My initial reaction to this is based on several other posts I made earlier. The focus seems to be to assume an instructor is doing a good job unless you somehow find out otherwise, after which will follow an investigation and punishment. As I said earlier, the trend in businesses today is exactly the opposite--assume all instructors can use help and implementing a non-threatening program of continuous improvement. I know that is an outlier position, but it might be interesting to toss the idea around for a while.
