Teacher cuts pupil's hair, mum files police report

If you had read the thread you'd have seen that it was actually a requirement of this national exam (which is oral), that children are not allowed to take it unless they conform to the dress/appearance code.

Whatever can be said about his getting warning letters and such prior to this incident, I think it is a dumb rule to bar students from exams just because their hair is long

And looking at your post above, no, I really don't think it's oppressive or no reason to live in Singapore or anything like that (I in fact think it's a pretty cool country). Rather, I think it is completely not cool to bar students from taking national exams for such a rule being broken because he can always get his hair cut afterwards while I seriously doubt that they would let him take the exam later.
