What Exam Stress Really Does to Your Child: The Long-Term Wellbeing Risk Parents Need to Know About

New research confirms that exam stress at 15 is linked to depression and self-harm into adulthood. A positive psychology coach working with independent school families explains what to watch for — and what actually helps.

There is a particular kind of stress that builds quietly. It does not announce itself. It does not arrive all at once. It accumulates — in a shortened temper at dinner, in the stomach ache that appears every Sunday evening, in the child who used to love reading and now says she hates everything about school.

Parents of children in independent schools often tell me some version of this story. Their child was fine. Then Common Entrance crept closer, or mock GCSEs arrived, or a university offer began to feel uncertain — and something shifted. The child they know began to disappear behind a version of themselves that is anxious, brittle, or simply switched off.

What many parents don't realise is that this is not just a difficult patch. New research published in The Lancet Child and Adolescent Health in early 2026 has confirmed something that those of us working with young people have observed for years: pressure to achieve at school at age 15 is linked to depressive symptoms and risk of self-harm, and the association appears to persist into adulthood.

That is not a reason to panic. It is a reason to pay attention — and to act early.

What Exam Stress in Children at Independent School Actually Looks Like

One of the reasons exam stress is so often underestimated is that it rarely looks the way we expect it to. We imagine a child crying over their revision. What we more often see is something subtler and more confusing.

In my coaching work with young people at independent schools, I see a consistent set of patterns. Some children internalise the pressure entirely — they want to be the best, they want to make their parents proud, they want to earn their place at the school their family has invested in. When they fall short of the standard they have set for themselves, the response is not always tears. It is often a creeping loss of confidence that is hard to name and harder to reverse.

The physical signs tend to come first. Stomach aches that have no medical explanation. Difficulty sleeping, particularly on the nights before school. A loss of appetite, or the opposite — eating for comfort in a way that feels compulsive. These are the body's signals that the nervous system is under sustained pressure, and they deserve to be taken seriously.

Then come the relational signs. Falling out with friends over small things. Rudeness to parents that feels disproportionate to the trigger. A short temper with teachers. Withdrawal from the family in the evenings. These are not character flaws. They are the overflow of a child who is carrying more than they have the resources to manage.

And then — and this is the pattern that concerns me most — comes the disconnection. The child decides, quietly and without announcement, that they are not going to reach the grades they need. And so they stop trying. It is a protective move: if you don't try, you can't fail. But of course it creates exactly the outcome they feared. The self-fulfilling prophecy of academic disengagement is one of the most heartbreaking things I witness in this work, because the child is often far more capable than they believe — and far more trapped than they appear.

Where the Pressure Comes From

The UCL research, which tracked over 4,700 young people across multiple years, found that young people reported whether they worry a lot about getting their schoolwork done, whether they feel a lot of pressure from home to do well in school, and the importance of achieving at least five GCSEs. UCL The pressure, in other words, is rarely singular. It comes from multiple directions at once.

In independent schools, the pressure landscape has some specific features. Many families have made significant financial commitments — reserving places, paying deposits, funding tutors — and children are aware of this, even when parents do their best to shield them from it. The stakes of Common Entrance, in particular, carry a weight that is partly financial and partly social. The school your child goes to matters in this world — and everyone in it knows it.

There is also the pressure that comes from the school environment itself, where high achievement is the norm and comparison is constant. And then there is the internal pressure — the child who sets the bar higher than any parent or teacher has — whose perfectionism is partly admirable and partly a source of significant suffering.

None of this means that high expectations are wrong. A certain amount of pressure, the research acknowledges, can be motivating. The question is whether the pressure has tipped past the point at which it motivates and into the territory where it harms.

Why This Matters Beyond the Exam Room

The researchers found strong evidence that academic pressure at age 15 is linked to higher depressive symptoms at age 16, and the association persists for multiple years. Study participants who experienced high levels of academic pressure when they were 15 continued to report more depressive symptoms at each time point up to age 22. UCL

Read that again. Not just in the exam period. Not just for a difficult term. For years.

