While the shool authorities take pride in thier unconventional exercises, the children are seen going through excruciating physical pain and weeping, a news agency reported.
Quoting an eyewitness the media report said that students, mostly 10 to 14 years old, were made to walk on the beds of charcoal and glass while the parents and guardians watched as mute spectators.
The school authiorities informed that for five years now, they have been holding a two-day and one-night summer camp during which they organise river crossing and rope climbing exercises.
"We have not had any complaint so far," said one of the directors of the school, identified as Kalpesh Patel.
Out of the 126 students who took part in the events, only one girl broke down before walking over the firebed and was promptly withdrawn from it, Patel said defending the exercises.
"We give basic training in meditation and other self-confidence boosting exercises which build intrinsic strength," he added.
Meanwhile, District education officer K R Jhanjhuria has ordered a probe into the incident.
