The ACTFL OPI is a live interview conducted telephonically between an ACTFL Certified OPI Tester and the individual whose language proficiency is being assessed. The interview lasts between 20 and 30 minutes depending on the proficiency level of the trest taker. A ratable sample is elicited through a series of personalized questions that adhere strictly to a standardized elicitation protocol designed to establish the speaker's highest level of sustained ability as well as the level at which the speaker is no longer able to sustain all the assessment criteria for the level. The elicited speech sample is digitally recorded and rated by the tester according to a standardized ACTFL OPI rating protocol. The rating assigned to the elicited speech sample reflects the descriptors contained in the ACTFL Proficiency Guidelines Speaking. Each sample is independently rated by a minimum of two ACTFL Certified OPI Testers. The two ratings must agree exactly. Any rating discrepancy is arbitrated by a third Certified OPI Tester and an Official ACTFL OPI Rating is assigned when two ratings agree exactly. The languages include: Afrikaans, Akan-Twi, Albanian, Amharic, Arabic, Armenian, Azerbaijani, Baluchi, Bengali, Bosnian, Bulgarian, Burmese, Cambodian, Cantonese, Cebuano, Chavacano, Czech, Dari, Dutch, English, French, Ga, Georgian, German, Greek, (Modern), Gujarati, Haitian Creole, Hausa, Hebrew, Hiligaynon, Hindi, Hmong-Mong, Hungarian, Igbo, Ilocano, Indonesian, Italian, Japanese, Javanese, Kashmiri, Kazakh, Kikongo-Kongo, Korean, Krio, Kurdish, Lao, Malay, Malayalam, Mandarin, Mandingo-Bambara, Nepali, Pashto, Persian-Farsi, Polish, Portuguese, Punjabi, Romanian, Russian, Serbian/Croatian, Sindhi, Sinhalese, Slovak, Somali, Spanish, Swahili, Swedish, Tagalog, Tajik, Tamil, Tausug, Telugu, Thai, Tigrinya, Turkish, Turkmen, Uighur, Urdu, Uzbek, Vietnamese, Wolof, Wu and Yoruba.
