@britey, i think it only happens to Catholic Schools run by Priests or Nuns. Back home i studied in a Catholic School that have a very strict rules.if the student is suspected pregnant or they got pregnant out-of-wedlock, they are not permitted to continue their studies or if not expelled from the school.

Delhi School has it's own rules and policies, so i think the parents should be happy with it. (At least they will know if their daughter/s is pregnant or not :) isn't it?)
