I think it is important for principals to get feedback from their staff. There is a district survey sent in the Spring of each year. I like to know the pulse of my building or teachers more often than just the end of the year.
There are "Burning Questions" for 3 times a year. These are questionnaires I have used at the beginning of the year before school starts, mid-year, and one for the end of the year.. A blank sheet is included for you to generate your own questions if you'd like.
You could also convert this to a Google Form if you are familiar and use my questions in a Google From that you would design.
