Supporting Students with OCD at School: A Practical Guide for Educators
Obsessive-compulsive disorder (OCD) can have a significant impact on a child's experience at school. A student may appear distracted, oppositional, perfectionistic, slow to complete work, frequently leave the classroom, ask the same question repeatedly, or spend significant amounts of time washing their hands, checking their work, or completing routines. What can look like a behavioural problem may actually be an attempt to manage intense anxiety or uncertainty associated with OCD.
The good news is that OCD is highly treatable. Cognitive behavioural therapy (CBT), particularly a specialized approach called Exposure and Response Prevention (ERP), is considered a first-line psychological treatment for OCD and has been shown to be effective with children and adolescents.
Schools can play an important role in supporting treatment. However, educators should not independently create or implement an ERP plan. Strategies that involve reducing compulsions or intentionally tolerating anxiety should be developed collaboratively with the child's parents/caregivers and, ideally, the child's licensed therapist who has experience treating pediatric OCD.
First: Understand What OCD Is
OCD generally involves two components:
Obsessions are unwanted, intrusive thoughts, images, urges, or doubts that create distress.
Examples might include:
"What if I accidentally hurt someone?"
"What if I am contaminated?"
"What if I made a mistake?"
"What if something terrible happens?"
"What if I didn't lock that properly?"
"What if I said something offensive?"
"What if I don't feel completely certain?"
Compulsions are behaviours or mental rituals a person feels driven to perform to reduce distress or prevent something feared from happening.
Compulsions can include:
Repeated hand washing
Checking
Re-reading
Repeating words or actions
Asking for reassurance
Seeking confirmation from adults
Counting
Arranging objects
Avoiding certain situations
Confessing
Repeating schoolwork until it feels "just right"
Mentally reviewing an event
Saying phrases silently
Asking others to participate in rituals
Importantly, not all compulsions are visible. A student may look completely still while engaging in extensive mental rituals!
The OCD Cycle
One of the most useful concepts for educators is the OCD cycle, because sometimes educators are pulled into it:
Intrusive thought or doubt → anxiety/
discomfort → compulsion → temporary relief
→ OCD becomes stronger
For example:
"What if there are germs on my desk?"
The student becomes anxious.
They wash their hands.
Their anxiety decreases temporarily.
Their brain learns:
"Washing my hands made me safe and feel better."
The next time the thought occurs, the urge to wash may become even stronger.
This is why simply helping a child feel less anxious in the moment is not always helpful in the long term.
ERP works differently. Under the guidance of a trained therapist, the child gradually practices facing feared situations while reducing or resisting the compulsive response.
What Should Teachers Do?
The goal is not to make OCD disappear at school.
The goal is to support the student without accidentally strengthening OCD.
A helpful approach is:
Recognize OCD without shaming the student
When appropriate, use neutral language such as:
"It sounds like OCD is being really loud right now."
or:
"I wonder if this is OCD asking you to check again."
This separates the student from the disorder.
Instead of:
"Why are you doing that again?"
Try:
"I can see that you're feeling uncomfortable. Let's use the plan you've been working on with your parents/therapist."
The message is:
"You are not doing something wrong. Your OCD is asking you to do something that we are learning you don't need to do."
Reassurance Seeking: "Are You Sure?"
Reassurance seeking is one of the most common ways OCD can show up at school.
A student might ask:
"Are you sure I'm not in trouble?"
"Did I do this correctly?"
"Are you sure I didn't hurt someone?"
"Do you think I have enough information?"
"Are you sure the assignment is right?"
"Can you check this one more time?"
"Promise me I'm okay?"
"Are you absolutely sure?"
The natural response is to reassure the student.
"Yes, you're definitely fine."
Unfortunately, when reassurance is functioning as a compulsion, repeated reassurance can temporarily reduce anxiety while maintaining the OCD cycle. The International OCD Foundation specifically identifies excessive reassurance seeking as a behaviour that can reinforce OCD and recommends ERP-based approaches for breaking this cycle.
Instead of repeatedly reassuring:
Try a response that acknowledges the uncertainty without answering OCD's question.
For example:
Student: "Are you sure I didn't make a mistake?"
Teacher: "You really want me to tell you that you're definitely okay. I wonder if that's OCD looking for certainty."
Or:
"I don't think we need to solve that question right now."
Or, if this has been established as part of the student's treatment plan:
"Let's practice being okay with not knowing for sure."
Important distinction
Teachers should not refuse legitimate questions or intentionally withhold necessary information.
Not every question is reassurance seeking.
A child asking:
"What page are we on?"
needs an answer.
A child asking:
"Are you absolutely sure I won't get sick if I touch this?"
The distinction is often about function, frequency, urgency, and repetition.
This is exactly why educators should discuss the child's specific OCD presentation with the treating clinician before implementing a reassurance-reduction strategy.
Repetitive Hand Washing
Contamination fears can lead to significant hand washing at school.
