The Office of School Leadership provides professional development opportunities which build upon the expertise of local leaders to connect theory with practice. A key to successful growth is the Marzano Leadership Framework which serves as the foundation for monthly collaborative learning opportunities that include practical application in a leader to leader approach. Moving beyond simulations, we create authentic collaborative learning opportunities in the form of Instructional Rounds, reflective practices as part of Instructional Reviews, and analysis of student performance data as it relates to improving and planning for effective instruction.
