This document discusses how obtaining online TESL certification can enhance your career as an English teacher. It notes that while TESL training was traditionally only available in-person, online programs now offer the same curriculum at a lower cost and with the flexibility to learn remotely. The online courses cover topics like English language teaching methods, skills, and grammar, and provide lessons and aids for teaching beginner and intermediate levels. Obtaining TESL certification online is a convenient alternative or supplement to in-person training for those without time or money for classroom courses.
