The International House World Organisation (IHWO) is one of the largest and oldest groups of language schools in the world. Founded in 1953, IHWO is a global network of over 150 affiliated private language schools in more than 50 countries, spanning every continent. These schools are independent but commit to the IHWO mission of providing high-quality language education and teacher training. IHWO is renowned for its innovation in teaching methodology, particularly for English language teaching, and for its widely respected teacher training qualifications like the CELTA and Delta, which are issued in conjunction with Cambridge Assessment English. The organization champions high standards in education and school management and fosters an international community dedicated to linguistic and cultural exchange.
The London HQ serves as the central administrative and coordinating body for the global network of IH schools. Its functions include quality assurance, brand management, marketing, development of educational programs and materials, teacher training oversight, and providing support services to member schools.
The headquarters is located within LABS House, a modern co-working space known for its contemporary design, high-tech facilities, state-of-the-art meeting rooms, and collaborative environment.
The work culture at IHWO HQ is likely collaborative, international, and dynamic, reflecting its educational mission and its location within a modern co-working hub. There's a strong focus on professionalism, quality, and innovation in education.
The London HQ is the nerve center of the IH global network, crucial for maintaining consistent quality standards across all affiliated schools, driving strategic initiatives, and upholding the organization's international reputation for excellence in language education.
International House World Organisation supports a global network of approximately 150 affiliated language schools in over 50 countries. Functions supported globally include: setting and maintaining rigorous quality standards for language teaching and teacher training (e.g., CELTA, Delta), providing pedagogical support, professional development resources, and academic management guidance to member schools. IHWO also focuses on developing new educational products and services, managing international marketing and the IH brand, accrediting schools, and fostering a worldwide community of educators, staff, and learners dedicated to excellence in language education.
