I just thought I'd throw in my opinion/thoughts on this entire thread. There is no particular order of importance to my replies. I'm soooo sorry for the length of this post. I cut as much as I felt I could.
I'm sure some districts have stricter laws than the state laws. I'm in Texas which says you must be in attendance 80 days of the semester. That means if the semester is 82 days, you may miss 2 days that semster without having to justify your reasons (personal reasons qualifies as excused when written by parent); if there is 108 days that semester you could miss 28 days. Most semesters in our district are 88-93 days; it varies from semester to semester, year to year. If you don't like the public school policies, you do have other options: Charter schools (I'm interested in knowing the charter e-school one poster uses), private schools of all types, home schooling, even moving (not too viable for most people, but still an option).
Teachers are waaayyyyyy over worked and underpaid. I do not begrudge any teacher for taking some personal time. Kids need to learn to adapt, so I don't see the harm in a sub for a day or two, or even five. I know many teachers (no I do not teach nor does anyone in my family) who have to work during the summer just to make ends meet. Vacationing during all that "off" time isn't an option.
Most of a child's educational experience doesn't take place in the classroom. Study after study shows that the basics in life and learning take place between birth and age 6. Around here, about 50% of kids don't even start kindergarten until 6. Did you know the #1 thing to predict a boys rate of success in college is if their dad read to them at least 20 minutes a day from 6 months to age 4? So, I can't really see the harm of missing 3 days of a 40 minute biology class as a freshman. Life skills and experiences will take a child much farther in life than disecting a rat. Even if they are going to be a doctor, I'd feel much better about their experiences in medical school than in high school at 14, especially since the person teaching them doesn't have any extra ordinary skills. Doctors teach medical school.
Classes are over crowded in most public schools. Even good schools. With 30 kids in a class, there isn't a lot of one on one time and it causes the class to move fairly slowly. Teachers can't accomadate a fast learner when they have to make sure the slowest student is getting it. And slow and fast has nothing to do with overall intelligence and class placement. Certain concepts are just easier to pick up for some kids than others, and it can vary in subject to subject. For example, by 16 months DS#1 knew all his letter sounds (thanks to the ABC songs by Seasame Street I played as music in the car), but he still didn't recognize all his letters. The "harder" skill was much easier for him than the "easier" skill. Once he did learn all those letters at 3 1/2, reading came exteremly quickly (days). You couldn't stop him if you wanted to. Anyhow, my point is when you pull a child out and help them at home, essentially homeschooling them for the days they miss, they can spend a lot less time getting the concepts down.
And personally, I feel homework is just busy work 50% of the time. Yes, it is there to re-enforce concepts and to help those learn that haven't mastered a concept. But for those who have already "gotten it", it's just a waiste of time. That's why in college, you don't hand it in. And writing out a word 15 times, never did make me a better speller (as you can probably tell). Either I knew it by the first time, or I never did learn it. Don't get me wrong, if homework is assigned, homework is to be done. Just like a job. And when missing school, I think homework is important; that it does make up for the time lost in class. I also feel that when homework is given (and done) in advance it is a good thing. Then the teacher can grade it when grading all the other same papers, not adding to their work load.
My parents pulled us out for vacations all the time. In addition, we did miss when we were sick and my mother was never beyond taking us out just to spend a little time with us doing something purely fun. I graduated high school (a very competive school) with a 3.6. I discoverd in college I need to attended class OR do the homework. Some classes I did 50-50 (English classes for example), some classes I attended without fail (communication type courses), other classes I only showed up on test day (math!). I graduated college with a 3.8 gpa. Maybe it was missing all that school pre-college that set me up for success. Maybe it is just the way I'm wired. One of my sisters grades never were the greatest (C/D), but they pulled her out too. There never was a difference in her grades between semesters when she was in attendance every single day and when she missed. However, the individual assignments when she missed were usually better than when she attend. Food for thought.
While a lot of jobs are based on attendance, not every job is. Many jobs don't care about your "hourly" rate. You get paid to do a job. That may mean some 60 hour work weeks and other weeks were you you can get it done in 20 hours. Many, many jobs require that you can work on your own and not have to be "babysat". Another skill learned by not being forced to attend school without fail. How many people do you know that had their parents watch their every move through high school that went wild in college and didn't amount to much afterwards? We've all had the shock at our 20 year high school reunions where the successful kid didn't have a successful life. Kids need to learn to function outside the box.
OK, so as you gather from my exteremly long post (if you've even read it all), I'm not against pulling kids out of school. I don't think it hurts them. In many ways, I think it can be helpful. Their is no subsitute for life experience. Family time is of the utmost importance. Mandatory attendance is all about money. The government admits as much. And I don't see anything wrong with that either. I do believe that kids should attend school (both for the education and social value). School is very important. From the time my kids are born they are being encouraged (age appropriately) to go to graduate school and to do well. But when the school doesn't allow me to make the best choices for my kids, I look to my other options I first mentioned.
I just feel as though a different solution needs to be found to balance the needs and desires of both the parents and the schools. I'm a big supporter of year round school, when done right. But that is all a different post and this is long (too long) enough.
