A couple of thoughts upon reading this thread, probably guaranteed to cause someone, somewhere, to flame me about something. Some points from the other side of the coin (a teacher with 24 years of experience, this particular year being longer than most!)
Money - schools are paid for your child's attendance. However, this really isn't affected by your child's daily attendance unless your child is absent during FTE week. This is the week the children are counted and the money is doled out. If your child is not in school at least one day during FTE week, your school will get NO money for your child for that entire school year. Forgive them if they are a little touchy around FTE week.
Teachers and vacations - I get 6 personal days a year. I do not have to account to anyone for those days. Yes, I sometimes use them to go to Disney World. I even took a whole week off for my honeymoon this year. (gasp!) However, when I am gone, I leave detailed lesson plans, a qualified substitute teaches the class, and your child's education continues. DO YOU LEAVE A SUBSTITUTE FOR YOUR CHILD WHEN YOU GO ON VACATION? (and no - writing a lovely journal does not cover the work that was missed in school -I'm talking about the actual skills that were missed, not the lovely learning experience in Epcot's countries)
Teachers and making up work - It's not just your child who misses my class. There are lots of vacations, there are custody issues, there are doctors appointments, "things that HAVE to be done today!", cousins visiting, grandparents visiting, new pets, younger siblings who need babysitters, parents who just don't get up in the morning to get the kids to school, parents who pull their kid out early because they don't want to wait in the parent pick-up line at the end of the day, it was too cold (this is Florida, for goodness sake, how cold can it get?) it was too warm, it was too rainy, it was too windy, it was too nice (had to take the boat out) . . . . . get the picture? It is my job to teach your children during regular school hours. It is NOT my job to plan individual lesson plans based on each child's schedule, and then find time before and after school to catch every child up. I am a good teacher, I work hard at what I do, but this is my JOB, it is not my LIFE. I get to have one of those things too, you know.
State testing - No, teaching for testing is NOT good practice, it's not even close to adequate practice. But we now have this thing called "No Child Left Behind". In our state we also have this thing called FCAT, and while most of you think elementary school isn't as critical as the upper grades, guess again. Here it is, plain and simple: you fail the FCAT test in third grade you do NOT go on to fourth grade. You are absent during the FCAT test in third grade, you do NOT go on to fourth grade. It doesn't matter if you get straight A's, it doesn't matter if you're gifted, you don't get to try again later - YOU FAIL - plain and simple. Missing out on the presentation of some basic skills because you were pulled out of school for two weeks, could have serious consequences now.
Okay - while I'm sure you may not agree with what I've written, please at least think about it. Taking a child out of school isn't as simple as many of you make it sound. I'm not telling you to stop, I'm just saying perhaps the school or teacher does have some legitimate concerns and are not just trying to make your life or your child's miserable by saying "NO" to your vacation.
