Our faculty handbook states:
Each faculty member must maintain a grade book for all classes. The grade book must be maintained electronically using Blackboard Gradebook. The grade book should reflect a record of the student’s course progress as set out in the course syllabus, including the final grade achieved. Student grades should be entered within 1 week of the student’s assigned submission date. All hard copy grade books and/or Excel grade book files on CD must be surrendered to the director of registration and records upon termination of employment (Athens Technical College, p. 30)
