CELTA stands for Certificate in Teaching English to Speakers of Other Languages.
You may notice the acronym doesn’t match up! That’s because it used to stand for Certificate in English Language Teaching to Adults.
It is the singly most internationally recognised qualification requirement for anyone looking to start a career teaching English as a foreign language – or TEFL as the industry is better known. Almost all legitimate language schools around the world require their teachers to hold a CELTA (or full equivalent such as Trinity TESOL.)
The CELTA certificate is officially a Level 5 qualification, meaning it is directly equivalent to a Foundation degree or HND, making the CELTA one level below a Bachelor’s or Honours degree.
The Cambridge CELTA replaced the CTEFLA in 1996, which in turn replaced the RSA in 1985.
