Foreign language proficiency refers to the ability to understand, speak, read, and write in a language other than one's native tongue. This skill can vary from basic conversational ability to advanced fluency, depending on the individual's experience and practice. Proficiency is often assessed through standardized tests, which measure various aspects of language use, including grammar, vocabulary, and pronunciation. Achieving foreign language proficiency can enhance communication with speakers of that language and open up opportunities in education, travel, and employment. Many people pursue proficiency in languages such as Spanish, Mandarin, or French for personal or professional reasons, contributing to cultural exchange and understanding.
