Christmas is coming and Santa is checking his list twice to find out who’s been naughty or nice. According to School Stickers, a UK-based provider of rewards in schools, a child’s name can be a determining factor in whether he or she is naughty or well-behaved.

They’ve been conducting the study annually for the past 11 years, based on the records of 27,000 primary school students across Britain.

Neil Hodges, managing director at School Stickers, said the research is not intended to be taken seriously, but is “just a bit of festive fun”.

“Our much-loved ‘naughty and nice’ list has become a Christmas tradition,” she continued, adding that “People do seem to like to see each year whether their name has made the list.”

For further clarification, Neil said, “School Stickers is trusted by thousands of schools to reward pupils for good behavior and achievement. We’re proud that our rewards, whether they are stickers, postcards, badges or certificates, motivate and inspire young people, whatever their names.”

So, did your name make the cut (for either good or bad) this year? Check out the lists below to find out:

Some of the naughty names, such as Jacob, Jamie, Joseph, Liam, Luke, Michael, Owen, Eleanor Holly and Olivia, have previously made appearances on the naughty list in past years.

While names like Sophie and Daniel have both made the top ten nice names for the past six years out 11 years.

Emily, Grace, Jessica, Benjamin, Harry, Jack, James, Oliver, and Thomas, have been in the top ten nice names list five times.

While these lists change over the year, with new names cycling in and out of being naughty or nice, they could still give soon-to-be parents inspiration for naming their upcoming babies.

And if your name does happen to be on the naughty list, you better prepare for your lump of coal this year.