This is the part of the conversation that parents rarely hear, because the focus is so often on the immediate: the grade, the school place, the result. But the research is telling us something more important than any single exam outcome. It is telling us that how a young person learns to relate to pressure — to failure, to expectation, to their own sense of worth — during adolescence shapes how they will relate to it for the rest of their life.

The good news in this is significant. Because the patterns that create vulnerability are learnable — which means they are also changeable. The young person who has internalised a fixed mindset about their own ability, who has learned to manage anxiety by avoidance, who has begun to base their self-worth entirely on their academic performance — these are not fixed states. They are patterns. And patterns respond to the right kind of intervention.

What Positive Psychology Coaching Does Differently

Coaching is not tutoring. It does not help your child revise more effectively or understand a tricky concept. What it does is work on the inner architecture that determines whether any amount of tutoring, revision, or good teaching will actually land.

In our sessions with young people, we begin by slowing things down. Many anxious children have never had the experience of sitting with a trusted adult and simply being asked: what is actually going on for you right now? Not what grade did you get. Not what do you need to revise. But what is actually going on.

From there, the work is genuinely collaborative. We explore what the pressure feels like in the body — because young people who can identify and name a physical stress response are far better equipped to manage it. We work with character strengths, identifying what your child is genuinely good at beyond the academic — because a young person who knows their strengths has a resource to draw on when everything else feels uncertain. We develop practical tools: breathing techniques, thought-challenging exercises, ways of reframing the narrative around exams that are neither dismissive of their importance nor enslaved to them.

And we work, gently, on the relationship between effort and outcome. The child who has stopped trying because trying feels too risky needs to find a way back to the belief that their effort is worth making. That is delicate, patient work. But it is some of the most important work we do.

What Parents Can Do Right Now

The research suggests that the most effective interventions address not just the individual child but the environment around them. Professor Gemma Lewis said: "Current approaches to help pupils with mental health tend to be focused on helping individual pupils cope; we hope to address academic pressure at the whole-school level by addressing the school culture." UCL

As a parent, you cannot change school culture alone. But you can change the culture of home — and that matters more than most parents realise.

Some of the most helpful things you can do in the weeks ahead are also the simplest. Talk about effort, not outcomes. Notice what your child is doing well, and say so explicitly. Be curious about their experience of school rather than interrogating their results. Create space for them to be a person, not a performance. And if you are worried — if the signs described in this article feel familiar — take them seriously sooner rather than later.

The young people who navigate exam pressure and school transitions most successfully are not the ones without anxiety. They are the ones who have learned to work with it rather than be paralysed by it. That is a skill. And like any skill, it can be taught.

Frequently Asked Questions for Parents

My child says they are fine. Should I trust that? Sometimes yes. Often, the children who say they are fine are the ones who are working hardest to manage the pressure alone. Watch behaviour rather than words — the signs described in this article are often more reliable than self-report, particularly in older children and teenagers who have learned that admitting struggle feels vulnerable.

Is this just normal exam pressure? How do I know when it's something more? Normal pressure tends to be episodic — it rises before an exam and settles afterwards. The patterns to watch for are persistence and pervasiveness: stress that doesn't ease, that bleeds into friendships, sleep, appetite, and self-talk, and that is accompanied by a loss of pleasure in things your child usually enjoys.

My child already sees a counsellor. Would coaching add something different? Yes, in most cases. Counselling and coaching address different things. Counselling tends to focus on processing emotional difficulty; coaching is future-focused and strengths-based, working on what your child is capable of building rather than what they are struggling to process. The two work well alongside each other.

When is the right time to start coaching? Before it becomes a crisis. Coaching works best as a preventative investment — putting support in place now, as exam season approaches, gives your child the tools they need when the pressure peaks. The families who contact us in April for help with May exams often wish they had started in January.

Is coaching available online? Yes. We work with families online and in person, and increasingly on site at a number of independent schools in the UK.

The Conversation Worth Having

The research is clear. The stakes of exam stress extend well beyond the exam. But so does the impact of getting support right.
