DELTA (Diploma in teaching English to speakers of other languages) is a detailed and comprehensive course that covers advanced theory and practice to help you develop in your teaching career.
DELTA is a qualification from Cambridge English Assessment, which is part of the University of Cambridge.

You need at least one year’s experience to make the most of it, although many people take it after a number of year’s experience in the classroom. If you are planning to progress into academic management a DELTA is a very good idea. In some schools it will be a prerequisite.
There are three modules, which you can take in any order.
DELTA Module 2
DELTA Module 2 is “Developing Professional Practice”. It is assessed with a portfolio of coursework and assessed lesson observations. Topics covered are:
- The learner and learning context
- Preparing to teach
- Using resources and materials in the classroom
- Managing and supporting learning
- Evaluating lesson planning
- Observing lessons
- Professional development
The other modules
Module 1 is “Understanding Language, Methodology and Resources for Teaching”. This is the examined module, and is primarily theoretical.
Module 3 is independent research on either an ELT specialism or management. It is assessed by a written dissertation.

About the school
Do you want an online professional development course, no matter where you are in the world?
The IH Online Teacher Training Institute (OTTI) is the teacher training wing of International House World Organisation. We provide online professional development courses for EFL teachers around the world. We have courses for every stage of a teacher’s career, from soon after your initial qualification to DELTA level and management courses.
Learning online gives you the flexibility to set your own study hours and save money on travel and accommodation.
On our courses you can ‘attend’ whenever (and wherever!) is convenient for you. You don’t usually have to attend a live chat or webinar at a specific time, although sometimes there are live “meetups” so you have the chance to chat with your tutor and other classmates.
To help you there is ongoing support from your tutors in online forums and through individual feedback – and you’ll probably find your other course participants are really helpful as well. You are definitely not studying alone, and this tutor and peer support is what our trainees say they like most about our courses.

Learning online gives you the flexibility to set your own study hours and save money on travel and accommodation.
You can ‘attend’ whenever (and wherever!) is convenient for you. On our courses the material for each module is made available at the start of each module (usually at the weekend) and it is up to you to access the material and complete the tasks. Therefore, there is some self-discipline required. The more you put into the course in terms of your time spent researching, completing tasks, and taking part in the discussion forums, the more you will get out of it. You will of course have support from other course participants and your tutors in online forums and through individual feedback.
Most of our courses are asynchronous, but we also have some courses which are a mix of synchronous and asynchronous learning. These have a weekly live webinar and then a set of tasks to be done over a week.
