I currently teach English in the United States to immigrants and refugees seeking American citizenship. I wanted to build my English teaching skills, and also to make myself more attractive to future employers. After researching several programs, I chose UNI-PREP's 120-hour TESOL Certification in the Fall of 2019 because of the price and the flexibility of doing it online at my own pace. I was not disappointed. The course materials were clear and straightforward. I also liked the option to review quiz errors and re-take the quiz if I wanted a higher grade. I would recommend this program to anyone looking to add to their ESL resume.
