I would prefer the inset days to be in the holidays for children, or always at the end or beginning of term, so working parents could plan childcare properly, and teachers should of course be paid for them. It is hard to plan for a day in the middle of term for many.
So, is the reason they are in term time, because the government made these training days compulsory, but refused to pay teachers extra? So it was a choice between closing the school, or working 5 extra unpaid days? If the INSET days are in the school term as it was before INSET was introduced (ie INSET has reduced number of days for children, but teachers work the same amount of days), surely teachers are being currently paid for them? Or have I misunderstood?
Ok, let's see if I can answer that for you. Start with the idea of putting them all next to holidays, because that makes sense for childcare etc as you say. Schools can do this sometimes, because they have someone on the staff who can organise some of the training or they are doing something which doesn't need an outside trainer. Or they got lucky and managed to get a trainer in on a date next to a holiday.
But, say they really need training on a particular subject, they find a trainer, but he's not available on the date they want, he can only manage a mid-term date. Suddenly you have a choice between not getting this essential training, or having an INSeT day mid-term. So your child is off on a random Wednesday which isn't ideal but isn't necessarily in the school's control.
However, having dictated that teachers needed these opportunities for training (the government made the training days compulsory as you stated above) it was also dictated that the children should not lose 5 days of their education. So instead, teachers lost five days of their holiday. A mid-term INSeT is added on to their education at the end of term instead (they might now break up on the Thursday instead of the Wednesday of the final week of term). So they do the same number of days of learning as they ever did. And, just to make life more fun, the government also refused to pay extra. So teachers, compared to before the days were introduced, work unpaid on five holiday days, or have five days less holiday for the same pay, or however you want to look at it. It isn't a reduced number of days for children.
