How can the supervision process be used to help successful and experienced teachers get better at what they do? Way too often I hear teachers at conferences and in-services complain, “I already do that. That won’t work, you don’t know my students. I could’ve written the book on this.” Many honestly believe that after teaching for a certain number of years that they have little new left to learn. I believe that this is a dangerous way of thinking. As Collins asserts, the minute you think you have arrived is the moment you begin to slide backwards.

Unfortunately, professional development for teachers has been a “one-size- fits- all” mentality for a number of years. Just as we realize the importance of differentiating for students in order for successful learning to occur, we need to transfer this understanding to professional development and learning for teachers. We must meet the needs of all teachers so that all teachers can continually improve their instruction. When you are improving instruction, you are impacting student achievement and learning.
