The 19 highest-performing countries involved in the Program for International Assessment vary widely on most teacher policies, but they do have three practices in common, finds a study by the Organization for Economic Development and Cooperation.
All the highest-performing countries, including the United States, had:
• A required, extended period of “clinical practice” during the preservice period or at the beginning of the teacher’s career;
• Opportunities for professional development tailored to individual teachers; and
• Teacher-evaluation practices that prioritize continuous improvement.
