Not All Dyslexia Looks the Same: Understanding Different Reading Profiles

As a school psychologist, I frequently evaluate children who experience difficulty with reading. Through my years of experience and evidence-based practice, I have come to recognize that two students can struggle with the same reading assignment for very different reasons. One may have difficulty connecting letters to their corresponding sounds and decoding unfamiliar words, while another may successfully sound out words but struggle to recognize familiar words automatically. A third may experience difficulties in both areas. Although their reading performance may look similar on the surface, understanding the underlying processes is essential to determining how best to support them.

For parents, the first indication that something may be wrong often comes during homework or reading time. A child may hesitate over familiar words, guess at unfamiliar ones, read slowly, or become frustrated when asked to read aloud. Some children demonstrate strong listening comprehension and can discuss a story in detail when someone reads it to them, yet struggle to read that same story independently. Others may appear to read adequately during the early elementary years, only to experience greater difficulty as reading demands increase. These observations provide valuable information, but they do not necessarily tell us why a child is struggling. To better understand these differences, we need to look at the processes involved in learning to read and how those skills develop over time.

Dyslexia is a learning disability that affects the development of accurate and efficient word reading and/or spelling. Although difficulties with phonological processing are common among individuals with dyslexia, they are not universal, and the specific pattern of reading difficulties can vary considerably from one child to another. The International Dyslexia Association's updated definition recognizes this variability, emphasizing that dyslexia can involve different underlying processes and degrees of difficulty. Understanding this distinction is important because a diagnosis of dyslexia does not mean that every child experiences reading in the same way.

When children learn to read, they gradually develop the ability to recognize letters, connect those letters to speech sounds, combine sounds to decode words, and recognize familiar written words with increasing accuracy and automaticity. As these skills become more efficient, children can devote more of their attention to understanding what they read rather than concentrating primarily on identifying individual words. For children with dyslexia, difficulties in one or more of these processes can interfere with that progression. Researchers have described several patterns of reading difficulty, including phonological, surface, and mixed profiles. Although these terms can help explain differences in reading performance, they are descriptive classifications rather than separate, universally accepted clinical diagnoses. A child's reading profile may also change as their skills develop and they receive instruction.

One pattern commonly discussed in the literature is phonological dyslexia, sometimes referred to as dysphonetic dyslexia. Children with this profile experience particular difficulty using their knowledge of letters and sounds to decode unfamiliar words. For example, a child may recognize a word they have encountered many times but struggle when presented with a new word that requires them to identify and blend its individual sounds. Rather than carefully decoding the entire word, they may rely on its first letter, overall appearance, or surrounding context to make a guess. Parents may notice that their child can read certain familiar words but becomes frustrated when encountering new vocabulary. Spelling may also be difficult because writing an unfamiliar word requires the child to identify the sounds within it and connect those sounds to appropriate letters or letter combinations.

From an evaluation standpoint, this pattern may become apparent when examining a child's phonological awareness, knowledge of letter-sound relationships, ability to decode unfamiliar words, and spelling. Phonological awareness refers to the ability to recognize and manipulate the sounds within spoken language. For example, a child may be asked to identify individual sounds in a word, blend sounds together, or determine what remains when a particular sound is removed. A child may demonstrate stronger skills in some of these areas while experiencing greater difficulty in others. Understanding the specific pattern helps identify which foundational reading skills may need additional instruction. For children who struggle with phonological decoding, explicit and systematic instruction in speech sounds, letter-sound relationships, and spelling patterns can help them develop more reliable strategies for reading unfamiliar words rather than depending primarily on guessing or memorization.

Another reading profile described in the research is surface dyslexia. Children with this pattern may demonstrate relatively stronger phonological decoding skills but experience difficulty developing accurate and efficient recognition of familiar written words, particularly words that do not follow common spelling-to-sound patterns. For example, a child may attempt to read the word said by applying a more common pronunciation to its letters rather than recognizing the word's established pronunciation. They may be able to sound out many unfamiliar words but continue to read familiar words slowly or inconsistently. This can be confusing for parents because the child may appear to understand how phonics works, yet reading continues to require considerable effort.

One process involved in skilled reading is the development of orthographic knowledge, which includes learning how letters and letter combinations are organized within written words. As children become more proficient readers, they develop increasingly accurate connections among a word's spelling, pronunciation, and meaning. These connections allow familiar words to be recognized efficiently without having to consciously sound out every letter each time. A child with a surface-type reading profile may have difficulty developing this level of automatic word recognition, and spelling may also be affected. For example, the child may produce a spelling that accurately represents the sounds in a word but does not reflect its conventional written form. Importantly, these difficulties do not necessarily mean that the child simply needs to memorize more words by sight. Efficient word recognition develops through repeated opportunities to connect written words with their pronunciations and meanings.

When evaluating a student who demonstrates this pattern, I consider how accurately and efficiently they read familiar words, unfamiliar words, and words with less predictable spelling patterns. I also examine spelling and other relevant reading skills to better understand where the difficulty occurs. Research supports the existence of surface-like reading profiles, but the underlying reasons for these difficulties can vary. As a result, surface dyslexia is most appropriately understood as a description of reading performance rather than proof of one specific cognitive deficit. This distinction is important when considering intervention because children with similar reading behaviors may still have different instructional needs.