A student may:
Wash their hands repeatedly
Wash for unusually long periods
Return to wash again
Avoid touching classroom materials
Ask others whether something is contaminated
Refuse to participate in activities involving shared materials
Use excessive amounts of sanitizer
Ask to leave class repeatedly to wash
What not to do
Avoid:
"Stop washing your hands."
or:
"You know your hands are clean. You don't need to do that."
Simply telling the student to stop can increase distress and may result in escalation.
Also avoid creating unnecessary accommodations that allow OCD to expand, such as providing unlimited opportunities to wash or repeatedly confirming that objects are clean.
What to do instead...
First, establish the student's treatment plan with their caregiver and OCD therapist.
The therapist may develop an ERP hierarchy that identifies situations the child can gradually practice tolerating without washing.
For example, treatment might eventually involve practicing touching a particular object and waiting before washing.
The teacher should not independently decide what exposure to introduce or how quickly to increase difficulty.
The school can then support the therapist-designed plan consistently.
Checking and Rechecking
OCD can also appear as excessive checking.
A student might:
Check an answer repeatedly
Re-read an assignment many times
Check their backpack repeatedly
Check whether they turned something in
Ask the teacher to verify their work
Check a door, locker, pencil case, or device
Restart an assignment because something "doesn't feel right"
The student may know that the checking is excessive but still feel unable to stop.
Instead of repeatedly checking for the student, consider language such as:
"You've already checked that according to your plan. Let's move forward."
Or:
"I notice OCD is asking you to check again. Let's follow the plan you and your therapist created."
Again, the specific number of checks or response should come from the student's treatment plan rather than being created by the teacher.
When a Student Says, "It Doesn't Feel Right"...
Not all OCD is about fear of contamination or something terrible happening.
Some children experience "just right" OCD, where something feels wrong, incomplete, uneven, or not quite right.
A student might:
Erase and rewrite repeatedly
Restart work
Rearrange objects
Repeat movements
Say something again until it feels right
Refuse to move forward until something feels perfect
It can be tempting to say:
"But it looks perfectly fine!"
That may accidentally invite the student to seek more reassurance.
Instead:
"I can see that it doesn't feel right to you. Sometimes OCD tells us something has to feel perfect before we can move on."
The treatment goal is not necessarily to make the student feel right. It is to help them learn that they can move forward even when something doesn't feel completely right.
What About Avoidance?
Compulsions are not always obvious.
A student may avoid:
Certain students
Certain classrooms
Bathrooms
Specific objects
Writing with a particular pencil
Touching shared materials
Eating
Using the school computer
Making mistakes
Answering questions
Participating in activities
Avoidance can function similarly to a compulsion because it prevents the student from learning that they can tolerate the feared situation.
Again, teachers should not force a student into feared situations as an informal exposure exercise.
Instead, communicate with the parents and treatment provider.
A therapist may determine that gradual exposure is appropriate and provide specific instructions for how school can participate.
Mental Compulsions Can Be Easy to Miss
One of the biggest challenges for educators is that OCD doesn't always look like repetitive behaviour.
A student may be sitting quietly while:
Reviewing a conversation in their head
Trying to determine whether they hurt someone's feelings
Repeating a phrase mentally
Counting
Praying
Checking memories
Trying to prove that they are a "good person"
Monitoring their thoughts or feelings
Trying to determine whether a thought means something about them
These behaviours can be particularly difficult to identify because the child may simply look distracted.
If a student repeatedly becomes stuck in these patterns, communicate your observations to the family and treatment team rather than assuming the student is simply inattentive or refusing to work.
A Helpful School Response: Support Without Accommodating OCD
There is an important difference between supporting a child and accommodating the OCD.
Supporting the child might look like:
Providing a predictable routine
Allowing access to a quiet space when needed
Using neutral language about OCD
Following the treatment plan
Giving appropriate processing time
Helping the student return to learning
Reinforcing effort rather than certainty
Communicating with caregivers
Encouraging the student to use skills taught in therapy
Accommodating OCD might look like:
Repeatedly answering the same reassurance question
Checking the student's work over and over
Participating in rituals
Allowing unlimited hand washing because the student is anxious
Completing rituals for the student
Changing classroom routines extensively to prevent OCD distress
Providing repeated confirmation that feared outcomes will not happen
The intention behind accommodation is usually compassionate.
The problem is that it can unintentionally teach OCD:
"The anxiety was dangerous, and the ritual was necessary."
What Teachers Can Say
Here are some simple phrases that can be helpful when they are consistent with the student's treatment plan:
When OCD is asking for reassurance
"I think OCD is asking you for certainty."
"I'm not going to help OCD get another answer."
"You don't have to figure this out with 100% certainty."
"Let's practice moving forward without checking again."
When the student is distressed
"I know this feels uncomfortable."
"You can handle this feeling."
"You don't have to make the uncomfortable feeling go away right now."
"I'm here with you while you practice."
When a student is resisting a compulsion
"This is hard, and you're doing something brave."
"The goal isn't to feel completely comfortable. The goal is to keep going even when OCD is uncomfortable."
Before Implementing Any ERP Strategy at School
This is perhaps the most important part of this article.
