The report notes teacher turnover has consequences for student achievement and poses an expensive financial burden for schools.
Indeed, districts around the country struggle to retain teachers, and the problem is getting worse. In the 2011-12 school year, 3.1% of schools reported they could not fill a vacancy. By 2015-16, that number climbed to 9.4%.
Once a district secures a teacher, however, retaining them becomes another concern. In a 2018 Gallup poll, 61% of superintendents said teacher retention is their greatest struggle. In 2017-18, almost every state had teacher shortages, and nearly 50% of teachers were looking for different jobs.
