The International Federation of Secondary Teachers (French: Fédération internationale des professeurs de l'enseignement secondaire officiel, FIPESO) was a global union federation bringing together trade unions representing secondary school teachers.
The federation was established in 1912 at a meeting in Brussels attended by unions from France, Belgium and the Netherlands.
After World War II, the federation also began campaigning on professional and social topics.
[1] In 1952, FIPESO, the IFTA and the WOTP merged to form the World Confederation of Organizations of the Teaching Profession.
