English as a Second Language (ESL) refers to programs and courses designed to teach the English language to non-native speakers. These classes focus on improving skills in speaking, listening, reading, and writing. ESL is essential for individuals who want to communicate effectively in English-speaking environments, whether for work, study, or daily life. ESL programs are offered in various settings, including schools, community centers, and online platforms. They cater to learners of all ages and backgrounds, helping them gain confidence and proficiency in English. Mastering ESL can open up opportunities for education, employment, and social integration in English-speaking countries.
