Camping Uk

Actually I was planning to join a 30-day sports camp for my daughter. She is in the 10th grade and is going to be giving her boards in march 2009. Can anyone tell me how many holidays she will get so she can attend the camp without missing school?
actually she is in a branch of delhi public school in Punjab, India.

I need to no reasons why people are for and against wildlife parks and safari holidays. This is for school, so your help would be great.
Thanks (:
