Top teachers can increase student performance, but...?

The transfer of top elementary teachers to low-achieving schools can help boost students' performance, but there's a catch: getting them to agree to move.

A new study, seven years in the making, finds that elementary teachers identified as effective who transferred to low-achieving schools under a bonus-pay program helped their new students learn more, on average, than teachers in a control group did with their students. They also stayed in the schools at least as long as other new hires. (Stephen Sawchuk at Education Week)
