Elizabeth Warren has a commendably progressive platform on most issues. But her past approach to public education has been closer to that of free-market reformers than most people realize.

The Massachusetts senator’s track record on education has received little scrutiny. Not only was Warren until recently a proponent of market-driven education reform and so-called teacher accountability, but her current platform silences, staff appointments, and political equivocations raise questions about her commitment to reversing the billionaire-funded onslaught against public schools.

To her credit, Warren’s talking points this campaign season have been good so far. She has spoken about the need to raise teacher salaries, reinvest in early and K-12 childhood education, and cut student debt. And in the last national debate, Warren highlighted her one-year stint as a teacher, vowed to appoint a public school educator to the position of secretary of education, and declared that “money for public schools should stay in public schools, not go anywhere else.”
