IIMS is affiliated to the Indian Montessori Association (IMA)
IMA is a registered society founded by Shri Rajendra Gupta, Smt. Radha Nagaraj and a few like-minded Montessorians, to propagate the ideals and principles of Montessori method across different stages of development, from infancy to primary. The Association began its work by working closely with IIMS in ensuring quality control in training, particularly for those who want to work in the Primary. Now, it has added on the job of supporting research within the Montessori set up as well as bringing in research from outside the group to the community.
IMA also acts an umbrella to bring together all stakeholders who are interested in the cause of the child, whether they are working Montessorians, School management, parents or others. It uses this network to communicate both within the Montessori community and to a wider group of non-Montessori Institutions and public.
