The Skills That Will Matter Most: How Montessori Classrooms Support Executive Functioning
Think about the jobs that existed ten years ago that don’t exist today. Now think about the jobs your child might hold that don’t exist yet. The world is changing faster than most school curriculums can keep up with and that raises a real question for every parent: what are we actually preparing our children for?
As educators it is imperative for us to look towards the future to ensure that our children have the skills to think, build, and lead. Fortunately, Dr. Montessori created a model over 100 years ago that provides a strong foundation for executive functioning skills that will help our children do just that.
The answer isn’t solely in academics or test scores. It’s something deeper: the ability to think flexibly, manage yourself, solve problems, and keep going when things get hard. These are what researchers call executive functioning skills, and they may be the most important thing a child can develop.
What Are Executive Functioning Skills?
Executive functioning refers to a set of cognitive processes, primarily working memory, inhibitory control, and cognitive flexibility, that help us coordinate thoughts and actions to reach our goals.[1] These skills also support the ability to plan, organize, emotionally regulate, and take initiative.
Unlike specific facts or formulas, these skills transfer. Research has repeatedly shown that executive functioning predicts educational outcomes above and beyond measures of intelligence or prior academic ability.[2] A child who can regulate their frustration, think through a problem from multiple angles, and manage their time doesn’t just do well in school — they’re equipped for life’s challenges and opportunities.
Why Starting Early Matters
Executive functioning skills develop rapidly in early childhood and continue maturing throughout adolescence.[3] The brain’s prefrontal cortex — the hub of executive functioning — is highly responsive to environment and experience during these years, which means the conditions we create for children genuinely matter.
Notably, research has found that working memory at age 5 is a stronger predictor of later academic performance than IQ.[4] This looks different at each level here at Greenspring. For instance, toddlers begin to count and set out plates for their peers. In Children’s House, students are building on their foundation, following complex, multi-step sequences that require them to retain detailed information. In Elementary and Adolescence, our students manage their own work journals, keeping track of where they excel and where they have room for growth. They are all, in very real ways, building new neural pathways and skills that will last a lifetime.
Scaffolding these skills early doesn’t mean pushing children before they are ready — it means creating the right environments with meaningful choice, appropriate challenges, and the freedom to learn from their mistakes.
How Montessori Builds Executive Functioning Skills
A study published in Science found that children in Montessori programs showed significantly greater gains in executive function, reading, math, vocabulary, and social problem-solving compared to peers in conventional schools.[5] A 2023 systematic review of 32 rigorous studies confirmed these findings, reporting that Montessori students showed higher executive functioning than peers in traditional schools.[6] Most recently, a national randomized controlled trial of 588 children across 24 public Montessori programs found that Montessori students scored significantly higher in executive function, reading, memory, and social understanding by the end of kindergarten.[7]
Our Guides thoughtfully look at Dr. Montessori’s curriculum to ensure that children at all levels are developing executive functioning skills such as:
- Working Memory
- Cognitive Flexibility
- Sustained Attention
- Inhibitory Control
- Task Initiation
- Planning
- Prioritizing
- Organization
- Time Management
- Self- awareness
- Emotional Regulation
This is no small undertaking! A Young Toddler learning to return a material to its place is practicing order and self-regulation. A Lower Elementary student choosing how to spend their work cycle is practicing planning and prioritization. An Adolescent navigating a multi-week research project is practicing every executive functioning skill at once. The work looks different at every level — but the intentionality is the same.
Preparing Children for a World We Can’t Predict
Researchers have identified creativity, flexibility, self-control, and discipline as the four qualities children will most need to thrive in the future — all of which are rooted in strong executive functioning.[8] We can’t know exactly what challenges our students will face in 10, 20, or 30 years, but we can give them the inner tools to meet those challenges with confidence.
