Delta – The Alternatives

The Pond.

In the world of ELT qualifications, the Cambridge Delta often takes the spotlight and it can be quite difficult to hear about any other diploma-level qualifications unless you go looking. This post aims to give you a brief overview of some of the other diploma-level qualifications available to English teachers, what the differences are and how to get more information. Firstly, we will look at the two ‘big fish’, Delta and DipTESOL, and then look at some other lesser-known ‘fish’.

The Big Fish – Delta vs. DipTESOL

Cambridge Delta.

If you’re reading my blog, then you probably know that I’ve completed Delta. And, you probably know that I have very positive feelings towards it. You can read more here if you like. That being said, I thought I would give a short summary of Delta here just so you can compare with the later options.


  • Number of modules: 3
  • Time: Usually takes between 1.5 – 2.5 years – some integrated programmes are completed in 9 months (can also be done on an intensive course – 3 months)
  • Price: Depends, however you are generally looking at about €3000 +
  • Qualification level: 7 (60 credits)
  • More information: The Cambridge Delta website.
  • Useful blogs:
    • Sandy Millin’s blog.
    • Lizzie Pinard’s blog.
    • DELTA course blog.

Trinity DipTESOL

The Trinity DipTESOL is perhaps the most well-known diploma-level qualification after the Cambridge Delta. Whereas the Delta is split into three modules, the DipTESOL is split into four. Something which really interests me about this course is Module 3 – Phonological theory in classroom practice. Phonology is something which I love, however am still not as confident as I want to be (even after taking Delta). Perhaps this is a reason to choose the DipTESOL over Delta? Perhaps not. It is certainly something that I would like to do in the future after I have completed my MA in TESOL. Here is an overview of the modules taken from the Trinity DipTESOL information leaflet.

  • Number of modules: 4
  • Time: Generally 1 year (can be done on an intensive course – 3 months)
  • Price: Around €2600
  • Qualification level: 7 (60 credits)
  • More information: Trinity DipTESOL website.

The Other Fish.

LTi Diploma in TESOL

This is a relatively new Diploma and it is delivered mainly in Asia and Australia. The Diploma can be taken fully online, from what I gather, and seems to cover everything that the diploma should cover. Here is an overview of the course content:

  • Number of units: 14 units (from what I can see)
  • Time: About 2.5 years
  • Price: About $3000 (Aussie dollars)
  • More information: The LTi website

Note: David Robertson from LTi has just informed me that they now operate in Tokyo and Osaka. More information can be found here.

INTESOL 390-Hour Diploma with Teaching Practice

INTESOL is a company that has been around since 1993 and provides a range of different training courses. The diploma that they have advertised covers all the expected content over 17 modules. There is the option to choose the diploma without teaching practice as well, although I’m not sure why you would do that. Looking around for reviews on the actual diploma course, I haven’t been able to find any. What’s more is that the school is accredited by ALAP, which is an independent accreditation organisation – not OFQUAL. That being said, the price is a lot cheaper than other diploma-level courses. I’ll see if I can dig deeper and find out more!


  • Number of modules: 17
  • Time: Doesn’t say, however the title of the diploma states that it will take about 390 hours to complete. I imagine about a year or so.
  • Price: £1000
  • More information: The INTESOL Diploma website.

The London Teacher Training College OFQUAL-regulated Diploma in TESOL

This teacher training centre, much the same as INTESOL, has been around for about 30 years but hasn’t really broken into the market in terms of reputation. Well, at least I had never heard of it. That being said, they offer an OFQUAL-regulated Diploma which consists of 4 modules. Interestingly, they also offer other diplomas:

It makes me wonder about the differences between the different Diplomas advertised. Of course, OFQUAL is the official government accreditation body of the UK, so at least you can be reasonably sure that the course is up to scratch. Here is an overview of the course content:

  • Number of modules: 4
  • Time: 372 hours – So I’m guessing about a year or more.
  • Price: £1200
  • Qualification level: 6 (36 credits) – So this is where this course differs from Delta and DipTESOL
  • More information: LTTC website.

Final notes.

Within this great pond of ELT, there is a lot of BS. So, when choosing your provider for any course, not just diploma-level courses, choose carefully. You’re investing a lot of time AND money, so you need to be sure that at the end of that course you will have gained usable and up-to-date knowledge and a certificate that is recognised by employers. My advice is to do your research, speak to the providers, look at their accreditation and try to read some reviews from past candidates.

If you are reading this and work for or have studied with any of the mentioned providers and feel like telling me about your experience, please get in touch via the contact page. I’d love to hear your thoughts and will most definitely share them on this blog (with your permission of course).

Thanks for reading!



  1. Hi Jim,
    Thanks for posting about the LTi Diploma of TESOl I offer.
    I have training centres in Bangkok, Manila, and Tokyo.
    By the way, the Diploma of TESOL takes 90 weeks part time.
    Enjoy your day,
    David Robertson
