What TESOL (Teachers of English to the Speakers of Other Languages, Inc.) does
TESOL International Association is a nonprofit 501(c)(3) professional association founded in 1966 and headquartered in Alexandria, Virginia. It serves English language teaching (ELT) professionals worldwide, with 9,000+ members and an affiliate network of 93+ regional associations across more than 100 countries. The association's core mission is advancing the expertise of teachers who teach English to speakers of other languages, spanning PreK-12, adult education, and higher education segments.
The organization's core products include the annual TESOL International Convention & Expo (3,000+ attendees, 600+ sessions across 13 content areas), TESOL Press Bookstore (100+ titles), peer-reviewed journals (TESOL Quarterly, TESOL Journal), the myTESOL community platform built on Hivebrite, professional development programs (Preconvention Institutes, ELT Leadership Management Certificate Program, SWEL Coach workshops), and the "6 Principles" standards framework. Distribution runs through the website, myTESOL portal, the annual convention, and the global affiliate network, with corporate sponsorships and exhibitor packages generating additional revenue. Recent additions include digital subscription products (ELT EdTech Toolkit at $60/6-month, TESOL Connections newsletter) and on-demand certificate courses.
The business model is diversified across member dues (Individual, Student, Global, Retired tiers), convention and event registration, publications and bookstore sales, corporate sponsorships across tiered packages (Sapphire, Emerald, Ruby), advertising through Naylor Association Solutions, and online courses. With 51-100 employees and no public funding rounds or M&A activity, TESOL operates as a stable, member-funded professional association. Its 2026 product launches, including the ELT EdTech Toolkit, an AI-Enhanced ELT book, and Microsoft/CAST co-developed resources, signal a deliberate expansion of its digital and recurring-revenue product surface beyond the convention-centric legacy model.
