TEFL stands for "Teaching English as a Foreign Language." It refers to the practice of teaching English to non-native speakers in countries where English is not the primary language. TEFL teachers help students improve their English skills for various purposes, such as travel, work, or education. To become a TEFL teacher, individuals often complete a certification course that covers teaching methods, lesson planning, and classroom management. Many teachers find opportunities in countries around the world, allowing them to experience different cultures while helping students learn English.
