"He could organize himself if he really wanted to." This phrase, spoken in countless class councils about autistic students, perfectly summarizes the central misunderstanding surrounding executive functions in autism. It attributes to willpower what is neurological in nature. It confuses a real difficulty with a lack of motivation. And it directs responses towards punishment and injunction rather than adaptation and support.
Executive functions are the set of cognitive processes that allow us to plan, initiate, organize, regulate, and control our behaviors towards a goal. They are often described as the "conductor" of the brain — they do not produce the music themselves, but they coordinate all the musicians to make it coherent. In autism, this conductor functions differently — with real strengths in some areas and significant weaknesses in others.
This third article in the series explores in detail the executive functions in the autistic profile: what they are, how they function differently in autism, why secondary school particularly tests them, and what concrete adaptations allow the autistic student to compensate for them effectively.
1. What are executive functions?
Executive functions are a set of high-level cognitive processes, primarily located in the prefrontal cortex, that allow an individual to direct their behavior towards a goal — by inhibiting distractions, planning steps, adapting to obstacles, and regulating their own emotions and impulses during the task. They develop throughout childhood and adolescence, and do not reach full maturity until adulthood — around 25 years for the prefrontal cortex.
In daily school life in middle and high school, executive functions are constantly called upon: noting homework in a planner, preparing a backpack for the next day, starting an assignment at home without being reminded, managing time during an assessment, switching from one subject to another between classes, managing frustration without reacting impulsively. All these seemingly simple tasks rely on this executive system — and when this system functions differently, as is often the case in autism, these ordinary tasks become major obstacles.
💡 A useful analogy: GPS and the driver. Executive functions are like an internal human GPS. They define the destination (the goal), calculate the route (planning), recalculate in case of obstacles (flexibility), maintain attention on the road (inhibition of distractions), and manage fuel (emotional resources). A student with weakened executive functions is not a bad driver — they are a driver whose GPS works differently, who needs an external GPS (tools, routines, adult support) to reach the same destination.
2. Autism and executive functions: a complex relationship
The relationship between autism and executive functions is more nuanced than what is sometimes read. It would be inaccurate to say that "autistic people have deficient executive functions" — the reality is more complex and interesting. Executive profiles in autism are typically very heterogeneous: some executive functions may be remarkably developed, while others are significantly weakened. The same student may have exceptional working memory for factual information and great difficulty initiating a task or transitioning from one activity to another.
This heterogeneity is precisely what confounds untrained teachers. A student who accurately retains the content of ten history chapters but is unable to submit their homework on time seems simply "disorganized." A student who can meticulously plan their activities related to their specific interest but finds themselves paralyzed in front of a free writing task seems "unmotivated." In both cases, what the teacher observes is actually a heterogeneous executive profile — not a lack of will.
Research in neuroscience has identified particularities in several executive domains in autistic individuals: frequent difficulties with cognitive flexibility (switching from one task to another, adapting to changes), with initiation (starting a task even when knowing what to do), and with planning complex multi-step tasks. These difficulties often coexist with real strengths in other areas: sustained attention on topics of interest (hyperfocus), precision and systematicity in well-defined tasks, memory for details and rules.
3. The six key executive functions and their impact in secondary school
- Difficulty stopping on a topic of passion to switch to the assigned task
- Unfiltered interventions in class (saying what one thinks without filtering)
- Difficulty ignoring distracting stimuli from the environment
- Task changes perceived as abrupt interruptions
- Great difficulty in changing methods when the first one does not work
- Strong reaction to changes in schedule or room
- Difficulty in considering multiple solutions to an open problem
- Rigidity in group work (insistence on "the right way")
- Loses track of a long oral instruction
- Difficulty doing several things simultaneously (listening and taking notes)
- Forgets intermediate steps in complex tasks
- Working memory often very strong for content of interest
- Assignments not submitted despite a good understanding of the content
- Inability to estimate the time needed for a task (under or overestimation)
- Major difficulties with long-term projects (presentations, research projects, large assignments)
- Materials frequently forgotten or poorly prepared
- Paralysis in front of a blank page even with ideas in mind
- Need for a "click" or external structure to begin
- Unintentional procrastination: knows what to do, does not start
- Almost immediate start on intensely interesting topics (hyperfocus)
- Emotional reactions perceived as disproportionate by outsiders
- Difficulty recovering after frustration or an unexpected event
- Very intense emotions but sometimes not visible (internal regulation)
- Anxiety anticipates and amplifies executive difficulties
4. Why secondary school amplifies executive difficulties
Primary school, despite its demands, provides a relatively structured framework for students with executive difficulties: a main teacher who knows the student, a stable schedule, few transitions, relatively short and clear tasks. Middle and high school remove most of these protective factors.
The increase in teachers means an increase in teaching styles, ways of giving instructions, evaluation formats, and implicit rules to decode. For an autistic student whose procedural memory is already maximally engaged, learning the work habits of 9 different teachers represents a considerable cognitive load. The communication notebook and agenda — external organizational tools — assume a consistency in their use that executive fragility makes difficult to maintain. Long-term projects (presentations, research projects, large homework assignments) require precisely the planning skills that are often the most fragile. And transitions between classes — five to ten times a day depending on the schedule — are moments of disruption that require an effort to adapt each time, which neurotypical students perform almost automatically, but autistic students must produce consciously.
