The International Diploma in Montessori is a comprehensive programme that is designed to equip participants with diverse Montessori teaching strategies, methods, and ideologies, that will help them become compassionate and competent educators. The 1 year certificate and 6 months upgrade to diploma course is taken on-campus at Oak House Training College. It focuses on both theoretical as well as practical knowledge of Montessori to develop teachers of the highest quality that will make a significant contribution to the lives of young children. 

Maria Montessori developed this method of teaching over 100 years ago which is still being practiced worldwide. The course consists of 8 modules and assignments. Students are given a first hand feel of how practical classes are to be conducted with demonstrations. The theory classes are conducted with in-class presentations.

The Montessori method gives children the freedom to explore and develop to their full potential within the Montessori prepared environment. It teaches practical life skills to help the child become more independent. Children learn using their senses, as their senses are heightened up to the age of six, thereby enabling the child to learn and heighten the sense in question. It also teaches, science, history and geography. 

The International Diploma is a recognized award that allows students to teach in pre-schools worldwide.
