The Cambridge International Diploma for Teachers and Trainers is for everyone who needs to be competent in carrying out learning and development activities professionally and productively.

The Diploma provides clear up-to-date and valued performance standards. In today's world of flexible and lifelong learning, teaching can take place in many different ways. However the skills, knowledge and understanding involved in teaching are generic and transferable. The Diploma enables candidates to work in contexts which are most relevant to them, while addressing these generic performance standards. Thus the Diploma is accessible to teacher/trainers in all areas and all levels of education and training.

The Diploma is intended for teacher/trainers in educational establishments, training organisations and companies. They can be full-time or part-time. Their teaching role may be their only responsibility or one of a number of responsibilities they have within their institution. The Diploma has been designed to be flexible, so that candidates from a variety of teaching environments have equal opportunity to demonstrate their skills, knowledge and understanding. These environments can range across teaching subject (from general to technical and vocational programmes), phase (from primary to higher education, or from basic to advanced training) and age of learners (from children to adults).