Executive difficulties do not add up — they multiply. A student who struggles to initiate tasks, organize time, manage transitions, and regulate emotions in the face of frustrations experiences each day at school as an obstacle course. By the end of the day, they are exhausted — not because they have worked hard, but because they have expended disproportionate energy on tasks that their peers accomplish automatically. This exhaustion further reduces the executive resources available for evening homework — creating a vicious circle from which the student cannot escape alone.
5. Observable signals in class: what the teacher sees
| Observed behavior | Concerned executive function | Frequent misinterpretation |
|---|---|---|
| Homework not submitted despite a good understanding of the lesson | Initiation, planning, prospective memory | "Lack of seriousness" / "Bad will" |
| Disproportionate reaction to a schedule change | Cognitive flexibility, emotional regulation | "Immaturity" / "Difficult character" |
| Blank sheet for 20 minutes despite knowledge | Initiation, production planning | "Laziness" / "Psychological block" |
| Agenda never filled or filled in an unusable way | Planning, prospective memory, organization | "Disorganized by nature" / "Parents do not follow up" |
| Inability to move on to the next task when absorbed by the previous one | Inhibition, cognitive flexibility | "Does not follow instructions" / "Stubbornness" |
| Materials regularly forgotten or poorly prepared | Planning, prospective memory | "Irresponsible" / "Parents do not check" |
| Projects submitted at the last minute or not at all | Long-term planning, time management | "Procrastination" / "Poor voluntary time management" |
| Excellent on topics of interest, absent on others | Selective initiation related to intrinsic motivation | "Selective" / "Could do better if they wanted to" |
6. The paradox of the intelligent student who "does not organize"
The most common paradox in autism in secondary school is precisely this: a student who demonstrates real intellectual abilities — who understands lessons, who can accurately discuss complex topics, who masters content that their peers struggle to acquire — but who does not submit their homework, forgets their materials, arrives without their things, and has no plan for the presentation due in two weeks.
This paradox is incomprehensible to the untrained teacher, who naturally concludes that the student "could if they wanted to" — and whose sanction reinforces this conclusion: if poor grades do not motivate them to organize, it is because they really do not want to. This reasoning is logical — and false. It ignores that the ability to organize and the ability to understand are two distinct cognitive systems. Understanding involves long-term memory and reasoning — areas often preserved in autism. Organization involves executive functions — an area often weakened. Intelligence does not compensate for executive functions. It may temporarily mask them — but it does not replace them.
I knew exactly what I had to do for the presentation. I had the sources in my head, the outline, the arguments. I didn't submit it because I couldn't get started. Every evening I told myself "tonight I start" and every evening something happened — the noise, the fatigue, the anxiety of the blank page. On the D-day, I told my teacher that I hadn't finished. He told me that I lacked effort. I didn't know how to explain to him that I had spent two weeks thinking about this presentation without being able to write it. I didn't even have the words to describe it myself.
7. Adapt the organization: tools and concrete strategies
Adaptations for executive difficulties in autism all aim for the same objective: to externalize what the autistic brain struggles to do internally — create explicit, visible, stable, and predictable organizational systems that replace the failing "internal conductor."
- The visual schedule displayed on the desk. A weekly schedule, permanently displayed on the student's desk (or in a corner of the classroom), with subjects, rooms, and materials needed for each class. This visual support externalizes daily planning and reduces the cognitive load of transitions.
- The checklist for preparing the backpack. A laminated checklist displayed in a fixed location — at home or in the student's locker — listing the materials needed for each day of the week. Simple, inexpensive, effective. The student "checks off" each item before leaving.
- The digital or shared notebook. Rather than asking the autistic student to fill out a planner (a task that requires simultaneous attention to the teacher's speech AND note-taking AND adhering to the planner's format), a digital notebook shared with the family allows for checking homework without relying on the student's fragile prospective memory.
- The confirmation of instructions in writing systematically. Any instruction given orally must be confirmed in writing — on the board, on a distributed sheet, or via a digital platform. The autistic student cannot rely on their auditory working memory for long or complex instructions.
- A stable and dedicated workspace. At home, a fixed workspace, with the same materials always in the same place, reduces startup time and the burden of ancillary decisions (where to sit, where is my pen) that exhaust executive resources even before work begins.
8. Adapt the management of long tasks and projects
Long tasks — presentations, reports, TPE, major essays — are the most ruthless ground for expressing planning difficulties in autism. They require precisely the most fragile skills: defining steps, estimating durations, initiating each sub-task, maintaining focus on the final goal over several weeks.
Break down the task with the student
Rather than a presentation due in three weeks, the teacher can co-construct a detailed action plan with the student: "Week 1: choose the topic and find 3 sources. Week 2: create the outline and write part 1. Week 3: write parts 2 and 3, prepare the slides." Each step has an intermediate due date — which transforms a task with a horizon too distant to trigger initiation into a series of short, immediately actionable tasks.
