A school is an educational establishment designed primarily to offer learning zones and learning opportunities for students under the tutorship of experienced instructors. Most developed countries have systems of formal primary education, which in some cases may be mandatory. In such instances, students progress from a single school to another, under the supervision of experienced instructors. In the United States, primary education typically consists of only public schools. Private schools, especially those founded for the purpose of providing a Christian education for its students, operate in relatively unstructured environments.

Private schools are generally funded either by tuition fees or other means, and students in such schools are expected to learn with the guidance of teachers from different fields. The curriculum is flexible, with a high emphasis on individual academic growth. The most common course of study in these schools is usually related to Christian studies, although courses in mathematics, science and history may also be offered. One distinguishing feature of this type of educational institution is that it maintains student records for a given period of time and assigns teachers a personal code number or key for communication purposes.

Charter schools, as opposed to traditional public schools, are privately owned and operated institutions, and students are allowed to attend for free. Students may choose any subject for which they feel comfortable, subject to approval by a teacher. An independent school board makes decisions concerning admissions, curriculum and personnel. Charters tend to be a great option for students who need extra support, especially those parents who do not possess the financial means to send their children to a traditional public school.
