The Complete Guide to Dyslexia in the UK (2026)

Can schools diagnose dyslexia in the UK?

Schools can identify learning difficulties and may carry out screening assessments, but they cannot provide a formal diagnostic diagnosis of dyslexia. A full diagnostic assessment must be completed by a qualified specialist assessor or educational psychologist who is trained to evaluate the cognitive processes involved in learning. Schools may recommend further assessment if a child continues to experience significant literacy difficulties despite appropriate teaching and support.

At what age can dyslexia be diagnosed?

Dyslexia is usually identified once a child has begun learning to read and write. For many children this is during primary school, often between the ages of 8 and 9, when reading and spelling demands increase. However, signs of dyslexia can often be noticed earlier, particularly difficulties with rhyme patterns, remembering sequences, or learning letter sounds. Assessments can also take place in adolescence or adulthood if difficulties have not previously been recognised.

Is dyslexia a learning disability?

In the UK, dyslexia is typically described as a specific learning difficulty rather than a general learning disability. This means the difficulty is related to particular areas of learning, particularly reading, spelling and written language, rather than overall intellectual ability. Many individuals with dyslexia have average or above-average intelligence and strong reasoning skills.

Can adults be diagnosed with dyslexia?

Yes. Many adults only discover they are dyslexic later in life. This often happens when workplace demands increase, when preparing for professional exams, or when a parent recognises similar learning patterns while supporting their child. An adult diagnostic assessment explores cognitive processing, memory and literacy skills to understand how dyslexia may be affecting work or everyday tasks.

Does dyslexia affect intelligence?

No. Dyslexia is not linked to intelligence. It reflects differences in how the brain processes language and written information. Many dyslexic individuals demonstrate strong abilities in reasoning, creativity, problem solving and big-picture thinking. Difficulties arise because reading and writing require specific cognitive processes that may operate differently in dyslexic learners.

What are the first signs of dyslexia in children?

Early signs of dyslexia often appear when children begin learning letter sounds and reading. Parents may notice difficulties remembering letter–sound relationships, guessing words rather than decoding them, or inconsistent spelling of familiar words. Some children may also struggle to remember what they have just read, even when they read the words accurately. Earlier in childhood, difficulties learning nursery rhymes or recognising rhyme patterns can sometimes be an early indicator.

Can a child be bright and still have dyslexia?

Yes. Many dyslexic children are bright, curious and verbally articulate. Strong reasoning and language skills can sometimes mask reading and spelling difficulties, meaning dyslexia may go unnoticed for longer. These children often work extremely hard to compensate for their difficulties, which is why their challenges may not always be immediately recognised in school.

Why does my child guess words when reading?

Children who guess words when reading often do so because decoding strategies are not fully secure. Instead of sounding out unfamiliar words, they may rely on context clues, pictures or the first letter of the word. While this strategy can help a child continue reading, it often leads to inaccuracies and can make comprehension more difficult.

Why does my child forget what they have just read?

Reading comprehension depends on several cognitive processes, including working memory. If a child needs to focus heavily on decoding each word, their working memory may become overloaded, making it harder to retain the meaning of the text. As a result, they may finish a paragraph but struggle to explain what it was about.

Does dyslexia affect spelling?

Spelling difficulties are one of the most common features of dyslexia. Because spelling relies on accurately recognising and recalling sound patterns within words, weaknesses in phonological processing can make spelling unpredictable. Dyslexic learners may spell the same word differently several times within the same piece of writing.

Can dyslexia be cured?

Dyslexia is not something that needs to be “cured.” It reflects a different way of processing language and written information. However, with appropriate teaching approaches, targeted support and effective strategies, individuals with dyslexia can learn to read and write successfully and develop strong skills in many areas.

Is dyslexia genetic?

Research suggests that dyslexia often runs in families. Many parents who seek an assessment for their child recognise similar experiences in their own schooling. While genetics may increase the likelihood of dyslexia, environmental factors such as teaching approaches and early support also influence how reading develops.

What is the difference between dyslexia and a reading delay?

A reading delay may occur when a child has had limited reading experience or inconsistent instruction. Dyslexia, however, reflects differences in the cognitive processes that support reading development, particularly phonological processing and working memory. A diagnostic assessment helps determine whether reading difficulties are consistent with a dyslexic profile.

How common is dyslexia?

Estimates vary, but research suggests that around 10 percent of the population may experience some degree of dyslexia, with a smaller proportion experiencing more significant difficulties. Because dyslexia exists along a continuum, individuals may experience different patterns and levels of challenge.

When should I consider a dyslexia assessment for my child?

Parents may consider a dyslexia assessment if their child continues to experience persistent reading or spelling difficulties despite appropriate teaching and practice. Other indicators include large gaps between verbal ability and literacy skills, ongoing frustration with reading tasks, or increasing loss of confidence related to schoolwork.