Teachers should not independently begin exposure exercises or abruptly prevent a child from completing compulsions.
ERP is a specialized treatment approach. Effective ERP involves assessment, individualized treatment planning, carefully selected exposures, response prevention, and consideration of the child's developmental level and specific OCD presentation.
Before changing how a student's OCD behaviours are handled at school:
Talk with the parents/caregivers.
Ask:
Is the child currently receiving treatment for OCD?
Who is their treating clinician?
What strategies are currently being used?
Are there specific compulsions the therapist has asked adults not to accommodate?
Are there specific ERP exercises that involve school?
What language does the therapist use with the child?
What should staff do if the child becomes highly distressed?
Whenever possible, collaborate directly with the treating clinician.
A simple school plan might identify:
The OCD behaviour:"Student asks the teacher to check their work repeatedly."
What staff should avoid:"Do not repeatedly check the work after the agreed-upon check."
What staff should say:"Your OCD is asking for another check. Let's use your plan."
What staff should encourage:"Continue with the next activity."
What staff should do if distress increases:"Follow the therapist's agreed-upon support plan and communicate with caregivers as appropriate."
This consistency between home, school, and therapy can be extremely helpful.
Should We Tell the Child That This Is OCD?
In many cases, yes, particularly when the child already has an OCD diagnosis and understands their diagnosis.
Using clear, non-shaming language can help children understand that the problem is OCD, rather than believing that there is something wrong with who they are.
Educators should follow the family's and treatment provider's approach regarding how the diagnosis is discussed with the child, particularly if the diagnosis is new or the child has not yet been informed.
The purpose of naming OCD should be to increase understanding and agency, not to dismiss the child's distress.
Remember: The Goal Is Not Zero Anxiety
One of the most important principles of ERP is that the goal isn't to make anxiety disappear.
If we respond to every uncomfortable feeling by trying to eliminate it, the child can learn:
"I need to feel calm before I can continue."
ERP instead helps children learn:
"I can feel anxious and still continue."
"I don't need to know for certain."
"I don't need to perform the ritual."
"I can tolerate discomfort."
This is an incredibly empowering message for students.
A Simple Framework for Educators
When you're unsure what to do, remember:
NOTICE
What is happening?
Is this potentially an obsession, compulsion, avoidance, or reassurance-seeking behaviour?
NAME
When appropriate, gently identify OCD.
"I think OCD might be asking you to check again."
VALIDATE
Acknowledge the emotion without validating the OCD's demand.
"I know this feels really uncomfortable."
DON'T FEED OCD
Avoid unnecessary reassurance, checking, or participation in rituals.
FOLLOW THE PLAN
Use the strategies established by the student's caregiver and OCD treatment provider.
RETURN TO LIFE
Help the student return to learning, relationships, play, and ordinary classroom activities.
The ultimate goal is not for OCD to dictate what the student can and cannot do at school.
The goal is for the student to have the opportunity to participate in school even when OCD is present.
Recommended Resources for Educators
Books
From Thoughts to Obsessions: Obsessive Compulsive Disorder in Children and Adolescents
This is particularly relevant for educators because it was written for parents, relatives, physicians, teachers, and other professionals. It provides an accessible explanation of OCD, assessment, and treatment without excessive clinical jargon.
Freeing Your Child from Obsessive-Compulsive Disorder, Revised and Updated Edition by Tamar E. Chansky, Ph.D.
Although written primarily for parents, this is an excellent practical resource for educators who want to understand pediatric OCD, compulsions, treatment, and how adults can respond without inadvertently reinforcing OCD. The revised edition was published in 2025.
Talking Back to OCD by John S. March, M.D.
This book provides a child- and family-friendly explanation of OCD and uses an ERP-based approach to help young people learn to resist compulsions. It can be useful for educators who want a better understanding of the language and principles children may be learning in treatment.
Evidence-Based Websites
International OCD Foundation (IOCDF)
One of the best starting points for information about OCD, ERP, pediatric OCD, treatment, and professional resources. The IOCDF also has a dedicated pediatric OCD resource site and educational programming for school professionals.
OCD in Kids
Designed specifically for children, families, school professionals, and clinicians. It includes information about pediatric OCD and ERP.
NICE: Obsessive-Compulsive Disorder and Body Dysmorphic Disorder
NICE provides evidence-based clinical guidance for OCD and related conditions and is a useful reference for understanding recommended treatment approaches.
A Final Reminder for Educators
You do not need to become an OCD therapist to be an important part of a student's support system.
Your role is often much simpler...
Understand the disorder.Recognize the cycle.Avoid accidentally strengthening compulsions.Use the language established by the treatment team. Support the student through discomfort.And help them get back to being a student.
Most importantly, do not try to implement ERP on your own. Any intentional reduction of compulsions, reassurance, avoidance, or accommodation should be coordinated with the child's caregivers and a licensed mental health professional with specific experience treating OCD using CBT and ERP.
When school, home, and therapy work together, students can learn something incredibly important:
"OCD can be loud, but it doesn't have to be in charge."
