What Teaching House does
Teaching House is a private, for-profit teacher training organization that delivers Cambridge Assessment English CELTA and DELTA qualifications to aspiring and practicing English language teachers worldwide. Founded in 2007 and headquartered in New York, the company operates approximately 19 training schools across the United States (New York, Chicago, Atlanta), the United Kingdom (London, Belfast, Oxford), Spain (Seville), Canada (Toronto), and Ireland, with delivery formats spanning face-to-face, fully online, and mixed-mode. The company is a subsidiary of Holmes Education Group, a diversified education conglomerate that also controls Oxford House, International House New York, Sol Group of Schools, and OHC Education Ireland. Teaching House's product portfolio centers on the Cambridge CELTA (initial teaching qualification) and DELTA (advanced diploma with three modules), supplemented by short professional development courses such as Effective Classroom Practices and Creative Methodology for Teachers of English. The Nomads Blog, free TEFL information sessions, free English classes, and a personality quiz support top-of-funnel lead generation and category authority in the English language teaching (ELT) space.
Teaching House's business model is primarily transactional and direct-to-consumer, generating revenue through one-time course fees paid by individual trainees seeking internationally recognized TEFL credentials. CELTA and DELTA pricing is quote-based rather than publicly disclosed, while short courses are priced at £340 GBP / $430 USD for one week and £630 GBP / $825 USD for two weeks. Short courses in London are approved for Erasmus+ funding (PIC 944411983), opening a publicly funded demand channel for European trainees. The go-to-market motion combines content marketing through The Nomads Blog, organic social presence across Facebook, LinkedIn, Instagram, and YouTube, free webinars and information sessions, downloadable lesson plans, and a global network of physical training academies that double as enrollment and brand-building assets.
Lizzy Adams serves as Director of Teacher Training and also as a Cambridge assessor, providing academic leadership across the global team of 18+ teacher trainers. Competitive positioning rests on being the self-described largest provider of CELTA globally, supported by a global affiliate network, real classroom teaching practice, and authorized Cambridge credentials. Customer concentration is low given the B2C, individual-trainee model with no disclosed enterprise or institutional anchor accounts.

Teaching House competitors and assessment
Company assessmentDirect peers
- International House: Network of language schools offering CELTA and DELTA across multiple countries. While IH New York is a sister entity within Holmes Education Group, the broader IH network operates as a direct CELTA delivery peer to Teaching House in overlapping geographies.
- TEFL Worldwide Prague: Authorized Cambridge CELTA training center based in Prague offering in-person CELTA courses. Comparable to Teaching House as an independent authorized center with similar course structure and target audience of aspiring English teachers.
- Oxford TEFL: Authorized Cambridge CELTA provider offering initial teacher training courses in person and online. Competes with Teaching House for aspiring English teachers globally, particularly in the online delivery segment.
- Oxford House (Holdings) Limited: Holmes Education Group affiliate offering professional development and club membership for ESL professionals in London. Sister entity to Teaching House with overlapping London ESL community, though different core service offering.
