The Mirage: Confronting the Hard Truth About Our Quest for Teacher Development

In this report, TNTP looks at challenges in the area of teacher improvement, and finds that large investments have been made by school districts and systems across the country in recent years in programs aimed at helping teachers develop and improve. TNTP focused on a sample of three large school districts and set out to identify supports that successfully boost teacher growth. The report finds little evidence that year-on-year improvements are taking place; moreover, researchers were unable to identify particular practices helping teachers who do demonstrate improvement.
