CTELL Program Overview

To meet the increasing needs of individuals seeking advanced training in teaching English as a second language, the English department at the University of Colorado Denver offers an online Graduate Certificate in Teaching English Language Learners (CTELL).

The online English language certificate program is designed to build the necessary skills to teach adults English as a second language through focused preparation. It is primarily aimed at native speakers of English who want to teach overseas, but may serve the needs of international students wanting to teach English in their home country or other countries.

Program Details

Upon successful completion of the program, CTELL participants will be able to:

  • Discuss the theoretical basis of second language instruction
  • Demonstrate a variety of effective ESL teaching techniques
  • Explain, in pedagogically relevant ways, the linguistic structures of the English language


All applicants must have a bachelor’s degree or the equivalent, with a 3.0 GPA, to be accepted to the program. Graduate students at CU Denver will also be permitted to apply for the certificate while they are concurrently completing another graduate degree. Permission may not be granted to graduate students in the applied linguistics option of the Master of Arts in English program.

Non-native speakers of English are required to submit an official TOEFL (Test of English as a Foreign Language) report showing a score of at least 580. Those who score below 580 but above 525 on the TOEFL may be admitted conditionally to the program. Under these conditions, students will have their English language skills assessed by the faculty of the program immediately after they arrive on campus to determine whether further courses are needed to develop English language proficiency. After assessment, the students may be assigned to full-time language study in an intensive English program, permitted to take graduate-level classes on a conditional basis along with further designated language study or permitted to begin graduate study without further restrictions.
