TNTP's Major Findings in new report, "Confronting the Hard Truth About our Quest for Teacher Development"

• Districts are making a massive investment in teacher improvement—far larger than most people realize. We estimate that the districts we studied spend an average of nearly $18,000 per teacher, per year on development efforts.
• Despite these efforts, most teachers do not appear to improve substantially from year to year—even though many have not yet mastered critical skills.
• Even when teachers do improve, we were unable to link their growth to any particular development strategy. 
• School systems are not helping teachers understand how to improve—or even that they have room to improve at all.
