Bill Gates re NY's release of teacher "value-added rating": public shaming of teachers won't improve teaching. On that, he's right. But knowing the score on a high-stakes student standardized test won't improve teaching either. Where is the emphasis on professional development and the teacher's own work as part of a team dedicated to improving everyone's craft? Data only provides an incomplete picture.
For Teachers, Shame Is No Solution
Publicly ranking teachers by name will not help them get better at their jobs or improve student learning.
