At a recent children’s book fair, many parents came to us with the same questions:
“My child is bright — so why don’t their results show it?” “They pick things up quickly, but consistently fall short of their own potential.”
These are not signs of limited potential. They are often signs that executive function needs support.
What Executive Function Actually Does
The Harvard Center on the Developing Child describes executive function as the set of mental skills that allow us to plan, focus attention, remember instructions, and manage multiple tasks at once. Think of it as an air traffic control system — one that must coordinate the safe landing and take-off of multiple aircraft simultaneously, across multiple runways, in real time.
Most of the tasks children face every day require several executive functions working together. Three are especially critical:
Working Memory — Holding and using information while in the middle of a task. For a child sitting in class, this means following what the teacher is saying while simultaneously processing what is written on the board.
Inhibitory Control — The ability to pause before acting and resist competing impulses. For a child coming home from school, this is the difference between reaching for a phone and sitting down to homework first.
Cognitive Flexibility — The ability to shift thinking when circumstances change or a first approach is not working. For a child trying to study, this is what helps them try a different strategy when the material simply will not stick.
Why It Cannot Be Left to Chance
A longitudinal study from the University of Illinois at Chicago found a meaningful positive relationship between children’s executive function in primary school and their academic performance eight years later in secondary school. Executive function, however, does not strengthen automatically with age. Without appropriate guidance and training, the gap between a child’s potential and their performance can quietly widen over time.
The good news is that executive function is not fixed. With the right environment, consistent practice, and support at the right time, it can be meaningfully developed — giving every child a better chance to become who they are capable of being.
