The administration of the test is the responsibility of the Educational Testing Service (ETS). It is a computer-based assessment designed to evaluate English language proficiency in four main areas: Reading, Listening, Speaking, and Writing. Many universities and institutions worldwide use TOEFL scores as part of their admission requirements. Each section is scored on a scale of 0 to 30, and the total score can range from 0 to 120, reflecting the test-taker's overall English proficiency. TOEFL scores are frequently necessary for university admissions, visa applications, and professional certifications, particularly in English-speaking countries. Scores are valid for two years, and test-takers have the option to retake the exam as many times as necessary.
