If you've just found nits at 7am on a school morning, this is probably the exact question running through your head. The short answer, according to both NSW Health and the NSW Department of Education, is yes - you're not required to keep your child home from school. But we don't think that means you should send them in untreated, and here's why we think that's not a good idea.

What NSW Health says

NSW Health does not recommend excluding a child from school for having head lice. According to their official guidance, a child does not need to be sent home immediately if head lice are found, and exclusion isn't required as long as treatment begins before the next day of attendance.

NSW Health's reasoning is straightforward: head lice don't transmit disease, and excluding a child doesn't actually break the cycle of head lice spreading through a school community - since at any given time, most schools already have some level of head lice present among students.

What the NSW Department of Education says

The Department of Education takes a consistent position with NSW Health. Head lice are treated as a common, non-serious occurrence - particularly in primary schools and the Department notes that anyone, regardless of age or how clean their hair is, can get them. Rather than exclusion, the Department's approach focuses on early detection and treatment at home, and many NSW public schools run a “Nitbusters” program, where parent volunteers help identify and manage head lice using a comb and conditioner.

So it's allowed - but is it a good idea?

This is where we'd push back a little: just because you can send your child to school untreated, doesn't mean you should.

Here's the practical problem: if your child goes to school with untreated head lice, they're not the only one affected. Head lice spread through direct head-to-head contact, which happens constantly at school at the reading corner, on the bus, during sport, in a group photo snd in the playground. If your child passes lice to a classmate before you've treated them, that classmate now has their own infestation to deal with, on their own timeline.

And here's the part most people don't think about: because of how the head lice lifecycle works, that classmate could easily re-infest your own child weeks later, once you've done all the hard work of treating and clearing it. You get rid of the lice, your child goes back to school lice-free, and a few weeks after that, the same lice now grown into egg-laying adults on someone else's head come straight back to your child through the same ordinary contact. It becomes a cycle that keeps circling back through the same friend group.

That's not a reason to panic, and it's certainly not a reason to feel guilty - head lice spreading through a class is genuinely nobody's fault. But it is a good reason to treat before your child heads back to school, rather than sending them in without doing anything and hoping for the best.

The bottom line

NSW Health and the Department of Education are right that exclusion isn't necessary but does increase the risk of nits spreading. But starting treatment as soon as you can before your child's next day at school protects your own family from a longer, repeating cycle, and it's a genuinely considerate thing to do for the other families in your child's class too.
