The free public school system is paralleled in many areas by private and parochial schools. Preparatory schools are private schools operated primarily to prepare students for college. They correspond to English public schools, which are in fact private, endowed institutions. The English system, which is roughly organized according to a six-six model, has been used as the basis for many school systems in developing countries. These educational systems usually provide primary education for children up to ages 11 or 12 and a secondary program for students up to age 18.
