Learning Disabilities Assessment: Identifying Specific Learning Challenges

Evidence-based assessments that identify significantly uneven patterns of processing information that make it especially hard to complete what is expected in an otherwise normally intelligent person. This could include singular or multiple areas (e.g., language, visual processing, memory, reading/dyslexia, writing/dysgraphia, math, etc.), which is why thorough testing is warranted.

What Is a Learning Disabilities Assessment?

A learning disabilities assessment is a comprehensive psychoeducational evaluation that identifies specific learning differences affecting reading (dyslexia), writing (dysgraphia), mathematics (dyscalculia), or other academic skills. We measure cognitive abilities, academic achievement, and information processing to understand why learning is harder in certain areas.

Our assessments follow Ontario guidelines and use standardized tools recognized by school boards for Individual Education Plan (IEP) development.

It is important to understand how a formal psychoeducational assessment differs from what happens at school. In Ontario, schools can observe learning difficulties and provide informal classroom supports. However, a formal identification of a learning disability as an exceptionality requires a psychoeducational assessment by a registered psychologist or psychological associate. This assessment is needed for a student to go through the Identification, Placement, and Review Committee (IPRC) process, which formally identifies exceptionalities and determines placement in appropriate programs.

A learning disability is not an intellectual disability. People with learning disabilities typically have average or above-average intelligence. A learning disability means there is a specific gap between a person’s cognitive abilities and their achievement in one or more academic areas. This gap is not caused by lack of effort, poor instruction, or low intelligence. It reflects a difference in how the brain processes certain types of information.

Signs You May Need Assessment

  • Reading significantly below grade level despite adequate instruction
  • Difficulty with spelling, written expression, or organizing thoughts on paper
  • Struggles with math concepts, number sense, or math facts
  • Slow processing speed affecting ability to complete work on time
  • Inconsistency between obvious intelligence and academic performance
  • Avoidance of reading, writing, or homework
  • Difficulty retaining information despite repeated exposure
  • Frustration, anxiety, or low self-esteem related to school performance

Types of Learning Disabilities

Learning disabilities are specific and affect distinct areas of academic performance. Here are the most common types we assess.

Dyslexia (reading disability). Dyslexia affects reading accuracy, reading fluency, and reading comprehension. People with dyslexia often have difficulty decoding words, recognizing sight words, and connecting sounds to letters (phonological processing). Dyslexia is the most common learning disability, affecting an estimated 5 to 10 percent of the population.

Dyscalculia (math disability). Dyscalculia affects number sense, math facts, calculation, and mathematical reasoning. People with dyscalculia may have difficulty understanding quantity, memorizing math facts, telling time, or understanding spatial relationships in math. Dyscalculia is less widely recognized than dyslexia but affects a similar percentage of people.

Dysgraphia (writing disability). Dysgraphia affects handwriting, spelling, and the ability to organize thoughts on paper. People with dysgraphia may produce illegible handwriting, have difficulty with fine motor coordination for writing, or struggle to translate their ideas into written form despite having strong verbal expression.

Other specific learning differences. Some people have specific difficulties with auditory processing, visual-motor integration, or processing speed that affect learning but do not fit neatly into one category. Our comprehensive assessment identifies the specific nature of each person's learning profile.

Memory & Cognitive Processing

Memory and processing speed are fundamental to learning. Our psychoeducational assessment includes detailed evaluation of these cognitive processes because they often underlie or contribute to specific learning disabilities.

Working memory. Working memory is the ability to hold information in mind while using it, such as remembering a phone number long enough to dial it or keeping track of multiple steps in a math problem. Weaknesses in working memory are common in students with learning disabilities and ADHD, and can affect reading comprehension, math problem-solving, and written expression.

Long-term retrieval. Some students can learn information but have difficulty retrieving it efficiently. This can look like "forgetting" material that was previously learned, slow recall of math facts, or difficulty with spelling despite adequate instruction. Our assessment measures retrieval fluency to identify whether retrieval difficulties are contributing to academic challenges.

