Betsy DeVos, the new U.S. Secretary of Education, has a reform agenda to advance school choice. Her track record includes enabling charter school growth in Michigan at taxpayers' expense with little oversight or accountability. Although an effective advocate, DeVos represents a broader policy movement to privatize American education, much of it happening beneath public awareness. Understanding Ms. DeVos's policy goals, how the President and Congress are supporting these, and how privatization is occurring in states can help principals and education leaders recognize the stakes, learn what to watch for, and take appropriate actions to preserve and strengthen America's public schools.
