What the check measures
4 tasks, about 20 minutes. Each task starts with a short practice.
- 1 · Dot comparison
Dots
Two groups of dots appear for a moment. Pick the group with more.
- 2 · Magnitude comparison
Numbers
Two numbers appear. Pick the larger one.
- 3 · Arithmetic verification
Sums
A simple sum appears with an answer. Say whether the answer is right.
- 4 · Number line
Line
Mark where a number belongs on a line.
In research terms the four tasks are dot comparison (non-symbolic magnitude comparison), symbolic magnitude comparison, arithmetic verification and number line estimation, standard paradigms in studies of number skills.
Before the tasks: six questions about everyday numbers and how numbers make you feel, about 2 minutes.
What you get
The check is free
- A profile of number sense, calculation and number symbols, each shown as typical range, below typical or clearly below.
- Your profile right after the last task.
- The first task is free. A free account lets you continue and keeps your profile on any device.
Dyscalculia report
- What your number tasks show, in plain words.
- Practical adjustments for money, work and study.
- Offered on your profile once you finish the check.

Who it is for
- Adults who have always found numbers harder than expected: money, time, measurements or mental arithmetic.
- Anyone who wants a record of their number skills before talking to a clinician, tutor or employer.
A check, not a diagnosis
The check shows how you did on four number tasks. It cannot diagnose or rule out dyscalculia. If your results concern you, discuss them with a clinician or an educational psychologist.
Questions
What does the check cost?
Nothing. The check is free and so is your profile. The report is optional.
Do I need an account?
Yes, after the first task. Create a free account to continue; it keeps your results.
Is this a dyscalculia diagnosis?
No. Only a qualified professional can diagnose dyscalculia. The check gives you indicators to bring to that conversation.
Can I take it on my phone?
Yes. Tap the answers on a phone, or use the arrow keys on a computer.
Do I have dyscalculia?
An online test cannot tell you. The check shows how you did on four number tasks and how you answered six questions about everyday numbers, as indicators. A qualified professional, such as an educational psychologist, can assess whether dyscalculia explains what you notice.
How do adults get tested for dyscalculia?
A qualified professional with experience in adult maths difficulties, such as an educational psychologist or a specialist assessor, looks at your history, standardized maths tests, how the difficulty affects daily life and other possible explanations. Concrete everyday examples, and your check results, can help that conversation.

What dyscalculia is and how adults are diagnosed
ICD-11 describes developmental learning disorder with impairment in mathematics as persistent difficulty learning academic skills involving number, calculation, or mathematical reasoning. Difficulties begin during development, may persist into adulthood, and can cause meaningful impairment in academic, occupational, or daily functioning. Prevalence estimates vary with the criteria and population studied; the 2019 clinical guideline cited below reports prevalence estimates of approximately 3–7%.
Assessment considers developmental and educational history, the opportunity to learn, standardized achievement, functional impact, and conditions that could better explain the difficulty. In adults, a professional may also examine how number difficulties have persisted and affect current life. No single browser task is sufficient.
A careful boundary. Education, language, attention, anxiety, sensory factors, device conditions, and the testing environment can all affect number-task performance. A browser task cannot determine why a result looks the way it does.
Signs considered in an adult assessment
Assessment looks for persistent difficulty with mathematical learning and use, meaningful functional impact, developmental onset, and alternative explanations. Supported areas include:
- Money. Difficulty applying number skills during simple money transactions.
- Time and measurement. Difficulty applying number skills to time, quantities, units, or measurements in daily activities.
- Study and work choices. Adults may report that number difficulties influenced academic or occupational choices.
These examples are educational, not a self-diagnosis. A qualified professional evaluates the full pattern and context.
How the profile is worked out
Number Line and Dot Comparison are compared with published data. Magnitude Comparison and Arithmetic Verification are read against fixed, provisional cutoffs, as indicators. None of these tasks diagnoses or rules out dyscalculia.
