The role of the principal has become increasingly complex and challenging. Recent emphasis has been placed on the role of principals as leaders who can build a culture of learning in schools to close the student achievement gap. Outside factors such as fast-growth in Texas have caused schools to change and grow quickly, which increases the learning demands placed on principals as they seek to develop the knowledge and skills needed for effective leadership. Developing and sustaining a professional learning community is a powerful strategy that has been found to improve teaching and learning, however developing professional learning communities requires skilled leadership. Limited research exists regarding how principals learn to implement and sustain professional learning communities within fast-growth districts, therefore, with this phenomenological qualitative research, I explored the lived experiences of seven principals within one fast-growth district in Texas to explore how they learned to develop and sustain a professional learning community.
