Did you know that development of handwriting skills depends on a solid foundation of sensory processing skills?

Really, all of our motor output (both gross and fine motor) become refined and developed after sensory skills have been established. So, it’s pretty common for some kids with handwriting challenges to have underlying sensory processing issues.

Continue reading to find out more about common handwriting development struggles, when it’s time to seek OT support for handwriting challenges, and how OT can help with supporting handwriting challenges.

Keep this in mind as you read this post

Please keep in mind, I’ll be talking specifically about the act of handwriting letters.

But remember, there are pre-writing shapes and strokes (like lines, circles, triangles) that need to be mastered before writing letters. I don’t even worry about improving handwriting (actual letter writing) in children until they’re in kindergarten. I could do a whole episode on placing too high demands on preschoolers these days, but instead I’ll link a blog post I co-wrote with Susie from BusyToddler.

To be clear, I do have clients who are preschool age that I do work on visual motor skills like drawing and some letter tracing, because those skills are part of their clinical picture and things that they need support with, BUT, I would not refer a preschooler to OT solely for handwriting difficulties if that makes sense.

Like if a 4 year old was having difficulty writing their name and that was their only issue, or was grasping a pencil awkwardly, I would not refer them to OT just for this reason.

If this 4 year old also had sensory processing issues, big behaviors, meltdowns, can’t put their socks or jacket on, then yes I would work with them in OT and would also probably add some drawing and coloring/tracing skills to our work. 

So as you continue reading, remember that I’m talking about the skills leading up to handwriting development (letters and numbers) for kindergarteners or older. 

Skills that are needed for handwriting letters 

If we’re talking about the actual task of sitting down at a table, taking pen to hand and writing our name, what skills does a person need to have to successfully write the letters of their name?

Handwriting is classified as a visual-motor-integration skill, which is basically what it sounds like: integrating the visual sense and the motor senses to create an output.

But, there are many more underlying skills involved in handwriting.

Sensory processing skills and handwriting

Sensory processing skills are a huge foundational requirement to build fine motor, gross motor and even cognitive skills.

If you think of a pyramid where the top skill is handwriting, the bottom level, the foundation of the pyramid would be all of the sensory systems.

Without a refined, efficient sensory processing system, you can’t develop advanced skills. 

If your child has sensory processing difficulties related to any of those senses I mentioned (visual, tactile, proprioception, vestibular), it may be contributing to their development of handwriting skills. 

When you work with an OT on handwriting skills, don’t be surprised if they spend half the session doing an obstacle course, or going outside or doing some other fun, full body movement activity, because they’re probably working on sensory integration. 

Gross motor skills and handwriting

Did you know that gross motor development is also a requirement for the development of handwriting skills?

Without a solid gross motor foundation, fine motor skills can’t fully develop.

Gross motor skills develop before fine motor skills. Think about it, one of the first major milestones in infancy is being able to roll over, or even before that, to hold their neck up.

You would not expect a baby who can’t hold their head up or to roll over to be able to use a pincer grasp. 

They work on tummy time to develop good core and postural stability, which then allows them to have stable shoulder and trunk musculature which will later contribute to having a functional grasp pattern. 

Here are more ways gross motor development leads to fine motor and handwriting development: 

If your child has been identified to have gross motor challenges with any of those skills mentioned, an OT might offer activities like:

Use a bosu ball or inflatable exercise ball to help target postural support and endurance that can contribute to handwriting skills development.

Fine motor skills and handwriting

This is probably the skill you expected me to mention first when talking about handwriting. But actually, it’s one of the last. Why? Because you need a steady set of gross motor skills and sensory processing skills in order to refine the development of fine motor skills. 

Hopefully by now, you’re getting the picture that handwriting is not only a fine motor skill. But, of course, fine motor is a major component to handwriting. 


Cognitive skills and handwriting

Executive functioning skills are a set of higher level cognitive skills that are really necessary for so many childhood developmental tasks. And a lot of executive functioning skills are necessary for developing handwriting. For example:

And these aren’t even the actual motor parts related to writing. Can you start to see how handwriting is a complex skill? 

So if your child has difficulty with executive functioning and you’re also working on developing handwriting skills, an OT might help build executive functioning skills with games like:

There’s so much more an OT may do to build executive functioning skills to contribute towards handwriting, but they may also provide some accommodations to better support the child’s current level of executive functioning abilities like:

Remember, OTs are all about meeting the child where they’re at, providing supports so they can perform optimally at that level AND also work on building up those skills so you can hopefully decrease those supports over time.

Those were probably way more skills than you were expecting, right?

This is why when a child has difficulty with handwriting, an OT’s assessment can give you so much information on the underlying skills, and it’s why OTs are probably doing a lot of activities that don’t look like they’re working directly on handwriting.

How do I know if it’s time to seek OT for handwriting skills?

Now, I always get asked, by teachers and parents, how do you know when your child actually needs to be seen by an OT for their handwriting? So I’ll leave you with a quick checklist for you to think about.

It’s a two part checklist.

If your child displays any of the following signs (it could be just one, or many of them) 

If your child displays any of the top to grasps (fisted or digital pronate) and they’re in kindergarten, this may be time to seek support from an OT.

If any of those signs are happening, AND they are kindergarten or older

Then you would benefit from getting assessed by an OT. 

If your child is in public school, you can ask the school to assess your child, and if your child qualifies, you can get support through a school based OT. 

If your child doesn’t qualify for school based OT (they have some pretty strict requirements for qualifying children for OT), but you still want support, you can go to a private OT clinic.

I would start in a local mom’s facebook group or other local community support group and ask for private OT clinics in the area and call them up.

The person who does the intake there can usually give you the process of how to get referred by your pediatrician if needed, or any other things you may need in order to get the process rolling.

If you want help with that or any other help with OT, maybe you’re in between therapists, or are on a huge waitlist, I can help! I offer 1:1 consultations via zoom, head to

I’m an enneagram 6, so my brain is constantly moving. My OT lenses never turn off and I can’t “un-see” the sensory and other developmental skills that go in to literally every activity. I love taking what I see and breaking it down into simple terms so parents can understand what goes into their child’s behavior and skills.
