Building an improved professional culture is possible by developing teachers’ capacities to work with teacher teams on shared beliefs, academic focus, and productive relationships. — Jon Saphier, Matt King, & John D’Auria

Jon Saphier and colleagues have condensed a great deal of meaning into one sentence.

• Administrators and teacher leaders have a fundamental responsibility to create a professional culture that continuously improves teaching and learning for the benefit of all students and ensures that all members of the school community — students, parents, teachers, and administrators — are surrounded by supportive relationships.  Culture building is a challenging and never-ending task that cannot be delegated nor ignored.
• Leadership and teaching practices are shaped and sometimes determined by shared beliefs about students’ capacity for learning and teachers’ ability to successfully teach them.
• The primary means of continuous improvement is strong teamwork founded on trusting, productive relationships. Those relationships require constant tending to avoid the decline that is inevitable if they are ignored.

What, If anything, did Saphier and his colleagues overlook?
