This document discusses Finland's education system as a model for professional learning communities. It provides 3 key aspects of Finland's approach: 1) Trusting and autonomous teachers with strong preparation. 2) A focus on formative assessment and vertical alignment from preschool to university without dead ends. 3) National curriculum frameworks and a focus on developing competencies rather than test scores. The document suggests US educators could learn from allowing teachers to co-teach, have candidates do sample lessons, and giving teachers more autonomy in teams.
