"What I meant is that the parents who do this are most probably those who don't much value education and are therefore unlikely to have much in the way of educational attainments themselves"
Totally disagree.
I am extremely concerned about education, levels and knowledge and where my kids are against the national expectations.
it depends what your kids do when you are on holiday. If you are sitting on a beach, then fair enough its not educational. But if you are travelling around cities, different countries, even around England, your children can learn so much, and this is general knowledge which is just as beneficial.
I do wish people would stop guilt tripping other parents into not taking a holiday.
Yes, their attendance record is affected, and yes, its wrong to allow your children to continually miss school. But if they miss 2 weeks in a year its not a major hassle.
What is obvious from the Mumsnet forum is, if you take your child out of school, is dont harrass the teacher to give you work to allow your child to catch up. Its your decision to take your child out, not give grief to the teacher.
