The world’s richest, private philanthropic organization, the Bill and Melinda Gates Foundation, over the past several years has heavily funded efforts to advance controversial Common Core educational standards across the country – including Massachusetts.

From a review of the funding dispersed, publicly available on the Gates Foundation Website, baystateparent estimates that over the past 13 years, the foundation made grants of more that $160 million to Bay State companies and nonprofits working in education, including several universities and two public school systems.

Nearly $36 million of that amount, baystateparent estimates, was given to Massachusetts companies and nonprofits either working on projects related to Common Core or those entities advocating for the new college- and career-ready standards.
