Dyslexia
Dyslexia is a brain-based learning difference that affects reading, spelling, and written language—not intelligence or effort. This page explains common signs, when they appear, how dyslexia is evaluated, and the evidence-based supports that help children become confident readers.

What is Dyslexia?
Dyslexia is a specific learning disorder that affects a person’s ability to read, spell, and decode written language accurately and fluently. It is a neurodevelopmental condition, meaning it reflects differences in how the brain processes language, particularly written language. Dyslexia is not related to intelligence, motivation, or effort. Many people with dyslexia are bright, creative, and capable learners who struggle specifically with reading and written language.
Medical and educational organizations describe dyslexia as:
- A brain-based learning difference that primarily affects reading and spelling
- Usually identified in early elementary school, when children begin learning to read
- Characterized by persistent difficulty with:
- Phonological processing (understanding and manipulating speech sounds)
- Decoding written words
- Reading fluency and accuracy
- Spelling and written expression
Dyslexia is not caused by poor teaching, lack of exposure to books, or parenting style. Dyslexia is usually lifelong, but early identification and evidence-based reading instruction can improve reading skills and confidence.
What are common signs of dyslexia in children?
Signs often cluster around reading, language processing, and written expression. Professionals diagnose dyslexia using standardized criteria (DSM-5) under Specific Learning Disorder with impairment in reading.
A. Early language and pre-reading signs (preschool years)
Possible signs include:
- Delayed speech development
- Difficulty learning nursery rhymes or rhyming words
- Trouble recognizing or producing rhymes
- Difficulty learning letter names or letter sounds
- Trouble remembering sequences (days of the week, alphabet, counting)
- Difficulty pronouncing long or unfamiliar words
B. Reading and decoding difficulties (early elementary school)
Possible signs include:
- Difficulty sounding out words
- Reading slowly and with great effort
- Frequent guessing at words rather than decoding them
- Skipping or adding words while reading
- Difficulty recognizing common sight words
- Avoiding reading whenever possible
C. Spelling and writing difficulties
Possible signs include:
- Very poor or inconsistent spelling
- Difficulty sounding out words to spell them
- Writing letters or words out of order
- Trouble organizing written work
- Writing far less than expected for age
- Difficulty copying from the board
D. Later signs (upper elementary school and beyond)
Possible signs include:
- Slow reading speed and poor reading fluency
- Difficulty understanding what was read due to effort spent decoding
- Trouble learning foreign languages
- Avoidance of reading-heavy subjects
- Low confidence or frustration related to schoolwork
Having some of these difficulties occasionally is common. Dyslexia is considered when challenges are persistent, significant, and interfere with academic progress.
When do signs often show up? (approximate)
A. Preschool
- Difficulty learning letter sounds
- Trouble with rhymes and word play
- Delayed expressive language
B. Kindergarten to grade 2
- Difficulty learning to read despite instruction
- Trouble connecting sounds to letters
- Slow progress compared to peers
C. Grade 3 and beyond
- Reading remains slow and effortful
- Spelling remains poor
- Academic performance affected by reading demands
What should I do if I think my child has dyslexia?
A. Screening and evaluation
Families can request an evaluation through:
- The child’s school
- A private psychologist or neuropsychologist
- A speech-language pathologist (for early language concerns)
B. Comprehensive evaluation
A full evaluation may include:
- Standardized reading and spelling tests
- Assessment of phonological awareness and decoding skills
- Cognitive testing to understand learning strengths and weaknesses
- Review of academic history
- Teacher reports and classroom observations
- Screening for co-occurring conditions such as ADHD or anxiety
C. Diagnosis
Under DSM-5, dyslexia is diagnosed as Specific Learning Disorder with impairment in reading. Criteria include:
- Persistent difficulties with word reading accuracy, reading rate or fluency, or spelling
- Skills substantially below age expectations
- Difficulties present for at least 6 months despite targeted instruction
- Difficulties that interfere with academic or daily functioning
- Challenges not better explained by intellectual disability or lack of instruction
D. Intervention and support
Evidence-based supports can include:
- Reading instruction
- Structured literacy programs
- Explicit, systematic phonics instruction
- Multisensory teaching approaches
- Frequent practice with feedback
- School supports
- Individualized Education Programs (IEPs) or 504 plans
- Extended time on tests and assignments
- Reduced reading load when appropriate
- Access to audiobooks and text-to-speech tools
- Alternative ways to demonstrate knowledge
- Emotional support
- Addressing frustration and reading-related anxiety
- Building self-esteem through strengths-based learning
- Teaching self-advocacy skills
What else should I know?
A. Dyslexia is common
Dyslexia affects approximately 10–20% of the population, making it one of the most common learning differences.
B. Dyslexia is not a vision problem
It is not caused by seeing letters backward or poor eyesight.
C. Co-occurring conditions are common
Common co-occurring conditions include:
- ADHD
- Dyscalculia
- Developmental language disorder
- Anxiety
D. Strengths are common
Many people with dyslexia show:
- Strong problem-solving skills
- Creativity and originality
- Big-picture thinking
- Strengths in oral communication
E. Early intervention matters
Early identification and structured reading instruction can improve:
- Reading accuracy and fluency
- Academic success
- Confidence and motivation
What can I do to help my child right now?
Step 1. Trust your observations
Parents often notice reading struggles before formal testing occurs.
Step 2. Talk to your child’s teacher and pediatrician
Ask whether reading progress is developmentally appropriate.
Step 3. Request a school evaluation
Parents have the right to request a formal evaluation for learning disabilities.
Step 4. Support reading at home
- Read aloud to your child
- Use audiobooks alongside print
- Encourage reading without pressure
- Praise effort, not speed
Step 5. Learn your child’s educational rights
Understand IEPs, 504 plans, and evidence-based reading instruction requirements.
Step 6. Support emotional well-being
Repeated reading failure can affect self-esteem. Emotional support is essential.
Key Takeaways
✓ Dyslexia is a brain-based learning difference that affects reading, spelling, and written language.
