The field of teaching English has many abbreviations and acronyms! TEFL (Teaching English as a Foreign Language) and TESOL (Teaching English to Speakers of Other Languages) are often used interchangeably, although technically TESOL includes teaching both ESL and EFL (see above for clarification on these terms).
The Bridge IDELT (International Diploma in English Language Teaching) and Cambridge CELTA (Certificate in English Language Teaching to Adults) are both 4-week classroom-based TEFL/TESOL courses. Both programs prepare you for positions teaching English to speakers of other languages and are intensive, internationally recognized, and result in certification that lasts a lifetime.
The main difference between these courses is that the CELTA was developed by University of Cambridge and the IDELT was developed by Bridge. The IDELT is offered at BridgeTEFL centers, and the CELTA is offered at authorized training centers worldwide, of which Bridge in Denver is one.
The Bridge IDELT is also offered in partnership with Metropolitan State University of Denver. Upon successful completion of the program at any Bridge center, students receive a joint certificate from both MSU Denver and Bridge.
