ACTFL and CEFR overlap, but do not align officially
ACTFL and the Council of Europe built independent proficiency frameworks. The conversion below is the widely cited mapping used by US universities, defense schools, and seal of biliteracy programs. Treat it as a useful approximation, not as official equivalence.
Find your OPI rating
OPI ratings are awarded on the ACTFL Proficiency Scale: Novice (Low / Mid / High), Intermediate (Low / Mid / High), Advanced (Low / Mid / High), Superior, Distinguished. Eleven sub-levels from bottom to top.
Read the closest CEFR level
The mapping is not 1:1: ACTFL Advanced spans a wide band that covers CEFR B2 and reaches into C1; CEFR C1 corresponds most closely to ACTFL Superior. Use the per-rating blurb below for nuance.
Caveat: the mapping is informal
Neither ACTFL nor the Council of Europe publishes an official conversion. Several published comparisons exist (Tschirner 2005, Buck et al. 2014, ACTFL's own informal alignment notes). Always present the OPI rating itself as the primary credential, with CEFR as the secondary reference.
OPI and CEFR: two different proficiency philosophies
Two definitions before reading any conversion.
OPI: a US-standard oral interview by ACTFL
The ACTFL Oral Proficiency Interview is a 15 to 30 minute one-to-one phone or video interview with a certified ACTFL tester, available in 120+ languages. The session is recorded and rated by a second ACTFL-certified rater on the ACTFL Proficiency Scale (Novice Low through Distinguished). Used by the US State Department, FBI, Department of Defense, Peace Corps, and 45+ states for the Seal of Biliteracy.
For European tests aligned to CEFR, see the DELE to CEFR Converter (Spanish) or other LingUp converters.
CEFR: the European reference scale
The Common European Framework of Reference for Languages (Council of Europe, 2001) defines six proficiency levels (A1 to C2) used across all European languages. CEFR uses can-do statements organised by skill (Listening, Reading, Spoken Interaction, Spoken Production, Writing). It is the standard reference for European universities, the Schengen long-stay visa process, and EU institutions.
If you have a separate Spanish certification, see the SIELE to CEFR Converter.
ACTFL OPI rating to CEFR (informal)
Widely cited informal mapping (per ACTFL alignment notes and published comparisons). The OPI itself remains the primary credential; CEFR is the cross-reference.
| OPI Rating | CEFR (informal) | CEFR Band | What this typically unlocks |
|---|---|---|---|
| Distinguished | C2 | Proficient User | Top diplomatic / academic / interpretation roles, near-native expectations |
| Superior | C1 | Proficient User | US Foreign Service generalist threshold, university faculty in target language |
| Advanced High | B2 / C1 | Independent / Proficient | US graduate language programs, military linguist roles, professional translation entry |
| Advanced Mid | B2 | Independent User | US Seal of Biliteracy gold; most European university undergraduate admission |
| Advanced Low | B2 (entry) | Independent User | US Seal of Biliteracy silver; many K-12 dual-language exit standards |
| Intermediate High | B1 | Independent User | US ROTC commissioning floor for some languages, basic professional contexts |
| Intermediate Mid | B1 (lower) | Independent User | Workplace conversational threshold, foundation programs |
| Intermediate Low | A2 (upper) | Basic User | Basic transactional fluency, tourism, short professional exchanges |
| Novice High | A2 | Basic User | Memorised phrases plus short original sentences, very limited topics |
| Novice Mid | A1 | Basic User | Single words and memorised utterances, no real conversation |
| Novice Low | <A1 | Below A1 | Few isolated words, below CEFR certification floor |
Mapping is not officially endorsed by ACTFL or the Council of Europe. Useful as a guide for cross-referencing US and European credentials; always present the OPI rating as the primary number.
When OPI is the right credential vs when CEFR is required
OPI is the dominant US credential for spoken proficiency; CEFR is the dominant European reference. Pick the right credential for the receiving institution.
The State Department (Foreign Service Institute), FBI, and Department of Defense use the ACTFL OPI directly (or the related ILR scale). Superior and Distinguished are the standard hiring thresholds for full-language-use positions. CEFR is rarely referenced.
Adopted by 45+ US states, the Seal of Biliteracy uses ACTFL ratings directly. Tiers vary by state, but Intermediate Mid is a typical floor and Advanced Low / Mid is a common gold tier.
US graduate language programs, ROTC commissioning, and credit-by-exam typically require OPI Advanced Low or higher (rough CEFR B2). OPI is the explicit credential; CEFR is rarely accepted as a substitute.
