ESL stands for "English as a Second Language." It refers to programs and courses designed to teach English to non-native speakers. These classes help learners improve their reading, writing, speaking, and listening skills in English, which is essential for communication in many countries and workplaces. ESL programs can be found in schools, community centers, and online platforms. They cater to various age groups and proficiency levels, from beginners to advanced learners. Many ESL teachers use interactive methods and real-life scenarios to make learning engaging and effective, helping students gain confidence in their English abilities.
