Again, I say...it is the parent's call ... not the teachers or the schools. I, too, am a teacher - and have been in 3 states... my hubby has been one (is now in private business), in three states - and my mom an elementary teacher. We cover the spectrum from K-post-secondary.
I am in no way advocating for parents to take kids out of school but it depends on the child, the state, and the school. Private is different than state schools. State schools are different than charter schools and home schooling is different than all the above.
As a parent, I do what is best for my child. It will be different for each child and each parent. Each child is unique in their ability to learn and interact as well as handle stress, etc. Just as each family situation is unique.
If the amount of time my child was missing from school ever became an issue...I would choose to do home schooling ... and then it wouldn't be an issue. That is me ... wouldn't be my first choice but is always an option.
And, I agree, if parents do not take the time to work with children who miss school (for whatever reason) it is a lot of extra work for teachers. So, as a parent you need to take responsibilty for your child and put in the extra time, effort, and money (for tutors) that is necessary to bring your child up to speed. And, if you don't feel your child will be successful if they miss the days...then don't take them out of school.
Again, the parents should have the final say. Of course, that isn't to say that all this shouldn't be done in cooperation with the teacher, school and school district. All of which are important.
Yes, school is important. A lot of stuff happens. But, I still believe..and forever will...that family is the most important. That being said, I think that there is a happy middle in all this...but that is different for each family.
If you have to take kids out of school or decide to that ... be responsible ... do the "homework" to find out the consequences and implications ... and then do what it takes to make sure your child is able to fit back in.
