ren, which began in the 1820s with the common (elementary) school. The movement gained incentive in 1837 when Massachusetts established a state board of education and appointed the lawyer and politician Horace Mann (1796-1859) as its secretary. One of Mann's many reforms was the improvement of the quality of teaching by the establishment of the first public normal (teacher-training) schools in the United States. State after state followed Massachusetts' example until, by the end of the 19th century, the common-school system was firmly established. It was the first rung of what was to develop into the American educational ladder. After the common school had been accepted, people began to urge that higher education, too, be tax supported. As early as 1821, the Boston School Committee established the English Classical School (later the English High School), which was the first public secondary school in the United States. By the end of the century, such secondary schools had begun to outnumber the private academies. The original purpose of the American high school was to allow all children to extend and enrich their common-school education. With the establishment of the land-grant colleges after 1862, the high school also became a preparation for college; the step by which students who had begun at the lowest rung of the educational ladder might reach the highest. In 1873, when the kindergarten became part of the St. Louis, Mo. school system, there was a hint that, in time, a lower rung might be added. Practicality allowed this change in the high school system. Schools now needed to ready the students for college -- an even higher form of education -- instead of preparing them to immediately enter the work force. America's educational ladder was unique. Where public school systems existed in European countries such as France and Germany, they were dual systems. When a child of the lower and middle classes finished his elementary schooling,...
