IHWO: More Than 60 Years Of Competence

The International House World Organisation / IHWO was founded in 1953 with the goal of raising standards of language schools and language courses. IHWO is reputed to be the oldest and largest network of language schools worldwide, with 150 member schools in 50 countries on all 6 continents.

IHWO stands for high teaching standards in modern languages and has an excellent reputation in training language instructors. Those who choose to be instructed at an ih-school can be sure to have made an excellent choice.

All IHWO schools operate according to the IHWO guidelines and are inspected regularly. The primary key to quality language instruction is highly qualified teachers. To maintain this standard, ih offers numerous continued-education training courses to its instructors in a classroom format as well as online. The ih Certificate / IHC in particular has gained international recognition, and is comparable to the Cambridge CELTA for English language instruction. In the meantime, the IHC is available for numerous other languages.

Ih-teachers have been authors of numerous language instruction textbooks such as: Headway, Language to Go, Cutting Edge, Natural Grammar and Fountain.

The work of IHWO covers the following areas:

  • Training & the continued education of language instructors
  • Organising conferences & workshops
  • Development of standards for quality language instruction
  • Support of member schools


Why Join IHWO? 

Membership in IHWO is a guarantee of professional instruction and high quality language courses, from actual instruction to the care and attention provided to students; from ongoing teacher-training to equipment and facilities.

Striving for Quality

A potential school must be inspected and meet the high IHWO standards before it may become an affiliate of the organisation. In this way students and instructors can rely on the name IHWO.


ih partner schools profit from the exchange of ideas and contacts within the network. Close co-operation often develops between members. Annual conferences (such as the Directors' Conference, the Young Learners' Conference, or the Directors of Studies conference), ih workshops, ih road shows and mutual representation at education fairs also take place.

Educational material, advertising and administrative materials are available to all ih-member schools.
