My child Mr. Pavan krishna reddy, who is studying in 4th grade in ( ICE ) international center for excellence, malleshpalya, Bangalore. we discussed that the small behavioral issues he had with previous school like lack of concentration, sometimes doing potty at school. INITIALLY, the correspondent told he will give teacher for every 4 students and one attender for the 4 children. so we paid a hefty fees to school to a tune of 2.5 lacs /annual. my child have done potty in school 10-12 times in the 7 months, and they called for PTM every month and they discussed the issued. now, i.e, yesturday (i.e. on 14th nov 17) he did potty at school, and the asked to remove his pants in front of all teachers, and he refused to so. so they called pavan mother and told her that , he is been suspended from school and we do not need to send the child to school. i, Mr. Praveen, called the principal, for confirmation with the principal and she confirmed the same( the conversation has been recorded for further action he needed). 1) legal suggestion required to save my child future, 2) does my money has been wasted. 3) does school can punish a grade 4th child. 4) does schools have right to give TC for 4th grade child and in middle of the academic. 5) does school do not have responsible to take care of one student of the class( he is only child in grade 4th) 6) does the schools are only academics and not to correct the behavioral issues, ethical issues, social responsibility. we need to take this issues to court of law, to secure this type harassment and the pain to parents and children and their future,
