About this exam

DELTA (Diploma in Teaching English to Speakers of Other Languages) is described by Cambridge English as an advanced blend of theory and practice aimed at experienced teachers. It is positioned as internationally recognised as the benchmark for teaching quality, and it sits at the Proficient to Expert stages on the Cambridge English Teaching Framework. The qualification is intended for English language teachers who have been teaching for at least one year, for teachers who want to progress into more senior roles such as head of English or teacher trainer, and for experienced teachers who want to extend their expertise in a specialist area. It is open to first language and non-first language speakers of English with a CEFR level of C1 or above, and it is suitable for teaching any age group, from young learners to adults. DELTA consists of three modules, which can be taken in any order or combination, so candidates can sequence the modules around their own work and study circumstances. It can be taken as a face-to-face, online, blended or distance course with an authorised centre, and centres are available across the world. Preparation therefore means choosing an authorised centre and delivery mode that fits your context, then building a study plan around the module or modules you intend to take. Candidates should confirm current module content, assessment tasks, dates and fees directly with their chosen centre, as these details are not set out in the source material used here.

What you'll study

Common questions

About DELTA Module Three preparation

Who is eligible to take DELTA?

Cambridge English states that DELTA is for English language teachers who have been teaching for at least one year, and for first language and non-first language speakers of English with a CEFR level of C1 or above. It is also aimed at teachers seeking senior roles such as head of English or teacher trainer, and at experienced teachers extending expertise in a specialist area.

Do I have to take the three modules in a fixed order?

No. The source states that DELTA consists of three modules, which can be taken in any order or combination. That flexibility lets you sequence modules around your teaching timetable, your centre's availability and your own development priorities. Confirm the practical sequencing options, timetables and any local entry requirements with your chosen authorised centre before you commit.

What delivery options are available?

DELTA can be taken as a face-to-face, online, blended or distance course. Cambridge English directs candidates to authorised centres, which are available across the world, so the modes actually offered vary by centre. Ask your shortlisted centres which modes they run, how tutor support and observed practice are handled in each mode, and what the workload looks like week by week.

Is DELTA suitable if I teach young learners or adults?

Yes. The source states that DELTA is suitable for teaching any age group, from young learners to adults. The qualification is not restricted to one teaching context, so primary, secondary, adult and other settings are all within scope. Your choice of specialist focus and your own teaching context will shape how you approach the assessed work.

How much does DELTA cost and how long does it take?

The source material used for this page does not state fees, course length, assessment dates or result timelines, so no figures are given here. These details are set by authorised centres and can differ between them and between delivery modes. Contact several centres directly and ask for a full cost breakdown, including any resit or reassessment charges, before enrolling.

How difficult is DELTA?

Cambridge English describes DELTA as an advanced blend of theory and practice and places it at the Proficient to Expert stages on the Cambridge English Teaching Framework, so it assumes substantial classroom experience rather than introducing teaching from scratch. Expect to read, write about and apply theory to your own practice. The one-year minimum teaching requirement exists because the assessed work draws on your own learners and lessons.

What should I do to prepare before starting?

Start by confirming entry requirements with an authorised centre, then audit your own practice: keep records of lessons, learner profiles and materials you may draw on. Read widely in your intended specialist area and practise writing analytically about your teaching decisions. Because modules can be taken in any order or combination, plan which module fits your current role and workload first.

What are common reasons candidates struggle?

The source does not list failure rates or common failure modes, so treat any specific claims with caution. A practical risk is underestimating the workload alongside a full teaching timetable, since DELTA is aimed at working teachers. Another is choosing a centre or delivery mode that does not suit your schedule. Discuss time commitments and support arrangements with your centre before enrolling.
