Diploma in English Language Teaching to Adults (Delta)
This highly valued diploma qualification is aimed at teachers who already have substantial teaching experience and are looking for further career progression. Teachers who hold an initial qualifaction in teaching English as a second language can take the Delta after having had two years' experience teaching adults. The Delta course requires a much more substantial commitment as well: it is about 10 or 11 weeks long, and includes a final exam in addition to written assignments and in-classroom teaching. Only people quite serious about the ESL profession pursue DELTA certification.
Please note: Teaching House New York offers only the CELTA training course. The information on Other TESOL Certificates is available solely to broaden your understanding of the field of Teaching English as a Second Language.
