About public school:
In the United States, the standard school system developed from an uncoordinated conglomeration of dame schools, reading and writing schools, private academies, Latin grammar schools, and colleges into a well-organized system in which a child may progress from kindergarten to college in a continuous and efficient free public system. By 1890 there had evolved the now common twelve-grade system whereby the child enters kindergarten at the age of five, goes to grammar or elementary school for grades one through eight, high or secondary school for grades nine through twelve, and then enters college. Compulsory attendance at school has been legislated in all states, although standards of age and length of the school year vary considerably.
