What Are the Developmental Norms for Executive Function Skills?

Before you decide a behavior is a choice, it helps to know what’s actually reasonable to expect.

This is one of the questions I get asked most, by parents and educators alike. Once people understand that Executive Function skills drive behavior, it’s reasonable to wonder what to expect at different ages.

And, of course, underneath that question is often a bigger one: is this a child who won’t, or a child who can’t? perform an expected behavior.

Here’s the chart I use to talk about the nine Executive Function skills – the “Board of Directors” that helps a child do what they’ve decided to do.

Below is a general guide to when these skills tend to come online. I’ve organized it by the same nine categories.

Working Memory

• Ages 2-3: holds one instruction in mind
• Ages 4-5: holds two-step directions
• Ages 6-8: can hold a few pieces of information while working on a task
• Ages 9-12: manages multi-step directions and can update information as a task changes
• Teens: adult-like capacity develops, but under stress or with competing input, it still lags

Initiation / Activation

• Ages 2-3: needs an adult to start almost everything
• Ages 4-5: can begin a preferred task independently
• Ages 6-8: can start simple, familiar tasks with a prompt or visual cue
• Ages 9-12: starts routine tasks without prompting, but non-preferred or effortful tasks still need support
• Teens: should initiate independently for familiar tasks; still can struggle with novel or high-effort tasks, often without a plan

Planning and Organizing

• Ages 2-3: no real planning, lives in the moment
• Ages 4-5: can follow a simple, adult-created plan
• Ages 6-8: begins to sequence two to three steps with guidance
• Ages 9-12: can plan a short project with support, a few days out
• Teens: can plan further ahead, but usually still needs help breaking a big task into steps

Processing Speed

• Develops steadily and gradually through childhood into the early twenties
• Less stage-based than the others – more of a slow, linear curve
• Wide individual variation is normal at every age

Attention

• Ages 2-3: sustained attention measured in minutes, easily pulled off task
• Ages 4-5: can attend to a preferred activity for ten to fifteen minutes
• Ages 6-8: can sustain attention for a full non-preferred task with structure, for short stretches
• Ages 9-12: attention holds longer, but boring or effortful tasks still require external structure
• Teens: adult-level capacity is possible, but interest and the stakes involved still impact engagement heavily

Flexible Thinking

• Ages 2-3: rigid, transitions, and changes in plan are hard
• Ages 4-5: beginning to tolerate small changes with warning
• Ages 6-8: can adjust to a change in rules or plans with some support
• Ages 9-12: can consider another person’s perspective or an alternate approach when prompted
• Teens: capable of real flexibility, but stress or big feelings can shrink it fast – true at any age

Emotional Regulation

• Ages 2-3: minimal regulation, big feelings are expressed directly
• Ages 4-5: starting to use words instead of only behavior, still needs co-regulation
• Ages 6-8: can name feelings and use a taught strategy with adult support
• Ages 9-12: can self-soothe with practiced strategies in low-stakes moments
• Teens: regulation skills are present but inconsistent – heightened by hormonal and social changes, so regression here can be expected

Self-Monitoring

• Ages 2-3: essentially none, needs external feedback for everything
• Ages 4-5: beginning to notice when something goes wrong, but not why
• Ages 6-8: can reflect on performance briefly, usually after the fact and with a prompt
• Ages 9-12: can self-check simple, familiar tasks
• Teens: real-time self-monitoring is possible but inconsistent, especially under social or emotional pressure

I have adapted these norms from the developmental executive skills research, including the work of psychologists Peg Dawson and Richard Guare (Executive Skills in Children and Adolescents). These are meant as a general guide, not an exact expectation. Normal variation is typical between kids at any age – so be careful not to compare a child too strictly to this chart.

Also, keep in mind that kids with ADHD typically develop Executive Function skills significantly later than their peers. The gap between what they can do in the moment and what we expect of them is real and based on many factors (including interest, anxiety, and real and perceived pressure).

I wrote about the research behind that statement, and what’s changed in how I talk about it, here. The short version: the old “30%, two to three years behind” figure is not as accurate as we once believed. The gap itself is real, and it’s significant – this is not just about a kid not trying hard enough.

So when you look at the chart above and wonder where your child or your student falls, remember to use the norms as a general guide. And for kids with ADHD, it’s not about lowering the bar, it’s about being realistic – and patient.
