TEFL/TESOL Certificates

A TEFL/TESOL certificate is recognized worldwide as an entry-level credential for teaching English as a foreign language (EFL; this is also known as TESOL, which means Teaching English to Speakers of Other Languages). A TEFL/TESOL Certificate prepares people without prior education degrees or teaching experience how to teach English in the foreign language classroom.

A TEFL/TESOL certificate is the right choice for you if:

  • You are interested in becoming an English teacher in a country where English is not the dominant language;
  • You are a professional in a related field who is considering transitioning into the profession of language teaching;
  • You are a language teacher who wants to complete coursework for professional development purposes.

CESL offers face-to-face and online courses that range from 100 to 150 hours of training. Please visit our three different TEFL/TESOL Certificate options to determine which one better meets your time availability, learning preferences and interests. You should also research the countries where you would like to teach in order to learn about the minimum number of hours of training and/or classroom experience requirements.

⇒ All TEFL/TESOL Certificate courses are noncredit and, therefore, do not count towards an undergraduate or graduate degree. A TEFL/TESOL Certificate does not allow you to teach in the U.S. unless you have another qualifying degree.

⇒ CESL also provides notarization and authentication services that are required for work visa processing, as well as job placement assistance for certain countries.

This certificate consists of three 50-hour, eight-week online courses. Each course is led by a CESL faculty member and includes six modules each. Students are required to complete weekly discussion postings, quizzes and assignments, and receive constant feedback from their instructor. Students receive a 50-hour certificate for each course and can request a 150-hour certificate upon completion of the three courses.


This course is offered completely online and on a self-paced basis. Students can start and finish the course at any time throughout the year, and are not required to interact with an instructor or meet any weekly deadlines. This course is suitable for those who need to complete their TEFL/TESOL Certificate in a short period of time or by a specific date. This course follows the same curriculum as the 150-hour Online TEFL/TESOL Certificate.

The 20- or 40-hour Practicum can be added to any of CESL’s TEFL/TESOL Certificate programs or taken alone as an independent component by those who already have a TEFL/TESOL Certificate. The Practicum combines classroom observations, assistant teaching and feedback from a CESL faculty member. It is intended to provide students with hands-on and authentic experience in the ESL classroom while applying previously acquired teacher training theoretical and practical knowledge.
