A Master’s program is great exposure to the many theories that underpin modern language teaching methodology. Having a master’s Degree can open doors at higher education institutions such as Community Colleges and universities. However, the vast majority (about 95%) of ESL teachers currently teaching adults in private institutions only have a TESOL Certificate. There is a very good reason for this. After finishing a TESOL Certificate course, you will be armed with the practical skills and knowledge necessary to immediately step in front of a class and start to teach English. After finishing a Master’s program, you will know all about the theory behind the methodology, but you won’t have the practical skills to actually teach. Many people who complete a Master’s Degree then take the TESOL certificate so that they gain the skills they need to feel comfortable to teach their students. In a word, the TESOL Certificate program is extremely practical.