Some children experience significant difficulties with both phonological decoding and efficient recognition of familiar written words. This is often described as a mixed reading profile. A child may struggle to sound out an unfamiliar word during a reading assignment and then have difficulty recognizing that same word when it appears again several sentences later. Their reading may be slow, effortful, and inconsistent, and spelling difficulties may be particularly noticeable. When identifying individual words requires so much attention, the child may have fewer cognitive resources available to understand the overall meaning of what they are reading. Consequently, some students demonstrate much stronger comprehension when listening to a story than when reading that same material independently.

This difference between listening comprehension and reading comprehension can provide important information about a child's learning profile. A student may understand complex vocabulary, make thoughtful connections, and discuss sophisticated ideas when information is presented orally, yet struggle to demonstrate those same abilities when required to read independently. The difficulty may not be with understanding the information itself but with accessing it through written language. Research has found that mixed reading profiles are common among children with developmental dyslexia, although students with similar patterns of reading difficulty may demonstrate different underlying cognitive strengths and weaknesses. For this reason, intervention should address the specific skills that are affected rather than relying solely on the subtype label.

One of the most important lessons my evaluation work has reinforced is that a child's reading performance tells us what they are doing, but it does not always explain why they are having difficulty. A student who guesses at words may have weak decoding skills, while another may have developed that habit after years of frustration with reading. A child who reads slowly may struggle to recognize familiar words automatically, while another may be carefully applying newly learned decoding strategies. These distinctions matter because children can demonstrate similar behaviors for different reasons, and the most appropriate support depends on understanding what is contributing to the difficulty.

During a comprehensive psychoeducational evaluation, I consider how a child's reading skills have developed across several areas, including phonological processing, decoding, word recognition, spelling, reading fluency, and reading comprehension. I also consider relevant aspects of language development, cognitive processing, educational history, and instructional experience. Equally important is understanding the child's strengths. A student may demonstrate strong verbal reasoning, listening comprehension, vocabulary, or background knowledge despite experiencing significant difficulty with word reading. Recognizing these abilities helps us understand what the child knows and can do independently of the reading difficulty, while also identifying strengths that may support their learning.

I also consider how reading difficulties affect the child's everyday functioning. A student may be able to read a short passage accurately during an individual assessment but struggle to complete lengthy classroom assignments within the expected time. Another may avoid reading aloud, become frustrated during homework, or begin to question their academic abilities because reading requires considerably more effort than it does for their peers. These experiences are important because the impact of dyslexia extends beyond individual test scores. Understanding how reading difficulties affect a child's academic performance, confidence, and participation helps parents and educators make more informed decisions about instruction, intervention, and accommodations.

Another important consideration is that reading difficulties may become more noticeable or change in appearance as children progress through school. During the early elementary years, difficulties may emerge as children learn letter-sound relationships, begin decoding words, and develop basic spelling skills. By the upper elementary grades, some children have developed enough compensatory strategies to read familiar material with reasonable accuracy, but they may continue to struggle with unfamiliar vocabulary, reading fluency, or spelling. As students enter middle and high school, academic demands become increasingly complex, requiring them to read longer passages, learn specialized vocabulary, complete assignments independently, and extract information from increasingly sophisticated texts.

A teenager with dyslexia may no longer demonstrate the same obvious word-reading errors that were present in elementary school. Instead, difficulties may become more apparent through slow reading, reduced reading stamina, spelling weaknesses, avoidance of lengthy assignments, or the amount of time required to complete academic work. Some students become quite skilled at compensating for their reading difficulties, making those challenges less noticeable to others. This is why I encourage families and educators to consider a child's developmental and educational history rather than relying solely on how their reading looks at one particular moment. Dyslexia can continue to affect reading and spelling throughout adolescence and adulthood, even as individuals develop strategies that allow them to function successfully in many areas.

When parents learn that their child has dyslexia, they often want to know what the diagnosis means for their child's future and what they can do to help. Those are important questions, and I believe the answers begin with understanding the individual child. A diagnosis can help explain why reading has been difficult, but it does not tell us everything about how a child learns. Two students with dyslexia may have different reading profiles, different strengths, different instructional histories, and different responses to intervention. The terms dysphonetic, surface, and mixed can help describe some of those differences, but they should not become rigid categories that define a child's abilities or determine their educational opportunities. In clinical diagnostic terminology, dyslexia is generally considered within the framework of specific learning disorder with impairment in reading, while these reading profiles are descriptive classifications rather than separate DSM-5-TR diagnoses.

I also want parents to understand that reading difficulties do not define a child's intelligence, creativity, curiosity, or potential. A child who struggles to decode a paragraph may have a remarkable understanding of the ideas within it when those ideas are presented in a more accessible format. Recognizing that difference allows us to support the development of reading skills while continuing to nurture the child's broader academic and personal growth. Ultimately, understanding dyslexia requires us to look beyond whether a child can read a particular word or complete a particular assignment. We need to understand how they approach reading, where the process becomes difficult, and what helps them make progress. A diagnosis helps us recognize the difficulty, but understanding the individual reading profile helps us determine what to do next.

If you have concerns about your child's reading development, a comprehensive psychoeducational evaluation can help identify their individual strengths, areas of difficulty, and educational needs. At Unlock Learning Palm Beach, we work with families to better understand how their children learn and provide information that can help guide meaningful support at home and in school.
