What Are Executive Functions and Why Do They Matter for My ADHD Child?
Warning: contains an extended air traffic control metaphor and at least one reference to a sock drawer
Right. Executive functions.
You have heard this phrase approximately forty-seven times since your child's ADHD diagnosis. It has appeared in school reports, been mentioned by professionals in meetings, and features heavily in every book about ADHD that you have bought, started, and left face-down on the bedside table.
And yet nobody has actually explained what it means in a way that makes you think "ah, THAT'S what's going on."
Until now. Hopefully. Let's go.
The Air Traffic Control Tower Your Child Didn't Fully Get
Imagine a busy airport.
Planes everywhere. Runways. Gates. Fuel trucks. Baggage handlers. Thousands of passengers trying to get somewhere. An enormously complex system with approximately nine thousand moving parts.
Now imagine the air traffic control tower.
The tower does not fly the planes. It does not load the luggage or serve the drinks. What it does is manage everything else — directing traffic, sequencing landings, communicating with pilots, making sure nobody ends up on the wrong runway at the wrong time.
Without the tower, you do not have chaos instead of order. You have chaos instead of an airport.
Executive functions are the air traffic control tower of the brain.
They do not make a child clever. They do not give a child knowledge or creativity or personality. What they do is manage those things — directing attention, sequencing tasks, communicating between different parts of the brain, making sure the right thing happens at roughly the right time.
In ADHD, the tower is understaffed.
The planes are all there. The intelligence is there. The capability is there. But the management system that deploys all of that capability reliably and efficiently is working with a skeleton crew, no coffee, and a broken intercom.
Which explains rather a lot.
The Eleven Executive Functions — A Plain English Field Guide
There are eleven of them. I am not going to make this a list you skim and forget. I am going to explain each one in the way that makes it stick.
1. Response Inhibition — The Internal Brake
What it is: The ability to stop and think before acting. The pause between impulse and action.
What it looks like when it works: Child thinks about saying the very funny but deeply inappropriate thing in class. Does not say it. Files it away for home.
What it looks like when it doesn't: Child says the very funny but deeply inappropriate thing in class. Teacher is not amused. Child is genuinely surprised by this outcome. Again.
This is not rudeness. This is a brake that takes longer to engage than other people's. The thought and the mouth have met before the filter has had a chance to intervene.
2. Working Memory — The Mental Whiteboard
What it is: The ability to hold information in mind while actively using it.
What it looks like when it works: Parent says "get your shoes, put your water bottle in your bag, and get in the car." Child does all three things.
What it looks like when it doesn't: Parent says "get your shoes, put your water bottle in your bag, and get in the car." Child gets their shoes. Spots a Lego brick. Thinks about Lego for four minutes. Gets in the car without their water bottle. Has no memory of being told about the water bottle.
The water bottle information was not retained. It is not that they did not hear it. It is that working memory is the brain's whiteboard, and in ADHD the whiteboard gets wiped mid-sentence.
3. Emotional Control — The Volume Knob
up significWhat it is: The ability to manage feelings so they don't manage you.
What it looks like when it works: Child is disappointed about something. Feels the disappointment. Expresses it proportionately. Moves on within a reasonable timeframe.
What it looks like when it doesn't: Child is disappointed about something small — the wrong flavour crisps, a sock with a seam, a Minecraft structure that did not go to plan — and the reaction suggests the actual end of the world may be upon us.
The feeling is real. The intensity is genuine. The volume knob — the internal system that keeps emotional reactions proportionate to the situation — is turned antly higher than average and does not always come back down quickly.
This is not drama. It is a neurological difference in how emotions are experienced and processed. The disappointment feels as enormous as it looks from the outside.
4. Sustained Attention — The Sitting Still Part of the Brain
What it is: The ability to stay on task even when it is not immediately interesting or rewarding.
What it looks like when it works: Child does the worksheet. All of it. Without being asked seven times.
What it looks like when it doesn't: Child starts the worksheet. Notices something on the ceiling. Thinks about whether spiders sleep. Wonders if their friend Jake is at home. Draws a small horse in the margin. Is genuinely surprised to be told they have done two questions in twenty minutes.
The capacity for attention is not absent in ADHD. The selective nature of it is the issue — full, intense, locked-on attention for things that are interesting, and almost no reliable attention for things that are not. This is sometimes described as a regulation problem rather than a deficit. The attention is there. The ability to direct it at will is not.
5. Task Initiation — Starting Things
What it is: The ability to begin tasks without procrastinating indefinitely.
What it looks like when it works: Child is told to start their homework. Child starts their homework.
What it looks like when it doesn't: Child is told to start their homework. Child sits in front of homework. Looks at homework. Looks away from homework. Gets a drink. Comes back. Looks at homework. Sharpens three pencils. Wonders if they need to go to the toilet. Sits back down. Forty-five minutes have passed. Not one word has been written.
