“After six and a half years working as an occasional elementary school teacher and seeing no light at the end of the tunnel, I decided to enroll in the ACE TESOL Diploma program at the Peel District School Board.  The program grabbed my attention because it was full time and during the day.  I wanted to be in and out quick.  It was intense but worth it.  I completed the course in June and the practicum in October.  After completing the program, I did feel I had a pretty good handle on creating lessons and working with people from diverse backgrounds; I was ready to jump into a classroom.  I began applying for ESL jobs and sent my resumes to school boards even if they weren’t hiring.  I ended up getting an interview with a school board.  Three weeks later I got the job!  It was a casual position, which made me hesitant at first, but I knew it was my only way in.  Then in 8 months I got a permanent part-time teaching position and two months later, a full-time position.  I was ecstatic!”

The Practicum

Practicums are conducted in real adult English language classes. The 30-hour practicum is divided into 20 hours of classroom observation and 10 hours of practice teaching. For the 10 hours of practice teaching, students are assigned to a mentor teacher.

Continuing Education Units

Language education professionals can earn CEUs for completing The ACE TESOL Diploma. The international standard for CEUs is one CEU for every 10 hours of professional development, therefore participants can earn 18 CEUs for successfully completing the course with the 30-hr practicum. Please note that this is a general guideline and CEU standards may vary from one teaching context to the next. It is your responsibility to check the CEU requirements for your specific teaching context.
