The International School Nido de Aguilas

Nido at a Glance

Nido de Aguilas was founded in 1934 as a private, co-educational, non-sectarian, non-profit day school rooted in the best traditions of Chilean and North American education. Today, Nido serves over 1600 students from 50 countries and offers a comprehensive liberal arts, college preparatory educational program from Early Years (age three) through Grade 12. Nido serves the international business and diplomatic community of Santiago, as well as local students seeking an English-language, U.S.-style education. Current student enrollment is composed of 13% from the U.S., 47% from the host country Chile, and 40% from other countries.

All classes are taught in English except for Spanish language classes, which are required at all grade levels from Kinder 2 to Grade 12. Nido offers English-language acquisition support for students who do not have a high level of English proficiency, although entrance to Upper Elementary, Middle, and High School grades require prerequisite levels of English proficiency. The school offers limited learning support for children with learning differences.

The academic year comprises two semesters extending from late-July to December and mid-February to June. There is a five-week break during June and July, and the Southern Hemisphere summer vacation (semester break) runs from mid-December through mid-February.
