International TEFL and TESOL Training - ITTT

What International TEFL and TESOL Training - ITTT does

International TEFL and TESOL Training (ITTT) is a privately held teacher-training organization founded in 1998 that delivers TEFL and TESOL certification to individual learners seeking to teach English abroad or online. The company offers a tiered product portfolio spanning a 120-hour basic online certification ($249) up to a 550-hour Expert Diploma Package ($599), plus four-week in-class intensive courses at training centers in over 30 countries ($1,490-$2,290) and hybrid combined courses blending online theory with short in-person practice. The platform is a web-based learning management system delivering self-paced video lessons, tutor support, and a 30-hour optional teaching practicum; certificates are validated through partnerships with Lamar University (Texas) and Siam Technology College (Bangkok), enabling credit transfer toward B.Ed and M.Ed degree pathways.

ITTT's go-to-market is direct-to-consumer and self-serve via its website (teflcourse.net), augmented by content marketing, social media, third-party review platforms (Trustpilot, Reviews.co.uk), and affiliate partnerships with education listing sites (GoAbroad, ESLbase, Go Overseas). Revenue is generated through one-time course fees across pricing tiers, with a complementary distribution channel of physical training centers acting as both a higher-priced SKU and a credibility anchor. The company claims 100,000+ graduates across 100+ countries, lifetime job-placement assistance, and a 9.7/10 average review rating, but discloses no financial metrics, no AI capabilities, and operates with 51-100 employees across offices in the USA, UK and Thailand with operational roots in Phuket.

Operationally ITTT sits at the intersection of education content delivery and global labor-market intermediation, monetizing the demand from non-native and native English speakers seeking internationally portable credentials. The business model is asset-light online delivery layered with a partner-leveraged physical training footprint, and growth depends on continuous top-of-funnel demand generation in a fragmented global TEFL market where credentials are largely unregulated and competition is predominantly digital.

Broad incumbents

• Coursera: Online learning marketplace offering TESOL-related specializations and certificates from universities. Comparable to ITTT as an online channel for TEFL-adjacent learning, but Coursera is a broad incumbent in online higher education rather than a TEFL certification specialist; represents a potential substitute channel for aspiring teachers.
• EF Education First: Global education company with language schools, online platform (EF Hello), and teacher training programs. Comparable to ITTT at the intersection of English language learning and teacher training, but operates as a broad incumbent across language travel, academic programs, and corporate training rather than a TEFL-specialist.

Direct peers

• i-to-i TEFL: Long-established online and in-class TEFL provider offering 120-hour+ certifications with job placement support. Comparable to ITTT on the self-paced online course model, international training locations, and target audience of career-changers wanting to teach abroad.
• Oxford TEFL: TEFL certification provider offering online and in-person CELTA and TEFL courses with centers in multiple countries. Comparable to ITTT in international in-class delivery, CELTA offering, and target segment of qualified and aspiring English teachers.
• TEFL Org: Online and in-class TEFL/TESOL certification provider with government-regulated Level 5 qualification status. Directly competes in the same 120-hour online certification category and targets the same 'teach English abroad' customer segment as ITTT.
• Bridge Education Group: TEFL/TESOL certification provider and teacher placement company with both online and in-person programs. Comparable to ITTT in offering combined certifications (TEFL + specialized), credit-bearing programs, and a global teacher recruitment marketplace.
• The TEFL Academy: UK-headquartered TEFL certification provider offering 120-hour online and in-class courses, government-regulated and Ofqual-recognised. Directly comparable to ITTT in core product, target customer (aspiring English teachers), and tiered online pricing model.
• International House: Globally established CELTA and TEFL training network with in-class training centers in dozens of countries. Directly comparable to ITTT's international training center footprint and CELTA offering, and overlapping in the same aspiring-teacher customer base.
• Premier TEFL: Online TEFL certification provider offering 120-hour and longer courses with job placement assistance. Closely aligned with ITTT on direct-to-consumer self-serve model, online course delivery, and graduate recruitment support.

Emerging players

• The Language House TEFL: Smaller TEFL training provider with in-class 4-week intensive programs in Latin America. Comparable to ITTT on intensive in-class training format but with a narrower geographic footprint and less developed online course portfolio.
