I dont know about reporting you to the authorities, but starting 6 years ago, at the junior-senior high school level our school system switched to a block schedule ( the kids go to 4 90 min classes each day) so that each class meets 2-3 times each week or 5 times every 2 weeks. At that point if a student missed 10 days or more in the entire school year for any reason at all, points would be taken off their grades, lowering their gpa. More points for each additional day missed. There are absolutely no excused absences (college interviews, surgery, death in the family, vacation, etc) so unless you can guarantee that your child will never break a leg, get the flu, have a grandparent die, etc no one is willing to use 5 days or more on a vacation. I know Mass takes every holiday in the book, & we get both a Feb & April vacation week, so once my daughter reached 7th grade we only took wdw trips during April vacation. However, we did take 3 October trips when she was in elementary school & had no problems with her keeping up with her work.
