TDIIS has been classified into four parallel Clans named after the four universal elements of Air, Fire, Earth and Water. We constantly endeavor to implant our learners with the attributes of these four significant elements. These clans help the students in understanding the homogeneous nature of Indian society and clan system. Students from different classes unite together to form groups and compete for scholastic, co-curricular and other personality developmental activities. Inter houses activities also prepare the students for inter-school and state level activities.
