TOEFL

Test Of English As Foreign Language(TOEFL) is a standardized language test used to check the proficiency of non-native speakers who wish to enroll in English-speaking countries. TOEFL is accepted in more than 11,000 universities. Students will get two categories to choose from, one is a paper-based test(PBT) and the other is an internet-based test(IBT). It has four modules like any other language proficiency test and the student is measured in each module. TOEFL has two years of validity which means once you have completed your test successfully it will be valid for only two years. 

Each section has a 0-30 score range which means overall 0-120 each skill has 4 or 5 proficiency levels, so where your score lies within that range will determine your proficiency and skill.
