Master of Science in Teaching, TESOL

Designed for people who hold an undergraduate degree but are now considering teaching as a career, the MST Teaching English to Speakers of Other Languages (TESOL), All Grades, program at St. Thomas Aquinas College may be your gateway to enhancing your career.  

According to the National Center for Education Statistics, there is a nationwide shortage of teachers prepared to support students for whom English is not their first language. In New York State, 10% of the public school population alone were labeled English Learners in the academic year 2021-2022 (New York State Education Department), and the need for new and well prepared ENL teachers is expected to grow.

The MST-TESOL at St. Thomas Aquinas College prepares recent graduates, teaching assistants, and career changers to teach all students whose first language is a language other than English. 

This 36 credit graduate program provides candidates with the foundational knowledge and content pedagogy to meet the needs of English language learners in all grades. MST-TESOL candidates will also complete a minimum of 70 days of supervised Student Teaching experience in an English as a Second Language (ESL) classroom that will allow them to work with diverse learners.
