A group of scholars at Indiana University led by Christopher Lubienski developed a methodology for ranking organizations and individuals in the field of education.
It was disheartening to see that nine of the ten most influential organizations advocate for school privatization, for charter schools and vouchers. It was also disheartening to see that these nine organizations have revenues in the millions of dollars each year. They are heavily funded by rightwing organizations and billionaires.
It was exciting, however, to see that #3 on the list of the 10 most influential organizations was the Network for Public Education!
It also was the organization with the smallest budget!

It is amazing what NPE can do with $302,000. It can advocate, act as an information clearinghouse and do independent research thanks to the skill and efforts of Carol Burris as well as some others. Unlike most of the right wing think tanks with budgets funded by billionaires, it cannot afford to lobby and purchase political will. Thanks to the hard work of NPE, it is one of the few organizations that examines the impact of privatization on local public schools. Unlike many of the groups funded by billionaires, NPE reports information instead of propaganda, distortion and hype. The budgets reveal what is truly a David versus Goliath scenario.
