When should this dyscalculia test be used?

When should this dyscalculia test be used?

This assessment battery makes it possible to reliably detect the risk of presenting dyscalculia in children 7 years and older and adults.

We recommend using this test for anyone who you may suspect has dyscalculia. The early detection of this learning disorder can help minimize developmental difficulties and start an appropriate intervention program suitable for each profile.

This assessment battery also makes it possible to adults to understand their risk index for having dyscalculia. Many adults have lived their lived with dyscalculia and were never aware of the dysfunction. And, while they may have a normal, or even above average IQ, may have been considered poor students. Without the early detection and proper management of this learning disorder, adults with dyscalculia may have problems at work or socially.

Below are some of the most representative symptoms of dyscalculia:

Most representative symptoms
Difficulties with mathematical calculations
Difficulties recognizing mathematical symbols
Problems aligning mathematical operations
Difficulties understand spoken word problems
General symptoms

Difficulties with mathematical calculations

People with dyscalculia have trouble processing mathematical language, which makes it difficult to do mathematical processes like adding, subtracting, multiplying, and dividing.

Difficulties recognizing mathematical symbols

People with dyscalculia may confuse symbols like “+” or “-“, which may create problems when using and applying them to mathematical operations.

Problems aligning mathematical operations

It is common to have trouble changing a vertically written math problem horizontally and vice versa. With operations like multiplication or division, someone with dyscalculia may have trouble aligning the right numbers and symbols in order to get the correct answer.

Difficulties understand spoken word problems

May present difficulties remembering the information given in the word problem, which can make it very difficult, or even impossible, to correctly write and carry-out the correct mathematical operation. It is also common to have trouble differentiating relevant and irrelevant information.

General symptoms

Aside from the purely mathematical problems, people with dyscalculia may also have trouble telling time, they get lost often, and they may have poor orientation.



Description of the diagnostic criteria questionnaire

Description of the diagnostic criteria questionnaire

Dyscalculia is characterized by a series of clinical signs and symptoms. These indicators can help you understand the risk of someone having this learning disorder. This is why the first part of the assessment battery for dyscalculia (CAB-DC) is a questionnaire made of clinical questions that have been adapted to the diagnostic criteria and symptoms of dyscalculia for each age range.

The questions presented here are similar to those that can be found in a diagnostic manual, clinical questionnaire, or evaluation scales. However, they have been simplified to be easily understood by almost any user.

Diagnostic criteria for children 7-18 years-old

Made up of a series of simple questions that should be answered by a parent or the professional in charge of the assessment. The questionnaire will cover the following domains: Mathematical language (comprehension of the mathematical symptoms, their meaning, and representation), Mathematical reasoning (numeric thinking, problem solving, logic, etc.), Social relationships (caused by frustration and frustration that may these math problems may have caused), Learning and development (dyscalculia is related to different familiar and developmental factors).

Diagnostic criteria for adults

A series of simple questions that can be completed by the professional in charge of the evaluation or by the person taking the test. The questionnaire will cover the following domains: Mathematical language (comprehension of mathematical symptoms, their meaning, and representation), Mathematical reasoning (numeric thinking, problem solving, logic, etc.), Academic history (due to the relation between dyscalculia and academic failure), Professional and social areas (difficulties with the relationship of calculations and daily life).

Description of the battery to evaluate the neuropsychological factors affected by dyscalculia

Description of the battery to evaluate the neuropsychological factors affected by dyscalculia

The presence of alteration in some specific cognitive skills may be indicators of dyscalculia. A general profile of the cognitive skills may indicate how severe the alterations are. Problems with calculations, academic difficulty, and social and emotional problems may be caused by deficits in different cognitive skills. These are the domains and cognitive skills evaluated in the dyscalculia test (CAB-DC):

Evaluated Cognitive Domains
Cognitive Abilities


Ability to filter distractions and focus on relevant information.


8.0% above average

Divided Attention

Divided attention and dyscalculia. Divided attention is the ability to pay attention to more than one stimuli or activity at the same time. People with alterations in divided attention use more cognitive resources when carrying-out two or more tasks at a time, which would make it difficult to listen to a teacher and copy a math problem.

492Your Score


Focused Attention

Focused attention and dyscalculia. Focused attention is the ability to focus attention on a target stimulus, regardless of how long. We use focused attention in class or doing homework. When distracted, it’s possible to miss important information, which makes it more difficult to correctly complete math equations.

747Your Score



Ability to retain or manipulate new information and recover memories from the past.


7.9% above average

Short-Term Memory

Short-term memory and dyscalculia. People with dyscalculia may have alterations in this cognitive skill. Short-term memory is the ability to hold onto a little bit of information for a short period of time, like when you have to remember how much you calculated for a tip at a restaurant. A problem with short-term memory may impede the ability to correctly solve math problems.

