TOEFL

 The Test of English as a Foreign Language or TOEFL, evaluates the ability of an individual to use and understand English in an academic setting. It was developed to address the problem on ensuring English language proficiency for non-native speakers wishing to study at American universities. It has become an admission requirement for non-native English speakers at many English-speaking colleges and universities. Additionally, institutions such as government agencies, licensing bodies, businesses, or scholarship programs may require this test. A TOEFL score is valid for two years and then will no longer be officially reported since a candidate's language proficiency could have significantly changed since the date of the test. Colleges and universities usually consider only the most recent TOEFL score.
 Policies governing the TOEFL program are formulated with advice from a 16-member board. Board members are affiliated with undergraduate and graduate schools, 2-year institutions and public or private agencies with an interest in international education. Other members are specialists in the field of English as a foreign or second language. The TOEFL Committee of Examiners is composed of 12 specialists in linguistics, language testing, teaching or research. Its main responsibility is to advise on TOEFL test content. The committee helps ensure the test is a valid measure of English language proficiency reflecting current trends and methodologies.

 To apply for exchange student program, I would need to get a good score of TOEFL. I'm planning to apply for the program after I get discharged from the army, so I will start preparing for this after that.
