Computer-Adaptive Language Test
Exam term
A computer-delivered language assessment that selects later items partly in response to the candidate's earlier performance.
A structured interview assessment that elicits a sample of spontaneous speaking and rates how effectively a person uses a language in real-life functions. A deeper explanation shows how OPI fits into speaking assessment and proficiency, including the distinctions that prevent common confusion.

— Oral Proficiency Interview
In depth
A structured interview assessment that elicits a sample of spontaneous speaking and rates how effectively a person uses a language in real-life functions. The fuller explanation connects OPI with speaking assessment and proficiency and shows how the assessment term functions in practice.
The interviewer asks and adapts questions to find what the candidate can sustain and where performance begins to break down. The resulting speech sample is rated against defined proficiency criteria.
Key points
An oral proficiency interview resembles a conversation but follows a standardized purpose and procedure. The interviewer establishes a comfortable sample, explores functions and contexts at the candidate's apparent level, probes more demanding language, and returns to a level the candidate can sustain. Personalized prompts encourage unrehearsed speech while maintaining a common rating construct.
The goal is functional speaking ability rather than knowledge of facts about the language. Raters consider which communicative tasks the speaker accomplishes, the contexts and content handled, text type, comprehensibility, and the effects of vocabulary, grammar, pronunciation, fluency, pragmatic competence, and sociolinguistic control. A polished memorized monologue cannot substitute for sustained spontaneous interaction. Official programs also define tester qualifications, recording, rating, quality assurance, and permitted uses of results.
Examples
Common misconceptions
Certification context
A reliable understanding of OPI helps readers interpret language-test criteria, proficiency frameworks and assessment feedback with greater precision. The certification context connects the term with speaking assessment and proficiency while avoiding assumptions about a particular provider, exam or credential.
Why it matters
An adaptive interview can obtain rich evidence about spontaneous functional speaking that fixed selected-response questions cannot capture.
In certification contexts
OPI-style results are used in academic, professional, and governmental contexts, and candidates benefit from understanding adaptive probing and criterion-based rating.
