A learning disability is an impairment in reading, writing, and/or math not explained by overall intellectual functioning.

The cause is neurological—it is not a reflection of motivation or laziness and cannot be overcome by sheer willpower.

The only way a learning disability can be diagnosed is by neuropsychological testing or neuropsychological assessment, also called psychoeducational testing. Cognitive Assessment Group offers learning disability and dyslexia testing in NYC and Chicago to discover and evaluate neuropsychological impairments that may be affecting you or a loved one.

Neuropsychological testing is critically necessary to diagnose a variety of learning disorders including dyslexia, dyscalculia, non-verbal learning disability, dyspraxia (apraxia), dyspgraphia, central auditory processing disorder, and a specific learning disorder involving reading, writing or math. We also evaluate for intellectual disability when that issue arises.

It’s important for you to have an evaluation done correctly. There are many types of tests for a learning disability, and some more accurate or appropriate than others. Be sure your evaluation is thorough and uses the most appropriate tests for you. At the Cognitive Assessment Group, we have evaluated thousands of persons for learning disabilities, including dyslexia, in NYC and Chicago. Our specialists know which tests are most appropriate for you.

Workplace, Test or School Accommodations

We provide extensive written reports for testing agencies (e.g. ACT, SAT, GRE, MCAT, LSAT, GMAT, USMLE and others) as well as schools, boards of education or employers to assist with accommodations if warranted. We offer fast turnaround time for reports if a deadline is fast approaching. Persons with a diagnosis of ADD, ADHD, learning disability or a cognitive disorder may qualify for extended time on a school or standardized examination such as testing in a quiet room or having a reader or scribe.

Testing agencies are very strict in what tests they require to be administered and reported. It is critical for you to be evaluated by someone who has experience in testing persons for accommodations on standardized tests. If your scores are reported differently than the agency requires, or the required tests are not administered, your application will be rejected. At the Cognitive Assessment Group, our reports are routinely accepted for test accommodations and we know the specific requirements for each test agency. Call us today for an appointment and have your NYC dyslexia testing or other learning disability assessment done correctly to avoid having to be re-tested later to satisfy the requirements of your test agency.

The Americans with Disabilities Act requires that accommodations be made for persons with a disability including cognitive, emotional and learning disabilities. Examples include Disorders of Reading, Writing or Mathematics, Attention Deficit Disorder with or without hyperactivity, nonverbal learning disorder (Learning Disorder NOS), Test Anxiety (termed a Specific Phobia), and other cognitive disorders. Accommodations can take the form of extra time during standardized tests or classroom assignments, a quiet and distraction free environment at work or in a standardized testing situation, and in some cases, a note taker or scribe in the classroom.
