I have always taken my daughter out of school for vacations. I work for a company where your vacation selection goes by seniority & needless to say, school vacation weeks are the first to go, including summer, so if I want to vacation as a family, I have no choice. this being said, my daughter is a straight A student (7th grade) & I have always received cooperation from the teachers. She does her work & reading during the vacation & works harder when she gets back. If her grades suffered I wouldn't do it.
