note from your doctor/College nurse regarding illness, or a note from another instructor regarding a field trip or other activity, or authorization by your instructor following an in-person meeting. Be sure to contact your instructor and ask what they will require from you as verification for each absence. An unexcused absence is anything NOT verified by the instructor prior to the absence or the next class day following the absence.

It is the students’ responsibility to know their own absentee record.

Normal hours are 8:30 a.m. to 6:30 p.m., with potential for evening courses, exams or extended field trips. Students are expected to be available for classes during these times.
