Who are ESL Students?

ESL is taught in many countries for many different reasons. These are some of the most common reasons that people choose to study ESL.

• Business people in many countries study ESL. There is no single professional group or job that requires people to learn English. Adult ESL students might be accountants, automotive engineers, quality control specialists, buyers or merchandisers. Often someone's employer may require them to learn English. This varies based on the needs of the situation. Many companies operate in more than one country and often there is need for communication between offices. Often these ESL students are learning English not to communicate with native speakers but with people for whom English is also a second language. In other cases the employee may not be required to study English but may work for a company that offers incentives such as a higher pay grade or the possibility of promotion for those who can prove English proficiency.
• High school and College students who are planning to study abroad may choose to study ESL. Many ESL students are preparing for tests such as the GRE, the TOEFL or the IELTS. ESL students taking the GRE or TOEFL tests are generally interested in study in America. Students studying for the IELTS may be interested in any English speaking country. There are two versions of the IELTS. The first version is for general immigration. The second is for academics.
• Children in many countries are often ESL students. Many parents believe that learning English will improve their children's opportunities in life. Because of this there are many public schools including middle schools, primary schools and kindergartens that offer ESL classes for their students.
• Non-native speakers who are already living in a country where English is a dominant or official language often will take ESL classes.
• People who are interested in or enjoy learning a second language. While this group is likely the smallest there are some people who study English for no other reason than they enjoy it.
