Rebecca Brooks Gruver of Hunter College described the book as "a comprehensive and [...] concise history" of how public schooling developed in a "common" fashion in the United States.

[3] Harvey J. Graff wrote that the book "is an elegant and admirable work of historical synthesis".

[5] Mitchell stated that the book is "a careful, detailed, and persuasive analysis" of how American education developed;[6] he criticized how the "treatment of regional variation" is a "serious weakness".

[7] Johann N. Neem of Western Washington University stated that the book had a strong role in showing light on the social history of American education, which had relatively little coverage before, and that the book "made sense for an era when Americans were losing faith in their institutions.
