Observation, Evaluation, and Feedback
As a Director, what is your role in the observation and evaluation process for your teams and teachers? Do you take on an evaluative or non-evaluative role, or perhaps a combination of both? How do you collaborate with principals in this process, and what strategies do you use to support and foster collaboration between teachers and support staff (especially when there may be reluctance from a teacher and it is not required by admin.)

At our school all mid-senior leaders divide the staff and take on non evaluative observation roles. It is more an attempt for coaching and supporting teachers' professional growth plans (all staff fill out growth plans at the beginning of the year). I will have support services staff as well as other teachers who I observe and provide feedback for at least twice a year formally, but monthly growth plan check ins.
If there are concerns with the teacher in any capacity, I would work with their supervisor - most likely the principal.
A big missing piece for our school is the training our leadership needs in conducting good observations, evaluating using a rubric (we have a rubric but no consistent rater reliability) and providing good feedback. I guess it is assumed if you have been moved to leadership, you know how to do this.