730Your Score


Working Memory

Working memory and dyscalculia. It is important to keep in mind that an alteration in working memory may be a strong indicator of dyscalculia. Working memory is the ability to retain and use the necessary information to complete complex cognitive tasks, like mathematic operations. Poor working memory may make it difficult to do both complex and simple math problems.

561Your Score



Ability to efficiently carry-out precise and organized movements.


7.8% above average

Response Time

Reaction time and dyscalculia. Reaction time is the ability to perceive, process, and respond to a simple stimulus, like quickly and efficiently solving a simple math equation. People with slow response time often have trouble easily and fluidly completing math problems.

562Your Score



Ability to interpret the stimuli from one's surroundings.


8.3% above average


Recognition and dyscalculia. Recognition is the brain’s ability to identify a stimulus that it had perceived previously. This makes it possible to compare present information with the information stored in one’s memory. Poor recognition may make it difficult to recover information from a math problem or remember a formula.

550Your Score



Ability to efficiently use (organize, relate, etc.) acquired information.


8.1% above average


Planning and dyscalculia. Planning is the ability to mentally organize the best day to reach a specific future goal, like when you need to organize how to solve a math problem as easily as possible. People with alterations in planning may have trouble solving complex problems or calculations.

728Your Score


Processing Speed

Cognitive processing speed and dyscalculia. Processing speed is the ability to process information quickly and automatically. People who have allegations in processing speed may take longer to understand and complete math problems. Slow auditory and verbal processing may cause problems when decoding numbers, letters, words, and sentences.

675Your Score



Ability to understand and express verbal information (spoken, written, etc.).

Evaluation tasks

Evaluation tasks

This multi-dimensional scientific resource uses multiple evaluation tasks. Here you can see examples:

Decoding Test VIPER-NAM

This evaluation task integrates notions of the classic Korkman, Kirk and Kemp test of 1998 (NEPSY). It measures the naming capacity, response time and processing speed, measuring the number of cognitive resources that the user allocates to the exercise of decoding, recognizing and understanding stimuli in an efficient way.

Identification Test COM-NAM

The COM-NAM Identification test is based on the classic NEPSY and TOMM tests. With this test, the level of channeling and classification of stimuli in memory is observed. In addition, it allows the ability to observe how the user detects and reacts as fast as possible.

Sequencing Test WOM-ASM

The Sequencing Test WOM-ASM was based on Conners' classic test (CPT) and the Wecshler Memory Scale (WMS) test of direct and indirect digits. Using these tests, we are able to observe the temporary storage capacity and, above all, the capacity to manipulate information to perform higher cognitive tasks, such as language comprehension or reasoning.

Concentration Test VISMEN-PLAN

This evaluation task is inspired by the Wechsler Memory Scale (WMS) direct and indirect digits test, the classic Memory Malingering Test (TOMM) and the classic Tower of London Test (TOL), allowing to measure planning capacity, visual memory, short-term memory, response time, working memory and processing speed, among others.

Dyscalculia and The Brain

Dyscalculia and The Brain

Dyscalculia makes it difficult to understand and carry-out math operations. Neuroimaging studies have consistently shown the close relationship between dyscalculia and certain brain areas. Some of the most affect brain areas in dyscalculia are:

1 Intraparietal ridge

Recent studies have shown that the intraparietal ridge, especially in the right hemisphere, is one of the brain structures that shows anomalies in people with dyscalculia. This right intraparietal ridge is crucial for the correct processing of numeric information.

2 Frontal lobe

The frontal lobe, especially the prefrontal dorsolateral portion, is closely related to executive functions, like planning or working memory, which is both necessary to carry out calculations and solve mathematical problems. Dyscalculia may also cause an alteration in the cognitive abilities related to this area of the brain.

3 Superior Parietal Lobe

The right parietal lobe that interprets spatial information, while the left parietal lobe understand numbers, the manipulation of different objects, and writing.

4 Left Angular Gyrus

In charge of the verbal use of numbers.

It would be much more comfortable to be able to take the test right from my professional account. The kids I work with sometimes have trouble logging in and have other problems that I can fix for them.

Child Psychologist


I've used the old platform and have now been using the new one. The format has really improved and I've noticed a lot less bugs.

Mountain View Psych


The reports have really helped make diagnoses.



I work with families and children and have seen this to be a great test for my patients who often have trouble paying attention for long periods of time

Rachel T


It's a test that I would use along with a consultation, but wouldn't be able to use it on its own to replace other tests



We had some trouble starting the test and my daughter got bored half way through. She's used to using the ipad so working on the computer with a mouse was an added challenge that I don't know if the scores took into account.



My son took this (just under 7 years-old) because I thought he might have dyscalculia. It took him about 25 minutes and I had to be nearby to help answer questions when he didn't understand. We got a 15 page report and some of it was too technical. I'm bringing it to the doctor next time we go.



Excellent tool and descriptive feedback.



helpful to see why my son has problem with math we'll bring the report next time we see the teacher
