At first, you might just chalk it up to classic kid stuff. Daydreaming. Dilly-dallying. Taking forever to get out the door and off to school. But as time goes by, you start to realize it isn’t just a morning thing. Homework takes forever, even when your child understands it. They know the answer but pause so long before saying it. And multi-step directions? Forget about it. “Brush your teeth, grab your backpack and meet me by the door” might as well be a riddle in another language. If this sounds all too familiar, your child may have slow processing speed.

What are the Signs of Slow Processing Speed?
In simple terms, slow processing speed means a child takes longer than their peers to take in information, make sense of it and respond. It can show up in all kinds of ways:
• Problems recalling and following verbal directions
• Taking a long time to write things down
• Trouble getting things done (getting dressed, doing homework, cleaning their room)
• Information learned is quickly lost
• Difficulty keeping up with conversations; gets lost easily in social interactions
• Struggling to finish tests or assignments on time
• Does not join in with class discussions
• Finds it hard to tune out distractions
• Becomes anxious, frustrated or tired as the day goes on
• Getting overwhelmed with multi-step directions
• Answering questions more slowly—even when they know the answer
Rebekah McPherson is a speech language pathologist at Key School and Training Center, a school in Fort Worth that serves students with learning differences, and a proud mom to Mitchell, a 7th grader there. McPherson says that she and her husband noticed very early on, when Mitchell was 4 or 5 years old, that he was not picking up on counting and the alphabet.
“Certain things weren’t coming naturally like writing his name. My background is in education, education technology and communication. I’ve been a teacher for 23 years, so I was aware of what kids should be able to do at a certain age,” says McPherson.
When Mitchell was in kindergarten, his teacher suggested to McPherson that he be evaluated. She says, “We sought an outside evaluation after speaking with Mitchell’s pediatrician … We found out he was dyslexic, and he also had ADHD in addition to slow processing speed.”

Can Slow Processing Speed Co-Occur with Other Learning Difficulties?
Mitchell’s situation isn’t uncommon. Slow processing speed often shows up alongside other learning differences, and it’s not uncommon for kids to experience more than one area of difficulty at the same time. For example, ADHD frequently co-occurs with slow processing speed. While ADHD is more about attention, focus and self-regulation, the added challenge of needing more time to take in or respond to information can complicate things even further. People with ADHD might struggle to get started on tasks or finish them quickly enough, especially in environments that demand fast thinking or rapid responses.
Dyslexia is another common co-occurring condition. Since dyslexia affects reading and language processing, slow processing speed can make decoding words or understanding text more time-consuming. Dysgraphia, which impacts writing skills, can also overlap—making it harder to get thoughts onto paper quickly or clearly.

In some cases, slow processing speed may appear alongside anxiety, especially if the pressure to perform quickly leads to stress or worry. Recognizing these combinations can help tailor support strategies that address the full picture, not just one piece of it.
How is Slow Processing Speed Diagnosed?
To find out if slow processing speed is what’s really going on, a formal evaluation by a psychologist or other qualified professional is the gold standard. This isn’t your average pop quiz. It includes a full battery of tests that measure cognitive, academic and executive functioning.
The process for diagnosing slow processing speed can involve different types of assessment. Occupational therapist Kyle Welch practices at Little Red Wagon Pediatric Therapy in Fort Worth, which offers specialized services (speech and occupational) for kids in a clinical setting.
He says, “A psycho evaluation may be done by a school psychologist. There could be a clinical diagnosis where experts are examining cognitive or sensory delay. An analysis can be done of the child’s academic achievement and/or questionnaires completed by a family member or teacher.”
Part of the evaluation process includes timed tests. These performance tasks help reveal how efficiently your child’s brain is working when the clock is ticking. In addition, the assessor will screen for other possible culprits such as ADHD, learning differences (like dyslexia), or anxiety, to make sure slow processing speed isn’t a symptom of something else entirely.

