Delta: advance your English language teaching career

The Delta (Diploma in Teaching English to Speakers of Other Languages) is the highest qualification available for English language teachers.

The Delta is an advanced blend of theory and practice that will deepen your knowledge and understanding of English language teaching.

Delta is awarded by Cambridge English, part of the University of Cambridge.

Why study for your Delta? 

To progress your English language career and take your teaching to the top. A Delta sets you apart as an advanced teacher. It shows you are dedicated to both your students’ learning and your own.

With a Delta you can step up to senior positions and new opportunities, including becoming a Teacher Trainer, Director of Studies or Head of Department. You can also write English language teaching textbooks and become a published author.

A Delta-qualified teacher can also travel all over the world using their new skills on specialist projects within a range of schools, including training other teachers.

How does a Delta work? 3 steps to become an advanced teacher 

To be Delta-qualified you need to complete 3 Delta modules:

Delta Module 1: Understanding language, methodology and resources for teaching 

Module 1 focuses on extending and developing candidates’ knowledge and understanding of teaching and learning English in a range of contexts.

Topics include:

  • Different teaching approaches and methodologies
  • Language systems and learners’ linguistic problems
  • Knowledge of resources, materials and reference sources for language learning

Assessment: written exam

Delta Module 2: Developing professional practice 

Module 2 focuses on developing awareness and expertise in the principles and professional practice of teaching English in a range of contexts.

Topic include:

  • The language learner and the language learning context
  • Evaluating, selecting and using resources and materials for teaching purposes
  • Observe and evaluate other teachers’ lessons

Assessment: portfolio of coursework, including background essays, observed lessons and a professional development assignment.

Delta Module 3: Extending Practice and ELT Specialism 

Module 3 focusses on needs analysis, syllabus design, course planning and assessment. You will carry out an independent investigation, leading to the design of a course programme related to a specialism.

Some of the specialisms include:

  • Business English
  • Teaching Young Learners
  • English for Specific Purposes
  • Teaching English to learners with special requirements

Assessment: written assignment

This is an advanced course, so you will need to already have your CELTA (alternative qualifications may be considered) and have a minimum of two years’ teaching experience.
