The Delta (Diploma in Teaching English to Speakers of other Languages) is an advanced course for experienced language teachers, and a requirement for some senior English language teaching posts.

The course aims to provide a blend of theory and practice that will deepen your understanding of the English Language, enhance your teaching skills, and help you develop professionally.

The Delta is assessed by Cambridge English Language Assessment and is recognised by Ofqual at level 7 on the Qualifications and Credit Framework.

Module 2

Developing Professional Practice


Module 3

Option 1: Extending Practice and ELT Specialism
