BLINDLY following rules that have no basis in any kind of common sense is not something I've taught dd - and frankly I'm finding myself edging towards godwits law in how I feel about such an approach.
Rules that ensure the safety of pupils and GENUINELY encourage learning (and don't even get me started on the fact that schools in U.K. Are becoming further and further away from learning as opposed to indoctrination!) are fine - particularly if regulated SENSIBLY!
THIS is utterly ridiculous and really does have some distinctly nasty tones of racism about it!
I also get the very distinct impression especially from some of the earlier posters that they haven't even looked at the actual haircut under question.
It is as pps and myself have said actually quite a standard fairly conservative styling that really wouldn't look amiss in the majority of office settings.
If ANYONE is causing an UNNECESSARY distraction from learning for this pupil or indeed others it's the school - not the pupil or the mother!
Maybe uk pupils would be achieving better if schools and by default teachers (I know teachers don't always agree with the rules either but are required to enforce them) ACTUALLY concentrated on education rather than petty discriminatory rules.
