In school, OCD in a child tends to look like repeated checking, redoing work, frequent trips to the toilet, constant requests for reassurance, and work that takes far longer than it should. The rituals ease an anxiety that feels unbearable to the child, so blocking them or punishing them usually makes things worse. Staff don’t diagnose OCD. You notice, adjust, talk to home and pass your concerns on, and the GP and CAMHS do the assessing.
The rest of this post is what it looks like day to day, and what helps.
What is OCD, in plain terms?
Obsessive compulsive disorder is an anxiety disorder. It can be serious, and it’s treatable.
It has two parts, though a child may not have both. Obsessions are the thoughts, images or urges that keep coming back uninvited: a fear of germs, a worry that something terrible will happen to someone they love, a number that feels unlucky. Compulsions are what the child feels they have to do to make the feeling go away. That might be washing their hands again, switching a light on and off a set number of times, repeating a phrase in their head, or checking their pencil case for the fourth time.
Everyone has small rituals, and some of them help (slow breathing when you’re nervous is one). It becomes a problem when the rituals get in the way of ordinary life. Around 12 in every 1,000 people have OCD, from young children to adults.
What are the signs of OCD in a child at school?
With younger children, parents often notice first. Getting dressed takes an age, or the morning routine falls apart. In school, the signs tend to be:
- work that takes much longer than it should, or is rubbed out and rewritten until it’s “right”
- work thrown in the bin over a tiny mistake, or real anger about its quality
- a strong need for order, neatness or cleanliness, and a fear of dirt or germs
- repeated checking of bags, pencil cases, or that something has been done
- asking to go to the toilet again and again (often to wash hands)
- asking for reassurance over and over
- tiredness, lateness, or not wanting to come in at all
Some children have intrusive thoughts that frighten them: about losing control, about harming themselves or someone else, or thoughts of a violent or sexual kind. These thoughts are unwanted and distressing, which is exactly why the child may pray, confess or seek reassurance to cancel them out. If a pupil tells you about thoughts like these, listen calmly, don’t promise to keep it secret, and follow your school’s safeguarding procedures by passing it to your DSL. The DSL and the professionals involved are the right people to judge what it means.
Older children are often better at hiding it, so you may see the effects before you see any ritual: exhaustion, low self-esteem, embarrassment, falling behind. Some will have been up half the night with it. Watch for other pupils noticing the behaviour, too, because that can lead to bullying.
Why does stopping the ritual make it worse?
This is the bit that changes how staff respond. A compulsion brings relief. The anxiety drops, so the brain learns that the ritual works, and next time the urge is stronger. Avoiding whatever triggers the fear works the same way. It’s a loop, and the child can’t simply decide to step out of it.
So if a teacher says “No, you can’t go to the toilet again” or “Stop rewriting it and hand it in”, the anxiety goes up, not down. The child isn’t being defiant and isn’t dodging the work. OCD isn’t deliberate, and a disciplinary response makes it worse. Every adult who works with the child needs to know that.
Breaking the loop properly is a job for trained clinicians. What school can do is avoid feeding it and give the child other ways to cope.
Who should I tell if I think a pupil has OCD?
Start with your school’s own route. That’s usually the SENCO or the mental health lead, and the DSL if anything worries you about safety. Talk to parents or carers too. They’ll know what happens at home, which is often where the worst of it shows.
The family’s GP is the usual first step towards an assessment, and from there a referral to CAMHS. Your notes on what you’ve seen in school (when, how often, what seemed to set it off) are useful evidence for that conversation. Leave the label to them.
How can teachers help a pupil with OCD in class?
Most of what helps is simple and costs nothing:
- agree a quiet spot, in the classroom or elsewhere with an adult nearby, that the child can go to when it’s getting too much
- offer a distraction that breaks the moment, like running an errand, a short walk or a brief break from the task, in the way you’ve agreed with the family or the child’s clinician
- help the child know what to do when things build up, so they’re not left stuck
- make sure every adult who teaches them knows, including supply and cover staff, so nobody punishes the behaviour
- set realistic expectations, and build on what they’re good at
The course’s protective factors are worth leaning on too, because they can help a young person cope and feel good about themselves. Physical activity and sport can give feelings somewhere to go. Achievements in or out of lessons can help as well, along with a sense of being good at something and being taught that asking for help is a sensible thing to do.
Some schools teach the whole class about OCD so peers are kinder. That can help, but ask the parents (and the child, if they’re old enough) first.
Supporting teenagers with OCD: exams, maths and keeping a log
With older pupils, give them as much control as you can. Ask whether a compulsion is distressing them or getting in the way, rather than assuming. Help them find a trusted adult they can go to when the urges are strong, such as a learning mentor, the school counsellor or the nurse.
A few practical things come up again and again at secondary:
- If the need for perfect handwriting means a pupil can’t finish a paper, talk to your SENCO and exams officer about whether access arrangements, such as typing answers, might apply. JCQ’s rules decide what’s allowed.
- Some pupils are frightened of numbers they see as unlucky. Maths staff can work with them, gently, so they learn they’re safe to use that number.
- Keeping a log of thoughts, feelings and what was happening at the time helps the pupil, the family and the school spot triggers.
Expect progress and relapse both. Support can be eased off as confidence grows, but a bad week doesn’t mean it’s failed.
Why OCD training for school staff matters
The hardest part is often getting every adult to respond the same way. One teacher who blocks the toilet trips or tells a pupil off for rewriting can undo a lot of patient work. That’s why short OCD training for the whole staff team is worth more than one well-informed person. If you’re looking for more on pupils’ mental health, there’s plenty on our health and wellbeing topic page.
Our course, Spot and Support: Obsessive Compulsive Disorder, is a short online CPD course for teachers, teaching assistants, pastoral staff and leaders. It covers what OCD is, what the signs look like, the risk and protective factors, and how to support younger children and teenagers. A handout follows each module. See the course.
