The results come out, your child scores 94 in maths, and by evening every friend in the society has heard about it. You are proud of the mark, and less proud of how it is being shared.
This is a skill gap, not a character flaw. Most children who show off want something reasonable, like respect or belonging, and are going about it in a way that doesn't work.
Why does my child boast about marks to friends?
Usually, they want people to think well of them. Researchers Irene Scopelliti, George Loewenstein and Joachim Vosgerau studied self-promotion in a paper titled "You Call It 'Self-Exuberance'; I Call It 'Bragging'" (Psychological Science, 2015). They found that people who promote themselves project their own feelings onto their listeners: they overestimate how proud of them and happy for them others will feel.
The study looked at adults, but children may well fall into the same trap. Your child is thrilled about the 94, so they assume their friend will be too. The friend who got 61 may feel differently.
Home can feed this too. A study of 565 children aged 7 to 12 and their parents, followed over four waves six months apart, found that narcissism was predicted by parental overvaluation, not by a lack of warmth (Brummelman and colleagues, PNAS, 2015). Overvaluation meant parents believing their child to be more special and more entitled than others. Warmth, meaning affection and appreciation, predicted self-esteem instead. As lead author Eddie Brummelman put it in Ohio State University's release, parent training can teach parents "to express affection and appreciation toward children without telling children that they are superior to others."
So before talking to your child, check the messages at home. If the marks are announced at every family gathering, your child may be copying a pattern. We wrote separately about why you should stop discussing your child's marks with relatives.
How does bragging affect friendships?
The same 2015 study found that self-promoters underestimate how annoyed their listeners feel, and that overdoing it often backfires: listeners saw them as less likeable and as braggarts. In other words, the boast can buy the opposite of what your child wanted.
For children the cost may show up in small ways: friends stop sharing their own marks or leave your child out after results day. Your child may not connect this to the boasting, so you may need to.
What should I say to a child who shows off marks?
Pick a calm moment, not right after the incident and not in front of siblings or friends. Here is a script you can adapt:
Start with real warmth: "I'm really happy for you. You worked hard on fractions and it showed."
Get curious, not accusing: "When you told Aarav your mark, how did he look?"
Help them take the other side: "What do you think he got? How would you feel if he told everyone his mark was higher than yours?"
Name the goal behind the boast: "I think you wanted your friends to see you as good at maths. That's a fair thing to want."
Offer a better move: "Next time, wait until someone asks. Then say your mark simply, and ask how theirs went."
Avoid lines like "Nobody likes a show-off." Shame teaches a child to hide feelings from you, not to manage them.
How can we celebrate good marks without showing off?
Move the celebration inside the family, and make it about effort and learning rather than rank.
Celebrate at home: a favourite meal, a call to grandparents your child makes themselves, or a note on the fridge about what they worked on.
Praise the process: "You redid every wrong sum from the last test" says more than "You're the smartest in class."
Keep comparisons out of it: no "you beat Riya this time." If siblings are involved, see our guide on how to stop siblings fighting over who scored better.
Practise kindness in the open: ask your child who found the test hard, and whether they could help.
A child who explains a tricky problem to a friend shows their knowledge in a way friends welcome. The Fermi Problem Library has worked problems with a step-by-step solver that explains the reasoning rather than printing an answer, which makes a better thing to share than a score.
What if my child is always top of the class?
Children who often come first get more attention, which can make boasting a habit. See our guide on how to support a child who always comes first in class. If the showing off comes with anger at losing, falling out with many friends, or real distress about marks, talk to the class teacher or school counsellor, who sees your child among peers every day.
Start tonight with step 1 of the script: tell your child, warmly and specifically, what you are proud of.
