And parents who booked holidays oblivious to controlled assessments which teachers might be able to rearrange unlike exams. One teacher has posted before to say she was spending part of the school holidays helping those children catch up. Another poster said something along the lines of 'sod that let them fail' but it's not so easy when pay, promotion and even job security depend on getting them all through.
And that's where the old system of asking for permission worked so much better... Permission would never have been granted when there were controlled assessments. It could have prevented this problem entirely.
But I have to say in 19 years of teaching, over 5 institutions in three different counties, I have never had 5/6 or even 3/4 children off school at any one time due to holidays. I really don't think this is the norm.
If anything, most children tend to go in the summer when the bulk of the teaching has been done and everyone's on wind down, or at then end of terms when you tend not to be teaching crucial information anyway (I as do many other teachers tend to have that planned in as contingency time, so you can go back over anything not quite covered, or they didn't understand the first time etc...)
These problems that you speak of, just doesn't correspond to my experiences over the past 19 years, and I'm guessing Jelly's, or many of my teacher friends either.
Tell me Tiggy, have you ever taught yourself... Is this from your experience of problems, or just your projection of them?
