Language proficiency tests are standardized assessments designed to measure an individual's ability to use a specific language. These tests evaluate skills in areas such as reading, writing, listening, and speaking. They are often used for academic admissions, job applications, or immigration purposes, ensuring that candidates meet the required language standards. Common examples of language proficiency tests include the TOEFL for English, the DELE for Spanish, and the JLPT for Japanese. Each test has its own format and scoring system, allowing institutions and employers to gauge a person's language skills accurately and fairly.
