What is the DELTA Certificate?

About the DELTA

If you love life as an English language teacher, have been teaching at a range of levels for at least a year and are looking to progress in your career, the DELTA would be just right for you.

The DELTA is a higher English language teaching qualification for experienced teachers, who either want to move into more senior teaching or directorial roles, or hone their skills as a teacher. It is also a key step in become a teacher trainer (e.g. a CELTA tutor). The DELTA approximates to a Master’s level in terms of content.

Who is eligible?

So, who exactly is eligible for the DELTA? The criteria for taking the DELTA are that you:

  • Have some formal, certificated ELT training (e.g. a CELTA)
  • Have an equivalent of 1 year of full-time English teaching experience (i.e. 1,200 hours) in the last 5 years
  • Have a level of English good enough to teach at a range of levels – you should have an equivalent English level of high C1 on the CEFR.
  • Have a range of teaching experience involving work in different teaching contexts
  • Have experience of teaching learners at different language levels and ages.

If you match these criteria, you are eligible to take the DELTA.

You could be accepted onto a DELTA course without an existing teaching qualification (e.g. CELTA) if you are able to show that you would be likely to successfully complete a course. You could demonstrate this via successful previous examples of study.

What is the DELTA?

The DELTA comprises three different modules, which collectively make the qualification. You can take the three different modules in any order and can gain the certificates for the three different modules. Remember however, you will only achieve the final certificate after you have successfully completed all three.

The majority of people who take the DELTA will end up successfully becoming DELTA qualified, with a ‘Pass’ grade. Those who perform particularly well, will receive a ‘Pass with Merit’ grade, while those who excel will receive the highest grade; the ‘Pass with Distinction’. Please remember, it is also possible to receive a ‘Fail’ grade for the CELTA is your work doesn’t match the minimum standard required.

There is no time limit for the taking the DELTA, meaning you can take the three modules at your convenience and to suit your needs and commitments.
The 100% online DELTA modules will lead to exactly the same qualification as taking the Delta face-to-face course. The face-to-face and online options are there for you to decide the best option for you.


Many people ask about the exam or submission dates for the three different DELTA modules. There are no deadlines for the DELTA Module Two activities as there are no exams or submissions, and assessment is based on your performance as a teacher throughout the course. Module One and Module Three do have important dates for you to remember. Delta Module One will be evaluated through an exam, while Module 3 will be evaluated through coursework submission.
