Overview
The ACTFL Oral Proficiency Interview (OPI) is a speaking test from ACTFL, the American Council on the Teaching of Foreign Languages. It is a conversation with a trained and certified tester, designed to measure how well you speak a language without rehearsed answers. Language Testing International (LTI) schedules and runs the test on ACTFL's behalf. Schools, government agencies and employers use the result for admissions, placement, hiring and certification.
Who can take it
ACTFL's page does not set eligibility limits. Anyone who needs a speaking rating in a language can take it. ACTFL lists more than 70 languages, including Spanish, French, Mandarin, Arabic and Japanese, with some marked ILR-only; LTI says the OPI is available in 100+ languages.
Exam pattern
The interview has four parts, and it adapts to what you can do.
| Part | What happens |
|---|---|
| Introduction | The tester explains how the interview works |
| Warm-up | Relaxed conversation on familiar topics |
| Main interview | Two kinds of questions: level checks, which find the highest level you can sustain, and probes, which go one level above to find where your speech breaks down |
| Cool-down | A return to easier ground to end the interview |
Language Testing International describes the OPI as a live telephone interview of 20 to 30 minutes with an ACTFL Certified Tester. The content is adapted to your academic, professional and personal experience.
Marking and results
Ratings follow the ACTFL Proficiency Guidelines for Speaking and cover the scale from Novice through Superior. The rater looks at function (the tasks you can carry out), accuracy (how well you are understood), content and context, and text type (how much you say and how well it is organised). These are not scored separately; together they give a single global proficiency rating. After an official OPI, a digital badge showing your range is sent automatically through Credly.
How to apply
Tests are ordered through LTI. Organisations such as schools, government agencies and companies can contact LTI to set up testing.
Preparation tips
Practise unscripted conversation on work, study and personal topics.
Expect questions that check your level and then push above it.
Practise asking questions, narrating, describing and giving and supporting opinions, the kinds of task the testers look for.
ACTFL does not provide practice materials, because the test is meant to be unrehearsed, but it publishes a familiarization guide to the format.
Is it a pass or fail test?
No. The result is a proficiency rating, not a pass mark. What counts as enough depends on the school or employer asking for it.
