Delta, or the Diploma in Teaching English to Speakers of Other Languages, is a post-experience, in-service teaching qualification, the aims of which are to enhance your professional knowledge and expertise and sharpen your practical teaching skills.

The most highly regarded and widely recognised qualification for experienced English language teachers, it is awarded by Cambridge English Language Assessment (formerly Cambridge ESOL), which is part of Cambridge University, and is ‘a widely recognised qualification which helps you build better teaching practice and can lead to greater rewards and enhanced career opportunities’ (Cambridge ESOL, The Delta Modules, 27/07/09).

Delta comprises THREE modules. Each module is independently assessed and separately certificated. You need to complete each module successfully to be awarded the Delta diploma.

Module 1 focuses on the background to teaching, the theory that underpins it,  practical applications and how these are informed by linguistics and language learning theories. It is assessed by a two-paper written examination.

Delta Module 1 focuses on the background to teaching, the theory that underpins it, practical applications and how these are informed by applied linguistics and language learning theories. It is assessed through a two-paper written examination. This 12-week course will focus on the key areas you need to develop in order to pass the Delta Module 1 examination.

The course consists of 12 weeks of online tuition, followed by a further week of online revision. In addition to the required background reading, you will need to complete various online tasks, several longer assignments, and some exam practice tasks.You should expect to be doing around 15-20 hours’ study per week.


Module 2 aims to develop your professional practice. It concentrates on your teaching and is assessed through a portfolio of observed lessons, background written assignments and an externally assessed lesson.

This is a programme designed by you and your personal tutor. The course is intensive and requires full commitment.

As part of Delta Module 2, you will need to complete 5 assignments (essay + lesson) and a diagnostic lesson. It is important that you complete the tasks and assignments on time. Given the background work around each lesson, it is important that you space out lessons sensibly, so that you can devote enough time to each of them. This also allows you time for reflection and further development. You will need to put together a work plan at the beginning of the course.

Depending on your teaching situation you have the option of taking the course over 16 weeks or 36 weeks. 

Face-to-face lessons are required for your assignments, but if you currently don’t have face-to-face classes due to Covid-19, you are able to start the Delta M2 programme focusing on the written tasks and teach your lessons later on in the course.

Module 3 focuses on a specialist area of your choice (e.g. English for Specific Purposes; teaching a group from a particular cultural-linguistic background) and is assessed through an extended written assignment.
