Every year, American public schools spend $2.2 billion replacing teachers who leave the profession.
But the true cost to the system is even bigger. When teachers stick with their jobs, they build up valuable experience and improve their instructional techniques. When they leave, that valuable experience vanishes. Administrators have to expend time and money – both usually in short supply – training replacements.
Retaining teachers, therefore, could save billions and improve education quality.
Fortunately, preserving the intel experienced teachers have isn’t that difficult. It’s as simple as mimicking the stat geeks who are revolutionizing baseball and the political operatives who are winning elections.
