Where to Go for a Dyscalculia Evaluation on Long Island
If numbers, math facts, or everyday tasks like telling time or handling money have always felt disproportionately hard, a comprehensive private evaluation is the clearest way to find out whether dyscalculia is the reason. Coast Psychology, located in Oyster Bay, NY, provides comprehensive dyscalculia evaluations for children, teens, and adults across Nassau County, Long Island, and the greater New York City area.
What Is Dyscalculia?
Dyscalculia is the term for what the DSM-5 classifies under Specific Learning Disorder with impairment in mathematics. It can affect number sense, memorization of arithmetic facts, accurate and fluent calculation, and mathematical reasoning.
Dyscalculia affects an estimated 3% to 7% of people globally, even though it's far less widely recognized than other learning disabilities, such as dyslexia. It isn't about 'not being a math person.' It's a persistent, significant difficulty that's disproportionate to a person's overall ability and to the instruction they've received.
Signs of Dyscalculia by Age
Preschool & Kindergarten
Trouble learning to count reliably or in the correct order
Difficulty connecting a number, like 5, to an actual quantity of objects
Trouble recognizing numerals and basic math symbols
Difficulty with concepts like 'more than,' 'less than,' or 'first, second, third'
Elementary School (Ages 6–9+)
Relying on finger-counting long after peers have moved past it
Trouble recognizing small quantities at a glance, without counting one by one
Persistent difficulty memorizing basic math facts, even with repeated practice
Not grasping that an equation works the same way rearranged (for example, that 8 = 7 + 1 is the same fact as 1 + 7 = 8)
Getting lost partway through multi-step problems
Teens & Adults
Difficulty with mental math that peers seem to do easily
Struggling with word problems or multi-step problem solving
Trouble with time, measurement, or estimating quantities
Difficulty with everyday math like managing money, tipping, or following a recipe
Math anxiety that developed after years of struggle, rather than being the original cause of it
Why a Comprehensive Evaluation Matters
A comprehensive evaluation is what distinguishes true dyscalculia from math anxiety, gaps left by missed or inconsistent instruction, careless errors driven by attention difficulties, or a broader language-based learning disorder that also makes word problems harder. Each of those has a very different solution, though they can look similar from the outside.

Where to Go for a Dyscalculia Evaluation Near You
Coast Psychology is based in a National Historic Landmark Victorian building in downtown Oyster Bay, NY (11771), and evaluates families across Nassau County, Long Island, and the greater New York City area, including Queens, Manhattan, and Brooklyn.
Because dyscalculia is less commonly discussed than dyslexia, it's often the last learning disability parents think to ask about and it can also be missed by a school evaluation. Our article on private vs. school evaluations explains why that gap exists and how a private evaluation fills it.
Frequently Asked Questions
Is dyscalculia just being bad at math?
No. Plenty of people find math challenging without having dyscalculia. Dyscalculia is a specific, persistent, and disproportionate difficulty with number sense and mathematical reasoning that doesn't resolve with typical instruction and practice.
Can dyscalculia be diagnosed in a young child?
Reliable diagnosis usually comes once formal math instruction has begun and intervention has been trialed.
Does dyscalculia affect anything besides math class?
It's centered on mathematics, but it can affect related everyday skills like managing time or money. Dyscalculia also frequently co-occurs with dyslexia or ADHD, which is part of why a comprehensive evaluation matters more than a narrow math screener.
What actually helps a child with dyscalculia?
Targeted, often multisensory math intervention paired with appropriate accommodations tends to make the biggest difference and both should be informed directly by evaluation results, not guesswork.
Will my child's school evaluation catch dyscalculia?
Not always. School evaluations are structured around eligibility for services, and math-specific patterns like dyscalculia can be under-identified as a result. Our article on private vs. school evaluations explains this distinction in more detail.
