The International League of Esperanto-Speaking Teachers (Esperanto: Internacia Ligo de Esperantistaj Instruistoj, ILEI) is a non-governmental organization with the goals of teaching respect for humanity, life and nature and seeking to further mutual understanding among peoples.
Specifically, ILEI is a special interest group affiliated with both UNESCO and the Universal Esperanto Association (UEA).
It aims to introduce the Esperanto language into schools at all levels; to teach Esperanto across all subject areas and levels; to research and solve pedagogical problems in language education; to publish modern tutorials, magazines, books and pamphlets; to organize international conferences and seminars, etc.
; to oversee international exams for certifying individuals' abilities in speaking and teaching Esperanto; to partner with governmental and educational institutions, as well as with other organizations whose goals accord with those of ILEI; and to establish and maintain websites and discussion lists to further these aims.
Founded in 1949, the first executive council included Violet C. Nixon, (United Kingdom, president), Einar Dahl (Sweden, secretary-treasurer), Jeanne Dedieu (France) and P. Korte (Netherlands).
