The OPI Tester asks open-ended questions along the ACTFL Scale of Proficiency from Novice Low to Superior. The OPI is an adaptive test where question level difficulty is adjusted based on the test taker's responses.
The test is similar to a conversation, but a standard interview protocol backs every test element. The recorded speech samples are human rated by ACTFL-certified OPI Raters.

Available in commonly tested languages, the OPIc is a 20–40-minute speaking test conducted via the internet using a computer with a headset and microphone.
