NATECLA recommends that all staff teaching English to speakers of other languages, whether in ESOL, Literacy or Functional English classes, should be trained as a specialist teacher of ESOL.
If you are interested in teaching ESOL, or are already doing so and would like to take a training course leading to a teaching qualification, there are several different routes you can take:
Initial ESOL teaching qualifications
Cambridge CELTA and
Trinity Cert.TESOL are initial qualifications that provide a practical introduction to ESOL teaching. Many employers prefer teachers to have these certificates even though they are not part of the English national framework of teaching qualifications.
The nationally recognised generic teaching qualifications for the Further Education and Skills sector have a variety of names: Diploma in Education and Training (DET, previously DTLLS), PGCE, PGDE and Cert Ed are all common titles. Since 2013 these qualifications have not been compulsory for teachers, but employers such as FE colleges normally require them and will probably ask you to take a generic PGCE, Cert Ed or DET to follow on from your CELTA or Cert TESOL.
Full ESOL teaching qualifications

There are also subject specialist teaching qualifications available in some places. These have been available for around 15 years but there are now fewer centres offering them. If you want to become fully qualified to teach ESOL in the Further Education and Skills sector in England, the most comprehensive option is an integrated specialist ESOL qualification or a specialist pathway in ESOL – a Diploma, Cert Ed or PGCE in ESOL. This is a general teaching qualification as well as a specialist one, available in a few universities around the country. Some providers are offering combined Literacy and ESOL teaching courses rather than ESOL alone.
Standalone specialist course
If you already have a general teaching qualification such as a PGCE, DTLLS or DET, you can take a standalone ESOL or Literacy and ESOL diploma. This course is only offered at a few centres and may also be labelled as a CPD diploma or additional diploma.
The FE Advice website has more information about all the generic and subject specialist options, and can provide lists of courses in your region of England by email:

In Wales, Scotland and Northern Ireland?
The training requirements are slightly different in Wales, Scotland and Northern Ireland, but similar types of course are available.
And what about a DELTA or Diploma in TESOL?
These qualifications are internationally recognised and follow on from the CELTA and Certificate in TESOL, for teachers with some experience. In the UK public sector they may be seen as an advantage when applying for ESOL posts, and now that the qualifications mentioned above are less commonly available, can be a good way to extend your knowledge, skills and understanding of English language teaching. The Cambridge DELTA or Trinity Diploma in TESOL are normally required if you want to get into ESOL Teacher Training, or if you are looking at leadership posts in the private sector.
