Processing Speed
Processing speed evaluations for children and teens
Some children know the material but simply need more time to work with it. When processing speed is slower than expected, capable students can look unprepared — especially on timed work.

What it actually is
Speed is not the same as ability
Processing speed describes how quickly a child takes in information, works with it, and responds. It says nothing about how much they understand or how intelligent they are — only how long the mental steps take.
That distinction matters enormously at school, because so much of what a child is graded on is timed: tests with a clock, notes taken at the pace of a lecture, and assignments expected to be finished within a set period.
A student with strong reasoning and slower processing can look inconsistent — brilliant in discussion, disappointing on the test.
What to look for
Signs that processing speed may be part of the picture
- •Consistently the last to finish, despite understanding the work
- •Tests left incomplete even when the answered portions are correct
- •Notes that fall behind and end up with gaps
- •Needing extra time to respond to questions in conversation or in class
- •Performing far better on untimed work than on timed work
- •Fatigue and frustration that build across the school day
The pattern to notice is a gap between what your child knows and what they can show within a time limit.
The most common misread
Slower is often mistaken for less capable
When a bright child works slowly, adults tend to reach for explanations like carelessness, distraction, or lack of preparation. Testing separates speed from ability directly — and that separation often changes how everyone, including the child, understands their years of effort.
What you receive
What the evaluation gives you
Processing speed is measured directly and interpreted alongside the other abilities it interacts with.
More than one number
What we assess alongside processing speed
Processing speed rarely operates alone, so the evaluation examines the abilities that interact with it.
Testing is chosen around your child's profile and the specific timing difficulties you have been seeing — never a fixed package.
The process
How the evaluation works
Consultation
We discuss where the timing problem shows up: tests, homework, note-taking, or all three.
Records review
We examine work samples and past testing for the gap between timed and untimed performance.
Testing
Two to three sessions measuring processing speed alongside reasoning, attention, and fine-motor skills.
Interpretation
Dr. Duhning compares speed against your child's other abilities to quantify the discrepancy.
Report
We meet to review what the findings mean for timed testing and everyday workload.
Roadmap
You receive documentation supporting extended time, plus practical classroom adjustments.

Processing speed evaluations
Does slower processing speed mean lower intelligence?
No. Processing speed and reasoning ability are separate, and many children have strong reasoning alongside slower processing. That combination is precisely what makes the pattern so confusing at school: the child clearly understands the material but cannot demonstrate it within the time allowed.
Will my child qualify for extended time?
Where testing shows processing speed meaningfully below a child's other abilities, extended time is a common and well-supported accommodation. The evaluation provides the objective data and written documentation schools and testing boards generally require, though each school and testing board applies its own criteria.
Can processing speed improve?
Speed itself tends to be relatively stable, but its impact can change considerably. Building automaticity in core skills, reducing unnecessary demands, and using well-matched accommodations often make a substantial practical difference — which is why identifying it early matters.
Could something else be causing the slowness?
Yes, and separating those possibilities is a core purpose of the evaluation. Attention difficulties, anxiety, perfectionism, weak fine-motor skills, and underlying learning disabilities can all slow a child down. Testing identifies which factors are involved and how they interact.
Will this affect college admissions or standardized testing?
It can work in your favor. Testing boards have formal processes for requesting accommodations such as extended time, and they generally require documentation from a qualified evaluator that includes specific testing data. Requests are strongest when there is a documented history, so evaluating well before test dates is worthwhile.
My child's IQ testing came back fine. Why look at this separately?
Because a full-scale score can hide the pattern. Processing speed is one component of most cognitive assessments, and a strong reasoning score can average out a much weaker speed score — producing a “fine” overall number that conceals precisely the difficulty affecting your child every day. What matters is the profile, not the single figure.
Is this the right step?
Consider an evaluation when
Processing speed is worth measuring directly whenever there is a persistent gap between what your child understands and what they can produce in the time available.
- ✓Your child performs noticeably better on untimed work
- ✓Tests come back incomplete rather than incorrect
- ✓Homework takes far longer than teachers estimate
- ✓You are being told your child “just needs to focus” without further explanation
- ✓Standardized testing or college planning is approaching
Does your child know more than the clock lets them show?
An evaluation separates speed from ability — and supports the accommodations that follow.
