What Language Testing International does

Language Testing International (LTI), founded in 1998 and headquartered in Tarrytown, New York, is the exclusive global licensee of ACTFL (American Council on the Teaching of Foreign Languages) assessments and operates as a private for-profit company with 101-250 employees. The company delivers standardized language proficiency testing across more than 120 languages and 60+ countries, serving U.S. federal agencies (including the Departments of Homeland Security, State, and Defense, and the Defense Intelligence Agency), dozens of Fortune 500 corporations, K-12 schools and state education departments, higher education institutions, and individual professionals. Its product suite comprises 11 ACTFL assessments covering speaking, writing, listening, and reading proficiency, with scores aligned to ACTFL, ILR, and CEFR scales and ACE-recommended for college credit.

LTI's technology stack combines web-based delivery, remote AI-monitored proctoring, computer-adaptive testing (L&Rcat), avatar-driven spoken prompting (OPIc), and a mix of human-rated scoring by ACTFL-certified raters with NLP-based automated scoring for selected writing tasks. The LTI Client Site serves as the enterprise ordering and results portal, while individual consumers transact directly via the e-commerce site. Revenue is generated through per-test purchases by individuals and quote-based subscription contracts with organizations, schools, and government agencies, supported by ancillary services including digital badges via Credly and adjacent global learning programs through the 2019 acquisition of Level Up Village.

The business is differentiated primarily by the regulatory and brand moat of its exclusive ACTFL license, its entrenched position in U.S. government language testing standards (ILR), and a long-standing reputation evidenced by over 5 million test takers certified and 1 million tests administered annually. Recent strategic emphasis includes AI-driven scoring development, WCAG 2.1 AA accessibility compliance, and an internal CEO succession to Kim Sallee in March 2026, with prior focus on assessment product development.

Scale indicators10 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Educational Testing Service (ETS): Administers the TOEFL family of English proficiency tests, the most widely used English-language proficiency assessments for university admissions and government use. Directly comparable to LTI as a large-scale, standardized language proficiency testing provider with global reach.
• Pearson: Administers the PTE Academic and PTE General English proficiency tests accepted by universities, governments, and employers worldwide. Competes head-to-head with LTI's Test of English Proficiency (TEP) and other English offerings in the high-stakes assessment market.
• British Council / Cambridge Assessment English (IELTS): Co-owners of IELTS, one of the world's most widely accepted English proficiency tests for immigration, higher education, and employment. Comparable to LTI as a globally scaled, multi-purpose language testing provider with strong government and academic adoption.

Emerging players

• Duolingo English Test: AI-driven, on-demand English proficiency test accepted by thousands of institutions. Represents the AI-native, low-cost disruption vector that LTI's traditional human-rated assessments must increasingly compete against on price and turnaround.
• Vericant: AI-supported speaking and English proficiency assessment used by international student admissions. Comparable as a digital-first, AI-enabled language assessment targeting university admission — directly overlapping with parts of LTI's higher-education use case.
• EF Standard English Test (EF SET): Free, online, CEFR-aligned English proficiency test used by employers and institutions. Comparable as a digital, lower-cost proficiency alternative — relevant for LTI's positioning as low-friction AI/web-based entrants enter the market.

Broad incumbents

• Berlitz: Global language training and assessment provider with corporate, government, and consumer programs. Comparable as a broad incumbent offering language proficiency services (training plus testing) to enterprise and government clients similar to LTI's commercial segment.
• Rosetta Stone: Consumer and enterprise language-learning platform with assessment components. Comparable as a language-skill brand operating across consumer, education, and enterprise channels; less specialized than LTI in high-stakes proficiency certification.
• College Board: Administers SAT, AP, and other K-12 and higher-education assessments including world language AP exams. Comparable as a U.S. education assessment incumbent whose framework decisions influence K-12 and higher-ed language assessment demand relevant to LTI.

Others

• Prometric: Global test delivery and remote proctoring provider. Comparable as both a proctoring partner to LTI and as an adjacent infrastructure player in high-stakes assessment delivery — relevant for ecosystem positioning rather than direct product competition.
