English as a Second Language (ESL) refers to programs and courses designed to teach the English language to non-native speakers. These programs help learners improve their reading, writing, speaking, and listening skills in English, which is essential for communication in many countries and workplaces. ESL classes are often tailored to different proficiency levels, from beginners to advanced learners. They can be found in various settings, including schools, community centers, and online platforms. The goal of ESL education is to enable students to use English effectively in everyday situations, academic environments, and professional contexts.
