By far the most difficult part of my job as an instructor is developing and maintaining valid, fair, reliable, repeatable methods for grading students in our Restaurant Guest Service class. It's a class where there is a small bit of knowledge that can be tested for via written exams but most of it is Skills Application on a daily basis and a working restaurant where the person in charge is always pulled in 6 directions is a difficult place to closely monitor students activities and mastery of the techniques and methods I teach. Can you give any feedback on this or ideas on how I can effectively evaluate a class of 15 students simultaneously while still performing the other demands of my job? Thanks in advance.
