Creating and sustaining a collaborative culture takes work, effort and focus. If professional development delivered in the classrooms is to be successful, the focus and practice must become part of the school culture (Danielson, 2002). Providing in-classroom professional development has been the key to instructional reform at Lee Richmond Elementary School in Hanford. The school was identified as an underperforming school by the Public Schools Accountability Act of 1999. In response to the designation, the entire school team worked to create a collaborative learning culture. In this article, the author focuses on building a culture of meaningful learning for adults as well as children at Lee Richmond School. As principal, the author also focuses the collaborative culture by creating and sustaining the professional atmosphere necessary to support in-classroom staff development of the school.
