"Ed schools, such as Teachers College at Columbia, or Penn’s Graduate School of Education, have trained and certified most of the nation’s public-school teachers and administrators for the past half-century. But in the past 20 years especially, ed schools have been offering advanced degrees in things like 'educational leadership', 'higher education management', and just 'higher education' to aspiring college administrators. And this influx of ed school trained bureaucrats has played a decisive role in pushing an already left-leaning academy so far in the direction of ideological fundamentalism that even liberal progressives are sounding the alarm."
