I am a teacher in a Magnet School of the Arts. I work in the Fine Arts Department. My evaluating administrator often gives me a Needs Improvement rating on Knowledge of Content. I am extremely knowledgeable about the subject I teach, and could not disagree more with her. I have spoken to her several times to ask what I need to do in order to receive a proficient in this category, and she cannot give me a definite answer. She says something to the extent of "I don't know much about your subject, but there has to be more to it." I have spoken to my principal about the matter, and his response is no better. He also states that he "doesn't know much about it either, and he'll try to find one who does to help me." What should I do in this situation, and how do I get them to understand that I know what I'm doing. My students show significant gains each year on the SLO Assessments, but that does not seem to be enough.
Your suggestion is perfect. I often feel the same amount of confusion from my own administrators because I teach Pre-K in the public school system. More often than not they do not know about or understand the expectations or standards involved with the Pre-k curriculum which can cause confusion. There needs to be understanding, and a knowledge base in order for an evaluator to make a judgement. Providing documentation and proof to support your teaching is an excellent idea.
You are totally right
Great solution to this problem! To expand a bit on this solution, I would recommend also pointing out the standards for each lesson being observed. The standards themselves act as evidence that there is a subject to be knowledgeable on.