This is not laziness. I cannot stress this enough. The ADHD brain genuinely struggles to initiate tasks that are not immediately interesting, urgent, or anxiety-inducing. It often needs a deadline looming with sufficient threat level before it can generate the activation required to begin. This is why your child who "cannot do anything" can stay up until midnight finishing a project that is due tomorrow. The urgency is the fuel.
6. Planning and Prioritisation — The Knowing Where to Start Bit
What it is: Working out what needs to happen, in what order, and what matters most.
What it looks like when it doesn't work: Child is given a project. Child does the colouring on the front cover with great care and attention. Hands in a beautifully illustrated project with the actual content missing. Not because they did not care. Because they could not see where to start and the colouring was there and accessible.
7. Organisation — The Sock Drawer of the Mind
What it is: Keeping track of things, spaces, belongings, and information.
What it looks like when it doesn't work: The school bag that appears to eat things. The bedroom that looks like a small but determined tornado has been through it. The PE kit that is definitely somewhere. The planner that has never, to anyone's knowledge, been opened at home.
This is not deliberate. An organised space requires an organised mind — specifically, a mind that can hold a system in place over time. When that system is not naturally maintained internally, the external world reflects it.
The solution is not "try harder to be tidy." It is external systems — a place for everything, a routine that does not rely on remembering, an adult who checks without making it a character judgement.
8. Time Management — Time Is a Concept That Happens to Other People
What it is: Understanding that time is passing and acting accordingly.
What it looks like when it doesn't work: It is 8.25am. School starts at 8.45am. Your child is in their pants looking at a Pokémon card.
The ADHD brain famously experiences time as either NOW or NOT NOW. The future — even the very near future — is abstract and not particularly motivating. The transition from "we have plenty of time" to "we are catastrophically late" happens without warning because the brain has not been tracking the time passing in between.
Clocks help. Timers help. Warnings help. Internalised time awareness does not arrive reliably until much later than in neurotypical children — if at all.
9. Goal-Directed Persistence — The Finishing Things Bit
What it is: The ability to keep working toward a goal even when it is hard, boring, or progress is slow.
What it looks like when it doesn't work: The half-finished model. The abandoned hobby. The book that was loved until chapter four. The project that was started with great enthusiasm and is now living under the bed with the PE kit.
The ADHD brain is brilliant at starting things that are exciting. It is significantly less reliable at continuing things once the novelty has worn off and the actual work part has begun.
10. Flexibility — The Plan Changed and the World Has Ended
What it is: The ability to adapt when things change or do not go to plan.
What it looks like when it doesn't work: The school trip that was postponed. The friend who cancelled. The dinner that was the wrong pasta shape. The reaction to any of the above being significantly larger than the event would suggest it warranted.
The ADHD brain, having put considerable effort into holding a plan together, does not relinquish that plan gracefully. The plan was the structure. Without the structure, everything is uncertain. The reaction is not about the pasta.
11. Metacognition — Thinking About Your Own Thinking
What it is: The ability to stand back and evaluate how you are doing and adjust accordingly.
What it looks like when it doesn't work: "I know all of this, I don't need to revise." Fails the test. Genuinely shocked.
Metacognition is the brain's ability to observe itself — to know what you know, recognise when you are off track, and adjust your approach. When it is impaired, a child has no reliable internal feedback system. They cannot accurately assess their own performance, preparation, or understanding.
Which is why "did you understand that?" is not a reliable question. They think they did. That is the point.
The Bit That Changes Everything
Here is what Russell Barkley's research tells us — and what every parent, teacher, and professional working with an ADHD child needs to know.
Executive function skills in ADHD are delayed by approximately 30% compared to neurotypical peers.
Not absent. Not broken forever. Delayed.
Your 10-year-old is managing their impulses, emotions, time, and organisation with the executive function capacity of roughly a 7-year-old.
Your 14-year-old is navigating secondary school, GCSEs, and adolescence with the executive function capacity of roughly a 10-year-old.
This does not mean low expectations. It means realistic expectations — and the right scaffolding while the development catches up.
You would not expect a child who is 30% shorter than their peers to reach the same shelf without help. You would move the shelf, or provide a step.
Executive function support is the step.
The Thing Schools Need to Hear
When a school tells your child to "try harder to be organised" or "take more responsibility" without any support in place — they are asking a child with a broken internal scaffold to build the house from the inside.
You are entitled, under the Equality Act 2010 and the SEND Code of Practice, to ask what reasonable adjustments are in place for your child's executive function difficulties. That is a legal question, not a difficult parent question.

In Summary
Executive functions are the brain's management system. ADHD affects all of them to varying degrees. The 30% developmental lag means your child is working significantly harder than it looks — and needs support, not more effort, to bridge the gap.
Once you understand this, everything changes. The water bottle is not defiance. The missing homework is not laziness. The meltdown over the pasta shape is not manipulation.
It is an understaffed air traffic control tower doing its best with what it has got.
And with the right support, the staffing gets better.
