Top-performing systems realize the importance of deploying their teachers wisely. That’s why Japan, South Korea and Singapore rotate teachers’ school assignments periodically. This allows teachers to work with and learn from a broad range of their peers, experience different school contexts including those in rural and urban schools, and teach students with a diversity of cultural, linguistic and socioeconomic backgrounds. This also means that strong teachers can be assigned where they are needed most, giving the most challenged schools the staff they most need. In Singapore, teachers even rotate in and out of the Ministry of Education, where they can impact high-level policy decisions.
