Isha Home School is a residential school in South India, on a thirty acre campus surrounded by forest. It teaches the ICSE syllabus, which is the Indian national curriculum examined by CISCE and taught entirely in English. Pupils sit their ICSE examinations at the end of Class 10, at about sixteen, so it lines up closely with GCSE.
What makes it different is not the syllabus. It is a deliberately gadget-free school: no personal phones, no tablets, shared computers for work only. Most of the teachers are volunteers who left other careers to teach, so the classes are taught by people who chose to be in the room. The school describes its aim as the natural blossoming of children rather than the gathering of information, and in practice that means a lot of music, art, sport and time outdoors alongside the academic work.
Pupils meet people from every walk of life, from farmers and craftspeople to people running national organisations. It is a boarding school, so the children cook, clean, resolve their own arguments and look after younger ones.
