About the Online Delta Courses

Use this page to research and apply to take the Delta course online, from wherever in the world you're based.

Building on our years of experience and expertise with University of Cambridge ESOL teacher training courses, as well as our longstanding partnerships with over 95 teacher training centres worldwide, StudyCELTA has endeavoured to create one of the most comprehensive online Delta course guides in the world.

On this page, you can find online options for all three Delta course modules, without any need to travel to take the courses. You can see where our Cambridge-accredited centres offering the online Delta are based, read about their training formats, and apply for the course online.

You can also get in touch with one of our Delta experts, who can help you plan your Delta course by distance; whether you take just one module or all three, through the same accredited centre or different centres.

This page is dedicated solely to 100% online Delta courses. It has been developed for English language teachers who cannot travel to a teacher training centre to take the course on a face-to-face basis. If you’re interested in an online-blended Delta course (where some content is taking online, and other components are taken at the accredited centre), or a completely face-to-face full or part time course, have a look at our Delta hub page for a calendar and list of centres.

What is the Cambridge Delta

What is the Delta Course?

The University of Cambridge English Language Assessment Delta (Diploma in Teaching English to Speakers of Other Languages) is the world’s most highly-regarded diploma-level teacher training course for experienced English teachers.

The aim of the Delta is to build on and deepen your pre-existing English teaching knowledge, making you a more well-rounded teacher, and furthering your career prospects. The Delta is divided into three, separate yet interlinking modules, outlined briefly below.

You can take these modules separately, all together, and in any order – however you will need all three to be Delta qualified.

Online Delta Module 1

A written exam held twice a year, focused on extending and developing candidates’ knowledge and understanding of teaching and learning English in a range of contexts. You will need to attend a Cambridge examination centre to take the exam, which is held every June and December. This could be your online course's accredited centre, or another centre closer to you. Once you apply for an online Delta course, your Delta admissions officer and tutor can help you decide on an examination centre that is convenient for you.

Online Delta Module 2

A course focused on developing awareness and expertise in the principles and professional practice of teaching English in a range of contexts. Assessed through coursework and teaching practice.

Online Delta Module 3

An extended, written assignment with two submission dates annually. The submission can be made online. This module is divided into two streams:

Extending Practice and ELT Specialism: This stream focuses on needs analysis, syllabus design, course planning and assessment.

English Language Teaching Management: This stream is based around situation analysis, planning and implementing change.

Minimum Entry Requirements

The Delta Course is intended for experienced teachers wishing to extend their professional experience and accept new responsibilities, as it not only demonstrates a commitment to the profession, but is also proof of ability.

It is open to people from all language backgrounds. All participants must have native speaker proficiency, both written and spoken, that enables them to follow the course and complete all assessed and non-assessed elements successfully.

Ideally applicants should:

  • have at least two years' full time (1,200 hours) experience of teaching English to a variety of levels within the past five years.
  • have a range of teaching experience in different contexts and at different levels.
  • be a graduate and have an initial teaching qualification (i.e. CELTA, Trinity Cert TESOL or equivalent)
  • have a standard of English which will enable you to teach at a range of levels (native-speaker proficiency, such as C2, CPE or IELTS 8+)

We may still accept applicants if they do not strictly meet these requirements but can demonstrate that they would be likely to complete the course successfully. If you're unsure about your eligibility, get in contact with one of our Delta experts, who will assess your profile and let you know if you're eligible to apply.

About the Accredited Centres

While the courses listed here are 100% online, your Delta tutor and the centre accredited the course are in a specific, physical location. You should choose which accredited centre to take the course through based on several factors, such as time zones, dates, the intensity of each course, and its structure. A further explanation about each accredited centre can be found on the individual online Delta module pages.

Online Delta Module 1 Online Delta Module 2 Online Delta Module 3

Please note that for Delta Module 1, you will need to attend a Cambridge examination centre to take the exam, which is held every June and December. This could be your online course's accredited centre, or another centre closer to you. Once you apply for an online Delta course, your Delta admissions officer and tutor can help you decide on an examination centre that is convenient for you.

You do not have to attend the accredited centre to take to online Delta course; it can be taken from anywhere in the world. 

Why take the Online Delta Course?

For English as a second language teachers, the Delta is the next professional step in their teaching career. After undertaking initial, recognised studies (such as the CELTA or Trinity CertTESOL), and teaching English for the equivalent of two years (1200 hours) full-time, a teacher can apply to take the Delta.

The Delta course can not only deepen your knowledge of the theory and practice of English language teaching, but can also further your career and open the way for more senior roles, such as director of studies, teacher trainer, author, speaker or school owner.

The online Delta course is a great option for teachers who cannot travel to an accredited centre to take the course, either because of where they are located, or because of work or other commitments. Taking the Delta course by distance can often be a much more flexible option for people who cannot dedicate large portions of their week to study face-to-face.

Regardless of whether you take the Delta completely online, online-blended or face-to-face, provided you pass at the end, the certificate you receive will be exactly the same. Your accredited centre will provide you with a provision certificate upon successful completion of the course, while the University of Cambridge Language Assessment Department sends your official certificate via post.

The Delta is designed to build on and strengthen your capabilities as an English language teacher, set you up for positions of higher responsibility, and make you a more sought-after employee for English language academies.
