Grading ScaleThe grading scale is detailed in the Catalog and Student Handbookand listed below for reference. All faculty membersfollow this scale when assigning grades to reflect a given student's performance in the classroom.

Grade Numerical Equivalent Grade PointA/A* 90-100 4B/B* 80-89 3C/C* 70-79 2D/D* 60-69 1F/F* 0-59 0

Effective Summer Quarter 2006, Athens Technical College replaced the S/U grading system used for learning supportclasses with an A*-F* grading system. The registrar uses an asterisk (A*, B*, C*, D*, F*, W*, WF*, WP*) to designate

learning support course grades on transcripts and grade reports because these grades are not components of the termgrade point average.

Academic Support Center:

The Academic Support Centers of Athens Technical College (ATC) provide free tutoring for enrolled students. Bothinstructors and peer tutors provide tutoring in almost all subjects offered by the college. Information about the Centeris accessible via the ATC website athttp://www.athenstech.edu/StudentDevelopmentServices/AcademicSupportCenter.To find out the specific services available on the Athens, Greene, and Walton Campuses, please call (706) 583-2839. Tocontact the Academic Support Center on the Elbert County Campus, please call (706) 213-2129.

Attendance

Regular class attendance is important and expected. The college considers both tardiness and early departure fromclass as forms of absenteeism. Students absent from class for any reason are still responsible for all work missed.Instructors have the right to determine whether work missed can be made up and have the liberty to set reasonableexpectations for attendance based on frequency of class meetings and on the instructional delivery method, subject,type, and level of the class. Class attendance policies will be clearly stated for students by their respective instructorson separate documents (course outlines/schedules) or appendices to the master syllabus.

Course Withdrawal

Students may withdraw from a course without academic penalty until the midpoint of the term. Students withdrawingafter the midpoint of the term receive grades of WP Withdrawal Passing, or WF Withdrawal Failing. Students whostop attending class(es) without formally withdrawing risk earning a final grade of F, which will appear on the academictranscript. Withdrawing from a course may impact financial aid status, academic standing, and GPA.Refer to the ATCCatalog and Student Handbookfor further details.http://www.athenstech.edu/Catalog/

Course Technology

Course addendum will provide details concerning the use of technology in the course. Course schedule types includeweb-enhanced taught face-to-face; online taught online using the internet, may require proctored exam; hybrid class time is split between face-to-face and online; video conference taught at two or more campus locationssimultaneously with instructor located at one of the classroom locations.
