With Christmas coming, Santa is gonna find out who’s naughty or nice. But a UK company, School Stickers, has jumped in early and done the hard work for him.

School Stickers supplies 10,000 schools with rewards, which teachers give students for good behaviour. A lot of schools log progress online, so the company can see how many stickers each student is receiving. A bit of data analysis, and bam – we have the annual “naughty or nice” list.

So who is topping the list in 2016? Well, here are the naughtiest kids, according to School Stickers:

But don't take it to heart if your child's name is high up on the naughty list.

“Our annual ‘Santa’s Naughty and Nice list’ is just a bit of Christmas fun and not to be taken seriously," School Stickers' managing director Neil Hodges insists.

“We have been issuing this list since 2009 as it is popular with parents and teachers. Many people also find it amusing, and like to see whether their name is included. However, all schools reward differently, with some giving out hundreds and some thousands of rewards, so there is about as much accuracy to this as if Rudolf had written it.”
