Why Your Child Blanks Out During Exams – And How to Help

Your child studied hard. They knew the work. Then they sat down for the exam, looked at the first question, and their mind went blank.

This is one of the most common signs of exam anxiety in children and teenagers. It happens when stress hormones interrupt memory recall, even in students who know the material well. The good news: with the right preparation and support, most children can learn to manage it.

Quick summary:

• Blanking out is usually caused by anxiety, not lack of knowledge
• Good preparation, emotional readiness, and a clear exam strategy all help prevent it
• If it happens anyway, breathing techniques and skipping ahead can help your child recover
• Support after the exam matters as much as support before it

What Causes Blanking out During Exams in Children

Exam stress builds for different reasons. For school-leavers, it’s often the pressure of results shaping their future. Younger children may simply fear disappointing you or facing consequences for a poor mark.

Whatever the cause, the result is the same: anxiety interferes with the brain’s ability to recall information under pressure.

How to Help Your Child Prepare

1. Support Their Content Preparation

Strong study habits reduce the chance of blanking out. Encourage your child to:

• Pay attention in class and note hints teachers give about exam topics
• Ask teachers directly which areas to focus on
• Practise with past papers regularly

If your child struggles in a particular subject, a hand-picked tutor can help close knowledge gaps and explain things in a new way. A study skills course can also build confidence in how to study, not just what to study.

2. Help Them Prepare Emotionally

Academic readiness isn’t enough on its own. Emotional preparation matters too, especially for subjects your child finds hard. Try:

• Visualising the exam room and working through questions calmly
• Reminding them that doing their best is all anyone can ask
• Talking through a “what if” plan, so a disappointing result feels manageable, not catastrophic

3. Build an Exam Strategy Together

A simple strategy helps your child stay focused and manage time. Practise this with them:

• Read the whole paper before starting
• Answer the easiest questions first
• Leave time to review answers at the end

4. Look After Physical Wellbeing

The body affects the mind. Before exams, encourage your child to:

• Get enough sleep
• Stay active to reduce stress
• Eat brain-boosting foods like legumes, vegetables and nuts, and cut back on sugar and junk food

5. Arrange Exam Support If Needed

If your child has a learning barrier or similar challenge, apply for exam accommodations well in advance. Book a trained accommodation facilitator early to avoid last-minute stress.

Signs of Exam Anxiety to Watch For

Exam anxiety doesn’t only show up as blanking out in the exam room. Watch for signs in the weeks before, too – trouble sleeping, stomach aches on test days, irritability, or avoiding study altogether. According to Understood.org, test anxiety can look different at different ages, and it doesn’t always look like worry on the surface.

What to Do If Your Child Blanks Out Anyway

Even with good preparation, blanking out can still happen. Teach your child these steps:

• If they have a facilitator, tell them straight away so they can help.
• If they’re alone, remind themselves this isn’t life-threatening. Slow, deep breaths help.
• Turn the paper over, close their eyes, and breathe until it steadies.
• Move to another question. Leave space for the hard one and come back to it.
• Answer out of order if needed – but number every answer correctly. Examiners can’t mark a disorganised paper.

After the Exam: Help Them Move Forward

Once it’s over, avoid dwelling on it. A short debrief that identifies what caused the blank-out – and how to avoid it next time – is useful. Beyond that, let it go.

Exams are stressful, and most people don’t enjoy them. If exam stress keeps stopping your child from performing at their best, an exam accommodation or other neurodivergent support may help. If you’re using a tutor, ask them to help your child by building exam tips into their lessons. 

The key is taking action early. One exam result doesn’t define your child’s future – their success depends on far more than that.
