Researchers have documented many characteristics of inspiring and effective leaders:
In much the same way as a painter carefully combines the colors of the palate to create a background from which the painting emerges, the teacher creates a culture that serves as the setting for the emergence of a vital professional learning community. The role of the leader as culture builder carries new responsibilities that often read more like poetry like a traditional job description. An effective leader creates sparks, marshals forces, tends fires and celebrates victories, believes in and releases the potential of followers, and unites dynamic and diverse communities for the good of the whole (Wald & Castleberry, 2000, p. 19).

Five qualities are critical to building and sustaining professional learning communities:

Vision
Vision refers to the future-focused quality of leadership that is necessary in creating a meaningful context for action. Future-focused leadership is the ability to look beyond the present circumstances and “conjure an image of the future that recognizes and responds to the need for change” (Wald & Castleberry, 2000, p. 20). Building a school vision answers the question “What do we hope to become?”. DuFour & Eaker (1998) state that “until educators can describe the ideal school they are trying to create, it is impossible to develop policies, procedures, or programs that will help make that ideal a reality” (p. 64). The school vision is not solely created by the school leader but “is created by the school community” (DuFour & Eaker, 1998, p. 64). There are a variety of ways to develop a vision statement: telling (the leader tells); selling (the leader provides); testing (the leader gets reactions to help refine and redesign the vision statement); consulting (a representative committee develops a statement for the leader to approve); and co-creating (a collaborative process where all stakeholders build a shared vision) (DuFour & Eaker, 1998, p. 65). A vision will have little impact unless ownership is established. Thus, although co-creating is the most time consuming, it is also most likely to result in a shared vision critical to professional learning communities. “A vision becomes the community’s road map to the future” (Wald & Castleberry, 2000, p. 20). It motivates and energizes people, provides direction, creates a pro-active organization, and sets a clear path for action. To sustain this energy, the leader must “hold the vision high for all to see”, constantly revisit it, expand upon it, and continuously help members of the community connect with it (Wald & Castleberry, 2000, p. 20).

Values
“Leaders, by their words and actions, are the keepers of values” (Wald & Castleberry, p. 20). They are then able to welcome the values and beliefs of the members of their school community, help them to unveil their common values, and then define what they value collectively. These values then become the moral and ethical foundation for the leader and school, and guide their decision making. The role of the leader is to then ensure that values are transformed into action. Value statements should be few in number, direct, clearly linked to the vision statement, focused on behaviors and should commit the staff to action.

Service
A service-based leader acts as a steward to the mission, vision, and values of the organization and to its individual members. According to Block (1993), stewardship is the willingness to be accountable for the well being of the larger organization by operating in service, rather than in control, of those around us. In schools, principals establish infrastructures that make it possible for staff to reach their potential and advance the vision of the school. The principal provides resources, plans for ongoing collaboration, eliminates unnecessary obstacles, engages the public community, and protects the integrity of the school (Wald & Castleberry, 2000).

Capacity Building
A school is unable to realize its vision without expanding the skill and knowledge base of its staff. A quality leader encourages risk taking and offers a non-threatening environment in which staff can learn, grow, and change. Leaders also must consider ways to facilitate school-based, collaborative groups and be able to align new practices with the school vision.

Relationship Building
The image of the leader as a hero is changing, and an alterative image of leadership is emerging: the leader as an architect of relationships. “In this capacity, the leader designs a workplace where relationships are primary, where a sense of belonging and trust is pervasive, where diversity is valued, and where connections are open and active. Creating an atmosphere of belonging is a primary role of a leader” (Wald & Castleberry, 2000, p. 27).

These five qualities of effective educational leadership (vision, values, service, capacity building, and relationship building) are central in building professional learning communities. In reality, there is an exhaustive list of specific traits common among effective leaders, and the list continues to change, as does the demanding role of the principal. Transforming schools into professional learning communities demands quality and committed leadership that encourages the intentions of the community to become the reality.
