There are practically as many philosophies of education as there are schools in the United States. There are the Prusso-American schools of Horace Mann’s age, there are the public schools of the No Child Left Behind era, there are parochial schools of varying denominations, there are different types of military, boarding, and prep schools, there are Montessori, Waldorf, and Classical schools, and there are even major differences in philosophy of education for styles of homeschooling.
