Lauded by the Wall Street Journal as “one of the better known programs in the country,” The Boston Language Institute is the oldest and most innovative TEFL/TESL certification school in Boston. The Institute offers 11 intensive English teacher training certificate programs (4 weeks) and 3 part-time programs (12 Saturdays) per year. Since its inception, the program has featured foreign students of English for practice teaching, a phenomenon we pioneered in Boston. In 2002, we also pioneered the first dedicated TEFL Certificate Program for non-native speakers of English.


Since 1981, the Institute has successfully taught over 160 foreign languages and English as a Second Language (ESL) in our elegant, feng shui designed facilities in Boston’s centrally located Kenmore Square. We also teach on-site in the area’s corporations, schools and well-known universities, always stressing authentic and effective communication. In developing our TEFL/TESL Certificate curriculum, we have drawn on more than 3 decades of experience to provide a lively, interactive program that will train you to create the dynamic lessons that have won our programs such renown.


Since its inception in the spring of 2000, the TEFL/TESL Certificate Program has trained just over 1900 teachers. Our graduates teach in the United States and over 30 countries around the globe -- China, Japan, Korea, Colombia, Mexico, Brazil, Costa Rica, Spain and Morocco, to name a few. Many have shared with us the extent to which the program has prepared them for their EFL and ESL careers. Many of our graduates have taught foreign languages and ESL at the Institute; some have become TEFL trainers and program coordinators. While this site is intended to give a sense of our program and answer your questions, we invite you to visit us in person or to join us at one of our monthly Open Houses. We invite you also to schedule a morning observing the program and speaking with our staff to experience the unmatched program quality and client service for which we are so well known. Please contact Elizabeth Mbaya, program coordinator and program graduate, at or by phone at 617-262-3500 x244. We look forward to the pleasure of meeting you.


Full-time programs begin monthly.

Part-time Saturday programs begin September, January and April.

Instruction offers students an opportunity to work one-on-one with an instructor at their own pace. The instructor carefully selects materials and plans lessons to effectively meet the student's goals and individual learning style.

Private programs offer a flexible schedule and a customized curriculum. A minimum of 24 hours of instruction with one or two classes (each 90 or 120 minutes) per week is the suggested module, but dates, times and content can be arranged according to your requirement.


Core programs(popularly known as Group Classes) are offered in classes of 4 to 12 students year-round in popular languages. In an effort to better suit our clients’ schedules and language learning goals, classes are offered in a client friendly format of 6-week sessions (4-week accelerated sessionsin summer). This format allows students to:

  • continue from one session to the next with no more than a 2-week break.
  • begin any level in any session.
  • progress more rapidly through 4-week summer Fast-Track programs.
  • benefit from a more efficient and student friendly class schedule.


Immersion programs are designed to teach the equivalent of levels 1 to 5 of the Institute's regular core programs in one 6-week or 4-week, 90-hour sessions. Classes meet Monday through Friday, 3 hours a day in 6-week programs/4.5 hours a day in 4-week programs.

The main goal of these programs, which meet in small classes of 4 to 12, is to help students, from day one, to increase confidence in their ability to use their new language in a wide range of real-life situations and improve their oral skills as they progress from level to level.
