Betsy DeVos has been cheered and jeered like no other U.S. education secretary.

Proponents of school vouchers herald her as the person who will finally usher in a new era of education, one in which the nation’s poor children will leave failing public schools for private or religious schools, and pay the tuition with federal dollars. DeVos has long been a voucher advocate.

Public school proponents are terrified that instead of working to fix problems in public education, DeVos will either dismantle it or put the brakes on federal oversight, letting the public school system slowly fall apart. DeVos has held no position in a public school, has never attended a public school and did not send her children to public school.

When feelings run high, misinformation tends to spread. So here is a partial list — a mini primer — of some things DeVos can and cannot do in her new job. It is not exhaustive, nor does it delve into ways the Trump administration could work around the education department’s limited role to enact its agenda.
