Over the years, various research studies have suggested that teachers have the greatest school-based effect on student achievement. In recent years, however, the crucial role of principals has also been made clearer by research. So, how does principal turnover harm students?
The turnover rate for principals is higher than nearly any other white-collar profession, with half leaving their school after three years and fewer than 30 percent remaining at a single school for more than five years.

The report estimates that reducing principal turnover by 25 percent could save the public school system $163 million a year – and might even boost student achievement.