The intermediate progress points
A weekly 5-minute check-in — "where are you, do you need help starting the next step?" — helps identify blockages before they lead to total abandonment. This is not "policing" — it is providing external executive support that temporarily compensates for what the autistic brain struggles to do alone.
Offer alternative formats
A presentation can be replaced by an oral presentation with visual support, a written report, a multimedia production, or a practical demonstration. These alternatives do not reduce the requirement — they allow the student to demonstrate their skills in a format that bypasses the most significant executive obstacles for them.
9. Manage transitions and changes
Each transition — between two classes, between two activities in the same class, between two weeks of work — requires cognitive flexibility and inhibition capabilities. For autistic students whose functions are fragile, transitions are moments of vulnerability that can be significantly managed.
Announcing a change without warning. Abruptly interrupting an activity in which the student is engaged. Changing the usual order of the lesson without announcing it. Replacing a teacher without notifying the student the day before.
Announcing transitions in advance ("in 5 minutes, we will move on to exercise 3"). Displaying the course outline on the board from the beginning. Informing about program changes at least 24 hours in advance. Allowing a longer transition time than for other students (not rushing).
10. Digital tools for executive functions
| Digital tool | Supported executive function | Concrete application |
|---|---|---|
| Visual timer (Time Timer) | Time perception, transition management | Placed on the desk during assessments and long tasks — makes time visible and predictable |
| Task management app (Todoist, TickTick) | Planning, prospective memory | Homework list with due dates, subtasks for large projects, automatic reminders |
| Shared digital calendar (Google Calendar) | Time organization, anticipation | Schedule, assessment dates, exceptional events — shared with families |
| Voice note-taking app | Working memory, initiation | Dictating ideas before writing them down — bypasses writer's block |
| Word processor with visible outline | Planning written production | Writing directly in a document with pre-established section titles — externalizes structure |
| Mind mapping app (MindMeister, Coggle) | Idea organization, planning | Visual brainstorming before writing, externalized project plan |
| Pomodoro timer (25 min work / 5 min break) | Initiation, attention support, regulation | Structures homework time into predictable blocks that facilitate starting |
11. Practical cases: executive functions in real school situations
Nathan, 16 years old, diagnosed with autism in 8th grade, is enrolled with two classmates for a physics TPE. The topic is validated in the first month. On the due date, three months later, Nathan has produced nothing. His classmates did the work without him. His grades in physics are excellent. His main teacher is convinced that he "slacked off" on the work.
During a meeting with the family and the student, Nathan explains: he had the topic in mind constantly, he had the ideas, but every time he sat down to start, he didn't know "where to begin" and ended up doing something else. He didn't ask for help "because he thought it would come." The teacher understands: this is a classic initiation deficit in autism.
✅ Implementation: For the rest of the year, the main teacher establishes with Nathan a planning sheet for each major assignment: 3 to 5 steps with intermediate dates, and a 5-minute check-in per week via message or in person. Nathan delivers his oral presentation on time — with remarkable content quality. His teacher: "He had everything in his head from the beginning. He just lacked the path."
Inès, 14 years old, ADHD with a masking profile, regularly forgets her materials and assignments. Her parents check her agenda every evening — but it is often empty or filled out in an unreadable way. The literature teacher, after a DYNSEO training, understands that filling out an agenda requires simultaneous attention that Inès's working memory cannot provide at the end of class.
She proposes a simple solution: a class group on the ENT, in which she publishes the assignments and necessary materials for each class within 5 minutes after the end of the session. Inès no longer needs to fill out an agenda — she checks the group. Her mother confirms the assignments via the same channel. The teacher extends the practice to the entire class.
✅ Result: The rate of assignments submitted by Inès increases from 45% to 90% in two months. Five other students in the class — without an ADHD diagnosis but with organizational difficulties — also benefit in the same way from the ENT group. The teacher: "I solved Inès's problem and improved the organization of the entire class. It took me 5 minutes per week."
Mathis, 15 years old, autistic, almost systematically goes into crisis during transitions between activities during the SVT class. His teacher, who frequently changed activities without warning ("we are now going to do the exercises"), perceived these crises as deliberate provocations. After training, he understands: Mathis is in full inhibition of a task and his brain needs a warning to prepare for the transition.
He adopts a simple practice: announcing the course outline on the board at the beginning of the session (10 min lecture / 15 min lab / 10 min correction), and saying "in 3 minutes we will move on to the exercises" before each change. He gives Mathis a visual timer for the activity moments.
✅ Assessment: Mathis's crises in SVT disappear in two weeks. His teacher: "I literally needed 30 seconds per transition to announce what was coming next. These 30 seconds eliminated incidents that sometimes cost us 15 minutes of class. I don't understand why I wasn't doing this before."
Executive functions in autism are the least visible dimension and the most structurally impactful on secondary education. Understanding that "not being organized" is not a choice but a neurological reality radically transforms the way the teacher can help — shifting from punishment to tools, from injunction to adaptation. The following article in this series explores another fundamental dimension of the autistic profile in secondary education: social interactions in adolescence, the most complex and painful area for most autistic students.
