Language Testing International background

Language Testing International was founded in 1992 in New York by Helen Hamlyn and Bob Katz to deliver the American Council on the Teaching of Foreign Languages (ACTFL) proficiency assessments to academic institutions, federal/state/local government agencies, corporate entities, and individuals. ACTFL, founded in 1967 with more than 10,000 members, produces the ACTFL Proficiency Guidelines and certifies testers and raters; LTI is its exclusive licensee and delivers the tests.

LTI began serving government agencies in 1998 and supports the Interagency Language Roundtable (ILR), a group of more than 30 federal agencies whose scale LTI reports on. Federal agencies buy through LTI's GSA schedule. Corporate testing has run for more than 25 years.

Today LTI tests more than 120 languages in more than 60 countries, administers more than one million tests a year, and has certified more than five million test takers. It has issued nearly 20,000 ACTFL digital badges through Credly since the badge program launched in 2021. Through its administration of ACTFL assessments, LTI also delivers official ACTFL language proficiency certificates, valued and industry-recognized credentials. LTI is the only company authorized to administer ACTFL assessments.

In 2016 the American Council on Education reviewed five ACTFL tests for credit by examination; recommendations were updated as of June 2024. LTI introduced validated machine scoring for Spanish AAPPL Presentational Writing and Interpersonal Listening and Speaking, and publishes an AI research library describing its approach.

Products and services

Proprietary data, methods or infrastructure

  • Exclusive license to deliver ACTFL assessments; only LTI can issue an official ACTFL rating.
  • A network of ACTFL-certified testers and raters who hold at least a master's degree, complete rater/tester training, attend annual meetings and recertify every four years.
  • A remote proctoring platform, a client site for ordering, scheduling and reporting, and the AAPPL student portal (aappl2.actfltesting.org).
  • Machine scoring models trained on human-rated responses and validated against unseen human ratings, with human adjudication when scores disagree.
  • More than 50 years of ACTFL research and more than three decades of published independent validation studies; LTI publishes a bibliography and an AI research library.

What makes Language Testing International different

  1. It is the only source of official ACTFL proficiency ratings, the U.S. standard scale for language ability.
  2. Its ratings are recognized outside the buying organization: by federal agencies and the Defense Language Institute, 27 state teacher-licensing systems, Seal of Biliteracy programs and the American Council on Education.
  3. It covers more than 120 languages, including many less commonly taught languages, on the same basis as Spanish, French and German.
  4. Speaking and writing are rated by ACTFL-certified raters; reading and listening are auto-scored for fast results, and machine scoring is validated and backed by human review.
  5. Results report on the ACTFL, ILR or CEFR scale, so one vendor serves HR, government and academic needs.
  6. No minimum order and no contract for organizational accounts; federal buyers can use the GSA schedule. Sourcewell contract 081225-LTG. Agencies can purchase through cooperative agreement with https://www.languagetesting.com/sourcewell

Language Testing International point of view

LTI's stated goal is to provide "a valid and industry-recognized language credential." It holds that language proficiency should be measured by what a person can do with the language in real-world tasks, not where or how they learned it, and that the ACTFL Proficiency Guidelines are the standard for doing so.

LTI advises organizations not to use their own bilingual staff to assess proficiency, because untrained assessors produce unreliable results. It recommends that employers set a required proficiency level per role through task analysis, then test prospective and current employees against it.

On automation, LTI's position is that machine scoring is a trained evaluation model, not generative AI, and that it must be validated against certified human ratings and monitored over time. Its stated top priority is "continually innovating and improving the language testing experience."

Who uses Language Testing International

  • Corporate HR and talent teams verifying bilingual hires, running bilingual pay differentials and auditing staff; clients include AT&T, Verizon, Deloitte & Touche, Liberty Mutual, Mayo Clinic, Blue Cross Blue Shield, JetBlue, Hawaiian Airlines, and Samsung.
  • Federal, state and local government : Department of Defense, Department of State, Defense Intelligence Agency, Defense Language Institute, the New York MTA, state education departments, court interpreter services and police departments.
  • Colleges and universities (more than 120 named clients) for placement, exit requirements, program evaluation, teacher certification and credit by examination, including Brigham Young, Yale, Johns Hopkins, Rice, Michigan State, Middlebury, West Point and Georgetown.
  • K-12 districts and schools using the AAPPL and ALIRA for program assessment and the Seal of Biliteracy, including Riverside County, Denver Public Schools, Knox County Schools and the New York City Department of Education.
  • Individuals : job seekers, teacher candidates, students seeking college credit, and professionals who want a verifiable credential or digital badge.
  • Not for : people who want language instruction or practice quizzes; admissions offices that accept only TOEFL or IELTS; organizations that want a free unproctored screener with no credential.

How Language Testing International works

An organization opens a free client account (no minimum volume), chooses the test and scale it needs with help from LTI's sales team, and orders tests; government buyers can order at GSA rates. State and local agencies can purchase via Sourcewell cooperative contract. Candidates take the test remotely with a webcam proctor, or on site with an authorized proctor such as an HR representative or faculty member.

Certified ACTFL raters score speaking and writing; reading and listening are auto-scored. Results post to the client site, candidates receive a certificate and an optional Credly badge, and any third party can verify the credential online for two years. Individuals follow the same flow by ordering directly at languagetesting.com.
