Teach English as a Second Language at Home or Abroad

City University of Seattle’s Graduate Certificate in Teaching English to Speakers of Other Languages (TESOL) is a dynamic, hands-on learning experience designed to bridge theory and practice. Our students gain valuable knowledge in language acquisition theories, course development and materials selection, practical classroom management, and application skills. Courses are available in online, hybrid mode, or in-class format. We offer one of the only online-certified Graduate Certificate in TESOL programs that include 10 hours of observing live English instruction.

City University of Seattle offers a unique, fast-track opportunity for students who would like to earn their graduate Teaching English to Speakers of Other Languages (TESOL) certificate and transition to teaching abroad. A TESOL certificate is a globally recognized standard that can be the key to unlocking new opportunities abroad. The TESOL program offers the flexibility you need to continue working while taking classes. You choose your own timeline for completion – our five-week, on-campus summer intensive or three quarters online/mixed mode. CityU provides the perfect place for you to see and practice what you’ve learned. Our Intensive English Language Program serves as a live laboratory for teacher candidates.  At CityU, we have a whole team ready to answer your questions and get you on the road to success.

Intern in Mexico Experience

The Intern in Mexico Experience is an option for students who are planning to start an MEd in Adult Education with a TESOL emphasis after completion of their TESOL certificate, or who wish to experience teaching abroad.In this program, students spend one quarter (11 weeks) at one of nine bilingual high schools in the beautiful city of Puebla, Mexico, where they assist English and content instructors in the classroom and act as cultural ambassadors of English. The roles and responsibilities of the intern are determined by the host high school and vary based on each school’s immediate needs. These expectations are clearly outlined before students are placed in a given school. The program is offered in partnership with Universidad Popular Autónoma del Estado de Puebla (UPAEP).

Intern in Seattle Experience

The Intern at City University of Seattle Experience is only an option for students enrolled in the MEd in Adult Education program. Students who choose CityU as their internship site work with an experienced mentor as they assist in facilitating classroom activities. City University of Seattle’s campus is conveniently located in the heart of downtown Seattle and in close proximity to our residence hall.
