IRS follows the syllabus prescribed by the NCERT at lower classes and the State Board in the higher classes. The teachers carefully analyze the syllabus and provide supplementary lessons wherever required. The subjects taught from Class I to II are English, I Language and Mathematics. For Classes III to V, Environmental Studies is also taught. The activity-based methodology we follow in primary level makes the learning fun and easy for the students. It also facilitates quick learning and helps students understand the basic concepts clearly.

The subjects covered in the High School are English, Hindi, regional language, Physical Sciences, Biology and Mathematics. After the teaching classes the students are given opportunity to explore the subjects further themselves in the library period. The books available at the school library are well utilized by the students and the information gathered is discussed in the classroom in the presence of the teacher.

Parallel to the school library, we have ‘Books-on–Line’; a system that gives an opportunity to the students to read books in the class itself during the recess. To detail, a limited number of books is hung on a wire in the classroom which the students have access to in their leisure time. The computer lab is open for the students from Class I. IRS students learn more by doing. The higher-class students take up projects in computers and in different subjects.
