These are critiques that come also entirely from those who are embedded within the entrenched public education system and who have a stake in maintaining and expanding the status quo. Some senators seem aghast at the idea that DeVos was unfamiliar with all sorts of federal laws about how local schools are required to behave in order to receive federal funding.
But this just puts DeVos on the same footing as everybody outside the education system who have to interact with it and feel little control. While there are indeed parents who are familiar with these federal regulations because they have kids with special needs, this approach on DeVos feels very much like an attempt to keep the Department of Education under the control of insiders.
