Which qualification must an interpreter meet to be considered an expert witness?

To qualify as an expert witness, an interpreter must demonstrate knowledge, skill, experience, training, or education relevant to the subject matter of the testimony. This standard ensures that the interpreter is not just fluent in a language but has the necessary expertise to accurately interpret evidence or testimonies in a legal context, which is critical for maintaining the integrity of the judicial process.

While experience in legal courts, proficiency in multiple languages, or a background in psychology may contribute to an interpreter's qualifications, the core requirement is that they possess the appropriate level of expertise related to the specific interpreting tasks they will undertake in court. Therefore, the broader criterion of knowledge, skill, experience, training, or education encompasses all these aspects and establishes a clear foundation for determining whether someone can serve effectively as an expert witness.
