Teaching team do not improve their practice or teach to mastery

Teacher Grace has been teaching for many years and is comfortable with her current practice. She does not see the benefit of participating in coaching, particularly at this point in her career. Grace knows that her delivery of the effective teaching techniques used in the programs could be improved but most of the students in her class have a firm understanding of the content, even though she frequently must go back and reteach some parts of the lesson to ensure all students are at mastery. Grace does not participate in coaching and her effective teaching practice remains the same. As a result, Grace does not improve her ability to teach to mastery.