How Does Slow Processing Speed Impact Learning & Social Development?
Parents, try to imagine keeping up in a game where everyone gets the rules before you’ve even opened the box. That’s kind of what school can feel like for a kid with slow processing speed.
They know the answer but didn’t get it out fast enough before the teacher moved on. They’re doing their best to write the sentence but can’t write as quickly as the other kids. They’re spending so much energy just listening and keeping up that by the end of the day, they feel destined to fail. It can lead to frustration, low confidence, and that heartbreaking “I’m not good at school” feeling—even when they are.
Carson James Boswell is an educational diagnostician at the Key School. She explains that there are many classroom tasks that can be affected by slow processing speed.
“Reading difficulties can interfere with comprehension, which can mean the child has to take the time to reread the content. Writing difficulties may limit their output because of time factors. Language difficulties can make it hard to retrieve information, and then they can’t get thoughts out as quickly. In subjects like math, there might be difficulties with automatic computation,” she says.
McPherson says it’s because of Mitchell’s placement in the Key School that his academic experience hasn’t been negatively affected. “The school is made for those with learning differences. It’s already built into the day-to-day that students have more ‘helps,’ so it is not viewed as anything extra. Audio books…everybody gets them. Text to speech technology…everybody gets it. Because Mitchell has always been in a specialized school, it is such a better situation. He is thriving.”
For kids with slow processing speed, social interactions and emotional well-being can be interrupted. It can be tough for your child to keep up. They might miss the joke, not know when to jump in, or respond a beat too late. And sadly, that can make them feel left out, or like they don’t quite fit.
“As children with slow processing speed get older, beyond kindergarten and first grade, they may experience frustration, embarrassment, and anxiety. That’s not just in the classroom; it can be while they are playing school sports that require rapid skill execution,” says Welch.
If your child is exhibiting slow processing speed and in public school, they may require additional support to thrive academically and socially. To ensure equitable access to education, these students may benefit from a customized plan that can provide targeted accommodations or modifications.
Are Kids with Slow Processing Speed Eligible for an IEP or 504 Plan?
“Once there is a formal diagnosis of slow processing speed, a 504 plan is established. An IEP (Individualized Education Program) will also be implemented. This doesn’t mean the student will have to be in special education,” Welch says.
An IEP is like a custom-built support system for your child at school. It includes all the bells and whistles—specialized instruction, therapies, accommodations, maybe even a modified curriculum. It’s detailed, written down, and legally binding. A 504 plan, on the other hand, is more like a helpful nudge to level the playing field. It’s for students who don’t need specialized instruction but still face challenges because of a learning difference. This plan helps remove barriers so they can learn alongside their peers.
Certain accommodations and modifications can be extremely effective in supporting slow processing speed in the classroom. Welch says, “Extra time is No. 1. I am a big proponent of the use of technology to eliminate some of these barriers. Text to speech, for one, is great because the student doesn’t have to focus on note taking but can instead just listen and absorb the information. Other modifications may include a reduced workload or breaking down the instructions for tasks a little bit more.”
Boswell agrees that a reduced workload can be beneficial for these students in most situations. She says, “If the child can show that they’ve mastered the subject in five problems instead of 10, why not do that?”

How Can Parents Support a Child with Slow Processing Speed?
“At home, it’s helpful to make a visual schedule. Be up front about time and be consistent by establishing routines. Parents can limit distractions when their child is doing homework and should consider implementing breaks and dividing homework into smaller segments to avoid fatigue,” Boswell says. “For most of these kids, their brains are working in overdrive. Another helpful tip is to set microdeadlines. For instance, if you have a big deadline on a certain date, come up with smaller deadlines along the way to help them stay on track.”
Welch says that some therapeutic interventions may help improve processing speed over time. “Repetitive practice helps create muscle memory. It’s important when having a child do a task that they are doing it the exact same way every time. An example of this is teaching a child to tie their shoes. You don’t want to show them three different ways to do it. There needs to be consistency. It’s also important to take the time factor off the table so that the child doesn’t feel rushed,” he says.
The biggest takeaway that McPherson wants people to have is that just because you have slow processing speed, it doesn’t mean you’re not smart. She says, “Mitchell understands that. He feels confident. He says, ‘I know I am a slow reader, but I have a really good vocabulary.’ He’s aware of his weaknesses, but he’s also aware of his strengths.”
