Oral Proficiency Interview (OPI)
The Oral Proficiency Interview is a language test that evaluates how well a person can speak a language in real-world situations. It involves a conversation with an evaluator, who asks questions to determine the speaker’s ability to use the language effectively in different contexts. The test adapts to the speaker’s skill level, ranging from basic to advanced, and provides a rating based on proficiency. In the context of missions, the OPI helps assess a missionary’s ability to communicate fluently in the local language, which is crucial for building relationships, sharing the Gospel, and engaging with local communities.
