TEFL/TESOL Certificates

A TEFL certificate is recognized worldwide as an entry-level credential for teaching English as a foreign language (EFL, 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 the dominant language is not English.
  • 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.

All TEFL/TESOL Certificate classes are noncredit.

Program Details


This four-week course is offered in-person at the University of Arizona and is intended for individuals who plan to teach English professionally and in a long-term capacity. It has been designed to meet the needs of novice teachers by combining comprehensive foundational coursework in language acquisition theory, teaching methodology, classroom management, and assessment. It also incorporates a 30-hour observational and guided classroom Practicum for hands-on experience.

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. Courses include different media and require students to submit weekly assignments. Students receive a 50-hour certificate for each course and a 150-hour certificate upon completion of the three courses.

Starting October 1st

This course is offered completely online and in a self-paced basis. Trainees can start and finish the course at any time throughout the year. 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.

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. The Practicum combines classroom observations, debriefings, assistant teaching and feedback with a CESL faculty member. It is intended to provide trainees with hands-on and authentic experience in the ESL classroom and to connect previous teacher training with classroom application and implementation.