European universities expect CEFR-aligned credentials (DELE, DELF / DALF, Goethe, etc.). An OPI rating mapped to the CEFR equivalent is sometimes accepted as supporting evidence, but a CEFR-aligned test is usually required for formal admission.
Some Schengen residence-permit pathways (Spain, France, Germany) require a CEFR-aligned certificate from the official national test body. OPI ratings are typically not on the official accepted list, even at the equivalent CEFR level.
Multinational employers hiring for multilingual roles in the Americas, EMEA, and APAC typically accept OPI ratings directly, especially for less-commonly-taught languages where no CEFR-aligned test exists.
OPI to CEFR questions, answered
How do I convert my ACTFL OPI rating to a CEFR level?
There is no official ACTFL-CEFR mapping; both organisations publish guidelines but neither endorses a one-to-one conversion. The widely cited informal mapping is: Distinguished = C2; Superior = C1; Advanced High = upper B2 (sometimes C1); Advanced Mid = B2; Advanced Low = entry B2; Intermediate High = B1; Intermediate Mid = lower B1; Intermediate Low = upper A2; Novice High = A2; Novice Mid = A1; Novice Low = below A1. Use the conversion as a guide, not as official equivalence.
What is the OPI?
The OPI (Oral Proficiency Interview) is a standardised one-to-one spoken assessment developed by ACTFL (American Council on the Teaching of Foreign Languages). A certified ACTFL tester conducts a 15 to 30 minute interview, by phone or video, in the target language, eliciting speech across topics designed to probe the candidate's proficiency ceiling. The session is recorded and rated by a second certified ACTFL rater on the ACTFL Proficiency Scale (Novice through Distinguished).
Which languages does the OPI cover?
OPI is available in over 120 languages, including all major world languages (Spanish, French, German, Mandarin, Arabic, Russian, Japanese, Portuguese), many less-commonly-taught languages, and indigenous languages. This wide language coverage is a key differentiator vs CEFR-aligned tests, which tend to be language-specific (DELE for Spanish, DELF / DALF for French, Goethe / TestDaF for German). For uncommon languages, OPI is often the only standardised oral proficiency credential available.
Who uses OPI ratings?
OPI is the de facto US standard for spoken language proficiency. Major users include the US Department of State (Foreign Service Institute), the FBI, the Department of Defense (DLPT supplement and ILR-aligned roles), the Peace Corps, US universities (especially graduate language programs and ROTC commissioning), K-12 dual language and seal of biliteracy programs (45+ US states), and global corporations hiring multilingual staff. Outside the US, OPI is used by Canadian, Australian, and selected European employers.
Is OPI an oral-only test?
Yes. OPI assesses Speaking only. ACTFL offers separate companion tests for Listening (LPT), Reading (RPT), and Writing (WPT) using parallel rating scales (Novice through Distinguished / Superior). Many institutions require the OPI plus one or more companion tests to certify all four skills, mirroring the four-section structure of CEFR-aligned tests like SIELE or IELTS.
How long is an OPI rating valid?
Most US government and corporate uses treat OPI ratings as valid for 2 years from the test date. K-12 seal of biliteracy programs and university credit-by-exam typically accept ratings indefinitely once awarded. The 2-year limit reflects the assumption that oral proficiency can drift without active use; for permanent records (academic transcripts, seal of biliteracy on a high school diploma), the rating stays on the document for life.
Why is the ACTFL-CEFR mapping informal?
ACTFL and the Council of Europe (CEFR) developed independently with different philosophies. ACTFL is built around functional task descriptors (what the speaker can DO, e.g., narrate in past tense, handle a complication) and uses a 5-major-level scale (Novice, Intermediate, Advanced, Superior, Distinguished). CEFR is built around can-do statements per skill and uses 6 levels (A1 to C2). The scales overlap conceptually but do not align cleanly; ACTFL Advanced spans a wider band than CEFR B2, and CEFR C1 is narrower than ACTFL Superior. Conversion tables are useful approximations only.
How does OPI compare to OPIc?
OPI is the live human-administered interview (15 to 30 minutes with a certified tester). OPIc is the computer-administered version: candidates respond to recorded prompts via webcam and microphone in 30 to 40 minutes. Both use the same ACTFL Proficiency Scale and produce equivalent ratings. OPIc is faster to schedule and often cheaper; OPI is preferred for the highest-stakes ratings (Superior and Distinguished) where a live interviewer can probe the proficiency ceiling more flexibly.
