ESL classes, or English as a Second Language classes, are designed to help non-native speakers improve their English skills. These classes focus on teaching reading, writing, speaking, and listening in English, making it easier for students to communicate in everyday situations. Typically offered in schools, community centers, and online, ESL classes cater to various proficiency levels, from beginners to advanced learners. Instructors use a variety of teaching methods and materials to engage students and enhance their learning experience, helping them gain confidence in using English in both personal and professional settings.
