At MIS we believe that curriculum is not limited to books and the students have to be exposed to different activities that bring out their hidden talents through different activities. Co-curricular activities include declamations, English and Hindi debates, Singing- solo and group, art and dance competition, spelling and quiz competitions etc. all students are provided ample opportunities to harness their talent and area of interests through these co-curricular activities.

A co-curriculum coordinator coordinates all these activities and prizes are accumulated by each house. To ensure all round growth, students are encouraged to participate in these competitions. These activities takes place throughout the year except during the period of examinations.

For senior students, a fire camp is held during the festival holidays. During this activity, all senior students plan and prepare the food, fun activities as well as prepare invitation card to invite eminent guests for this function.

A bi-monthly newsletter is published that highlights the events performed and the results of the co-curricular activities are published in this newsletter. Students are encouraged to write articles for the newsletter that range from poems, stories, informative, paintings, science, languages etc. A copy of this newsletter is handed over to the parents during the Parents Teachers Meeting (PTM). A copy is also sent by post to each parent of the hostellers.
