What makes the Advanced Diploma different
The Advanced Diploma is for teachers who want more than an entry qualification. Alongside the core modules and advanced grammar and phonetics, it adds a research assignment, a specialism and an introduction to educational management and administration, so you can take on responsibility in a school or centre.
The research assignment
Module 10 asks you to use reference materials and complete a research assignment or project on an aspect of English language teaching. It builds the habits teachers need to keep improving: reading, reflecting and testing ideas in class.
Specialisation options
- Young Learners: teaching children and teenagers, classroom routines, positive correction and engaging activities.
- Business English: teaching adults at work, business writing and speaking, and adult classroom management.
Educational management basics
You are introduced to how language schools and departments are organised: planning courses, managing materials, supporting colleagues and administrative tasks. It is a first step towards senior teacher or coordinator roles.
Who gets most from it
- Teachers with some experience who want promotion
- New teachers who want a strong, specialised qualification from the start
- Teachers targeting competitive markets where 150+ hours stand out
Time and cost
Designed for up to nine months of self-paced study, the Advanced Diploma costs US$390, £325 or ₹27,140 including GST, with an optional fast-track add-on.
How the Advanced Diploma compares
- Versus the 150-hour Diploma: adds a research assignment, a specialism and management basics.
- Versus the 350-hour PG Diploma: the PG Diploma requires a degree and covers both specialisms in more depth.
- Versus taking courses separately: one integrated qualification and certificate.
Career outcomes
- Specialist young-learner or business English teacher
- Senior teacher in a language school
- Course coordinator for a programme or level
- A strong foundation for the PG Diploma later
No degree needed
The Advanced Diploma is open to anyone with good English, so it is a strong option for teachers without a degree who want a substantial qualification.

Entry requirements
Good English communication. No degree or teaching experience is needed to enrol, although many countries ask for a degree for teaching visas.
How you are assessed
Each module ends with multiple-choice questions, and the answer key is emailed to you so you can review your work. At this level you also complete lesson plans, projects or case studies graded by tutors, and a final assignment. The course uses Communicative Language Teaching (CLT).
Teaching practice
Teaching practice is optional but strongly recommended if you have never taught. Arrange sessions with a school or institute near you, and London College of Teachers will provide a recommendation letter for the internship.
