An international school is a school that promotes international education, in an international environment, either by adopting a curriculum such as that of the International Baccalaureate, Edexcel or Cambridge International Examinations, or by following a national curriculum different from that of the school's country of residence.
These schools cater mainly to students who are not nationals of the host country, such as the children of the staff of international businesses, international organizations, foreign embassies, missions, or missionary programs. Many local students attend these schools to learn the language of the international school and to obtain qualifications for employment or higher education in a foreign country.
A Junior School is a type of school which provides primary education to children, often in the age range from 8 and 12, following attendance at Infant school which covers the age range 5-7. (As both Infant and Junior Schools are giving Primary Education pupils are commonly placed in a unified building housing the age ranges of both Infants and Juniors - a Primary school).
A Secondary School or a High School is both an organisation that delivers level 2 junior secondary education or level 3 (Upper) secondary education phases of the ISCED scale, and the building where this takes place. Level 2 junior secondary education is considered to be the second and final phase of basic education. Secondary schools typically follow on from primary schools and lead into vocational and tertiary education. Attendance is compulsory in most countries for students between the ages 11 and 16. The systems and terminology remain unique to each country.
A Boarding School is a school at which most or all of the students live during the part of the year that they go to lessons. The word 'boarding' is used in the sense of "bed and board," i.e., lodging and meals. Some boarding schools also have day students who attend the institution by day and return to their families in the evenings.
Many independent (private) schools are boarding schools. Boarding school pupils (a.k.a. "boarders") normally return home during the school holidays and often weekends, but in some cultures may spend most of their childhood and adolescent life away from their families. In the United States, boarding schools comprise various grades, most commonly grades seven or nine through grade twelve—the high school years. Other schools are for younger children, grades two through eight. A military school, or military academy, also features military education and training. Some American boarding schools offer a post-graduate year of study to help students prepare for college entrance, most commonly to assimilate foreign students to American culture and academics before college.
