The school offers students a wide range of club activities appropriate to their age. Joining a club is one of the many ways in which we will seek to encourage students to pursue areas of personal interest.

The Nature Club aims at inculcating an appreciation of nature among students and encouraging them to participate in a variety of conservation initiatives. Its efforts include inviting leading environmentalists to the school to talk to students and sensitize them to the opportunities and challenges in addressing environmental issues, organizing an annual tree-planting day, and participating in important nature-oriented programmes.

In 2006, Dhirubhai Ambani International School received affiliation to The Hague International Model United Nations (THIMUN) which marks a significant achievement for us, being the only school from India and the whole of South Asia to achieve this honor. In January 2008 a delegation of 22 students from our school participated in the prestigious 40th annual THIMUN (The Hague Model United Nations) conference held at The Hague, Netherlands, which focused on the theme of climate change. Our students have also participated in the SPIMUN (Saint Petersburg International Model United Nations).

The Dhirubhai Ambani International School Model United Nations (DAIMUN) is a forum for students where they have an opportunity to simulate the United Nations. Its conferences are conducted as a formal debate along the lines of UN procedures generally concerning a topic with global implications -- humanitarian, political or social. A valuable platform that tests students' skills of diplomacy, confidence and knowledge, it inspires young minds with the spirit of inquiry and understanding. DAIMUN plays a key role in fostering students' leadership potential and commitment to civic engagement. The DAIMUN Conferences are completely student-run and is in keeping with the purpose of education at Dhirubhai Ambani International School - to develop character, courage, confidence and self-esteem in students apart from providing them with a sound basis in academics.

Our class 9 students participated in the THIMUN Conference held at Singapore in 2008 and the class 11 students attended the one held at The Hague in 2009.

'Paigaam', a peace conference organized by our students, seeks to build harmonious relationships through the exchange of ideas and fact-based debate in the spirit of openness and mutual response.
