Diane Ravitch's New Group On Wednesday morning, a group of education activists across the country -- including Leonie Haimson, Anthony Cody, and Diane Ravitch, the fierce historian-cum-reform-fighter -- announced the launch of the Network for Public Education. The group aims to fight off state advocacy groups such as StudentsFirst and Democrats for Education Reform that push a particular school-related agenda including charter schools and teacher evaluations based, in part, on student test scores.
