Green Acre Bahá'í School is one of three leading institutions owned by the National Spiritual Assembly of the Bahá'ís of the United States. The name of the site has had various versions of "Green Acre" since before its founding in 1894 by Sarah Farmer and is a conference facility in Eliot, Maine, in the United States. It had a prolonged process of progress and challenge while run by Farmer until about 1913 when she was indisposed after converting to the Bahá'í Faith in 1900. `Abdu'l-Bahá, then head of the religion, visited there during his travels in the West in 1912. Farmer died in 1916 and thereafter it had evolved into the quintessential Bahá'í school directly inspiring Louhelen Bahá'í School and Bosch Bahá'í School, the other two of the three schools owned by the national assembly, and today serves as a leading institution of the religion in America. It hosted diverse programs of study, presenters, and been a focus for dealing with Racism in the United States through being a significant venue for Race Amity Conventions (later renamed Race Unity Day meetings) and less than a century later the Black Men's Gatherings and further events.
A Bahá'í school at its simplest would be a school run officially by the Bahá'í institutions in its jurisdiction and may be a local class or set of classes, normally run weekly where children get together to study about Bahá'í teachings, Bahá'í central figures, or Bahá'í administration. Bahá'í topics may be minimized in favor of a general curriculum, often with an internationalist form, with accreditation from a variety of sources.
Foremost among them are Green Acre, the "paradigmatic of a Bahá'í institution", was founded in 1894 for exploring religious diversity seeking unity, and the first Bahá'ís appearing there in 1901. It came officially under Bahá'í management institutionally from 1916 after several years of promoting Bahá'í ideas under Sarah Farmer. As a Bahá'í institution it began to inspire other regional schools in the United States for the religion: first came Bosch Bahá'í School becoming more formally a Bahá'í school in 1927 and another in 1931 at Louhelen Bahá'í School.