Processing speed. Processing speed affects how quickly a student can take in, process, and respond to information. Slower processing speed can mean a student understands the material but cannot complete work within time limits, leading to frustration and lower grades that do not reflect their actual knowledge. Processing speed assessment directly informs accommodation recommendations such as extended time on tests and assignments.

What You Will Learn

  • Whether a specific learning disability is present and its precise nature
  • Your child's cognitive strengths and how to build on them for learning
  • Specific academic skill gaps and targeted intervention strategies
  • Recommendations for school accommodations, assistive technology, and tutoring approaches
  • Whether co-occurring conditions (ADHD, anxiety, giftedness) contribute to learning challenges
  • Eligibility for school-based support and accommodations under Ontario education policy
  • Your working memory and long-term retrieval profile, and how memory processes affect learning
  • Processing speed findings and how they relate to academic performance and accommodation needs

School Accommodations

IEP Development

Documentation schools need to develop or update an Individual Education Plan, with specific, evidence-based goals that can be written directly into the IEP.

Assistive Technology

Recommendations for text-to-speech, speech-to-text, graphic organizers, audiobooks, and calculators matched to your child's specific learning profile.

Parent Advocacy Support

Guidance on working with your child's school team, what to request at meetings, and the language you need to advocate for your child's needs.

Post-Secondary Accommodations

Reports meeting documentation requirements for accessibility services at Ontario colleges and universities, including extended test time and note-taking support.

One of the most important outcomes of a learning disabilities assessment is a clear set of recommendations for school accommodations. Here is how the process works in Ontario.

Virtual follow-up available. We offer virtual follow-up consultations for Ontario residents who need support putting school accommodations into practice, preparing for school meetings, or understanding their child's report.

Frequently Asked Questions

At what age should I have my child assessed for a learning disability?
Learning disabilities can be reliably identified starting around age 6 or 7, when children have had enough formal instruction for patterns to emerge. However, concerns can be raised earlier. If your child is struggling in Grade 1 or beyond, an assessment can provide valuable information regardless of age.
Will my child's school accept a private psychoeducational assessment?
Yes. Ontario school boards are required to consider psychoeducational assessments conducted by registered psychologists or psychological associates. Our reports include the information school boards need for the IPRC process and IEP development.
How is a learning disability different from just being a slow learner?
A learning disability is not about overall intelligence or learning speed. People with learning disabilities have average or above-average intelligence but have specific difficulties in one or more academic areas. The key feature is a gap between cognitive ability and academic achievement in a specific domain, such as reading, writing, or math.
Can adults be assessed for learning disabilities?
Yes. Many adults were never assessed as children, especially if they had strong compensatory strategies or attended school before learning disabilities were well understood. An adult assessment can identify learning differences that may be affecting post-secondary education, workplace performance, or daily life. Adult reports can support applications for post-secondary accommodations, workplace accommodations, and OSAP disability grants.
Does a learning disability mean my child will always struggle in school?
No. With the right accommodations, intervention strategies, and support, students with learning disabilities can succeed academically. Many people with learning disabilities develop strong problem-solving skills, creativity, and resilience. Our assessment identifies both the challenges and the specific strategies that will help your child thrive.
Can a child have both a learning disability and ADHD or giftedness?
Yes. Co-occurring conditions are common. A child can have a learning disability alongside ADHD, giftedness, anxiety, or autism. When these conditions overlap, they can mask each other, making identification more complex. Our comprehensive assessment evaluates for multiple conditions to ensure an accurate and complete picture.
Do you assess memory and processing speed?
Yes. Memory and processing speed are core components of our psychoeducational assessment. We evaluate working memory, long-term retrieval, and processing speed because these cognitive processes directly affect reading, writing, and math performance. The results inform specific accommodation recommendations, such as extended time and reduced workload, that are accepted by Ontario school boards and post-secondary institutions.
