This report describes how teacher leadership is represented in the official documentation of key educational stakeholders in Alberta, Canada. Six themes emerged from the researchers' document analysis: foundational understandings; student diversity; innovative curriculum and student engagement; community engagement; 21st century competencies; and reflection and professional learning. Analysis of the idealized themes resulted in the identification of issues that may challenge teacher leaders. It is unlikely that teacher leaders can demonstrate competence in every theme area. Teacher leaders must necessarily prioritize some professional commitments in order to work sustainably. Several considerations were derived from the inherent tensions. The considerations were used to derive a composite profile of teacher leaders with the capacity to serve, influence, and thrive.
