It's difficult to comment on situations where you weren't present when oral feedback was given, but if the HT is absolutely sure that feedback of this kind was given, then it needs to be challenged by the head. In team meetings, the HT is given every opportunity to raise issues, including where feedback has been less than helpful. In no way do I want to question what your colleagues say. However, often things are said as part of the feedback that raise eyebrows, such as the 'tear to eyes' comment and it's these things that staff remember. Out of context, it's just silly of course, but there is always a sound pedagogical reason why learning and progress is graded as good, satisfactory or outstanding. The evidence base will need far, far more than 'it didn't bring a tear to my eye'. In fact there's no way that such a comment would appear on an evidence form.
