They Know What to Do…So Why Can't They Get It Done?

Your child knows the homework is due tomorrow but doesn't start. They understand the morning routine but still need reminders for every step. They studied the material but forgot there was a test. They can explain exactly what they should be doing, yet following through is consistently difficult.

These patterns can reflect difficulties with executive functioning, the skills involved in starting tasks, organizing information, managing time, and following through.

What Is Executive Functioning?

Executive functioning refers to the skills that help us manage our behaviour, organize information, and carry out tasks (our “getting stuff done” skills).

Think about getting ready for school in the morning. A child needs to remember what belongs in their backpack, keep track of time, move between several activities, and resist getting distracted along the way. Knowing the routine is only one part of managing it independently.

  • get started

  • focus and shift attention

  • remember what they need to do

  • plan and prioritize

  • organize materials and information

  • manage time

  • work through multiple steps

  • notice mistakes

  • adjust when something isn't working

  • finish what they started

What Does Executive Functioning Difficulty Look Like in Children and Teens?

They don't always look like an obvious attention problem. More often, parents notice everyday patterns.

  1. “They just won't start.” Homework is sitting in front of them, but twenty minutes pass before anything happens. Large or open-ended assignments feel especially difficult. This may reflect difficulty with task initiation (i.e., figuring out where to begin and getting into action).

  2. “They forget everything.” Instructions disappear. Permission forms stay in backpacks. Your child walks upstairs to get something and returns without it. Working memory helps us hold information in mind long enough to use it. When that system is overloaded, a child can genuinely intend to do something and still lose track of it.

  3. “Their backpack, locker, and room are a disaster.” Papers disappear. Assignments are completed but not handed in. Materials seem to migrate everywhere except where they belong. Organization requires a child to create and maintain systems, not simply understand that they should be more organized.

  4. “Everything takes longer than it should.” Getting ready for school takes 45 minutes. A short homework assignment consumes the evening. Your child consistently underestimates how long something will take. This can reflect difficulty with time awareness, planning, attention, or managing multiple steps efficiently.

  5. “They rush and make careless mistakes.” Your child understands the work but skips instructions, misses signs in math, overlooks part of a question, or submits an assignment without checking it. Self-monitoring (i.e., slowing down, noticing what's happening, and checking the result) is also an executive skill.

  6. “They can do it sometimes. Why not every time?” This is one of the most confusing patterns for parents. Executive functioning difficulties can be inconsistent. Interest, structure, novelty, fatigue, stress, distractions, and how much support is available can all affect performance. Being able to do something under ideal conditions doesn't necessarily mean a child can manage it independently and consistently.

Is Executive Functioning the Same as ADHD?

No. Executive functioning difficulties are common in children with ADHD, but they are not unique to ADHD. Similar difficulties can occur when a child is anxious, overwhelmed, tired, struggling academically, or managing demands that exceed their current skills. That's why behaviours such as procrastination, forgetfulness, disorganization, and poor follow-through aren't enough on their own to determine whether a child has ADHD. The pattern and the reason behind it matters.

Is It Executive Functioning or Motivation?

All children sometimes avoid tasks they dislike. I become more interested in executive functioning when the same difficulties occur repeatedly, including during activities the child genuinely wants to complete. They may be excited about a school project but struggle to organize the materials, begin the work, or finish it on time. Their interest in the outcome does not necessarily translate into an ability to manage the process.

Consider whether your child or teen:

  • knows what needs to happen but can't seem to get started

  • repeatedly forgets despite consequences and reminders

  • needs significantly more prompting than expected for their age

  • becomes overwhelmed by tasks with several steps

  • struggles to use organizational systems without ongoing adult support

  • performs much better when someone else provides the structure

When Should Parents Look More Closely?

Executive functioning develops throughout childhood and adolescence, and some forgetfulness, procrastination, and disorganization are expected along the way. The goal is to understand whether a child has the skills and support they need to meet the demands of daily life. It may be worth looking more closely when these difficulties:

  • happen frequently

  • are greater than expected for your child's age

  • occur at both home and school

  • interfere with learning or everyday routines

  • require substantial adult support

  • continue despite strategies and structure

  • create ongoing frustration or conflict

Can a Psychoeducational Assessment Look At Executive Functioning?

When executive functioning is a concern, assessment can explore skills such as working memory, planning, attention, inhibition, and the ability to adjust when something is not working.

I also want to understand what happens outside the assessment room. A child may manage a structured, one-on-one activity quite well but struggle considerably when expected to organize assignments, remember responsibilities, or manage several demands independently. Information from parents and teachers helps connect the assessment findings to those everyday experiences.
