One of the most confusing things for parents of kids with dyslexia is watching reading improve while spelling seems to lag far behind. Your child may read a word correctly and then spell that very same word incorrectly a few minutes later. Or maybe you've spent months, or years, using a good spelling curriculum, yet spelling continues to be painfully slow and inconsistent.

For kids with dyslexia, spelling is often one of the more persistent areas of difficulty.

Reading and Spelling Require Different Skills

When a child reads, the word is already in front of them. They can look at the letters, recognize familiar spelling patterns, connect those letters to sounds, and sometimes use the surrounding sentence to help figure out the word.

Spelling works in the opposite direction. There is no word sitting on the page to provide clues.

The child has to:

• think of the word
• identify the individual sounds
• keep those sounds in the correct order
• remember which letters or letter combinations represent those sounds
• recall spelling rules and patterns
• remember any irregular parts of the word
• and write or type the entire word correctly

That's a lot happening at once.

In simple terms, reading provides information that the brain can recognize. Spelling requires the brain to retrieve and produce that information independently. That helps explain why a child can become a fairly capable reader and still struggle significantly with spelling.

Why Is Spelling So Difficult for Kids With Dyslexia?

There isn't just one reason. Several of the underlying processing weaknesses associated with dyslexia can affect spelling, and they often overlap.

Phonological Processing

One of the biggest factors is phonological processing—the ability to recognize, remember, and work with the individual sounds in spoken words.

A child may know exactly what word they want to write but have difficulty pulling that word apart into its individual sounds. For example, a child spelling the word jumped has to hear and hold onto each sound in the word long enough to represent it correctly. If one of those sounds is missed or the sequence gets confused, the resulting spelling may be incomplete or out of order.

Working Memory

Working memory also plays an important role in spelling.

A child has to hold the word in mind while simultaneously thinking about sounds, spelling patterns and rules—and then physically writing or typing the word. For a child with weak working memory, some of that information can disappear before the word is finished.

Working memory affects much more than spelling. It can also affect following directions, reading, writing, math, attention, and remembering previously learned information. If this sounds familiar, read more about working memory and learning struggles.

Retrieval

Sometimes your child really does know how to spell a word. The difficulty is retrieving that information quickly and reliably.

This explains one of the things parents find especially puzzling: a child may spell a word correctly one day and incorrectly the next. The information may have been learned. It just isn't automatic enough yet to be retrieved consistently.

Orthographic Memory

Orthographic memory refers to our ability to remember written words and familiar spelling patterns. As skilled readers and spellers gain experience, thousands of common patterns become increasingly automatic.

For many kids with dyslexia, building that storehouse of spelling patterns requires much more direct instruction, repetition, and time. This is why dyslexic spelling can sometimes look so inconsistent.

A child may even spell the same word two or three different ways on one page. From the outside, that can look careless. But often it reflects just how much cognitive work is happening underneath the surface.

Writing Makes Spelling Even Harder

Spelling becomes even more difficult when a child is writing sentences, paragraphs, or longer assignments. Now spelling isn't the only thing the brain is trying to manage.

Your child may also be thinking about:

• what they want to say
• how to organize their ideas
• grammar
• punctuation
• handwriting or typing
• the directions for the assignment
• and what they're supposed to do next

For a child with dyslexia, spelling becomes one more demand on an already busy system. This is why a child may spell a word correctly during a focused spelling lesson and then misspell that same word later while writing a paragraph.

That doesn't necessarily mean the instruction isn't working.

t may simply mean the spelling hasn't become automatic yet.

If handwriting and getting ideas onto paper are also unusually difficult, there may be more going on than dyslexia alone. Dysgraphia can affect handwriting, spelling, organization, grammar, and written expression. You can learn more in my post Trouble With Handwriting? It Could Be Dysgraphia.

English Spelling Is Complicated—but It Isn't Random

English spelling can feel incredibly frustrating. The problem is that English spelling represents more than sound.

Our spelling system also reflects:

• spelling patterns
• syllable types
• word meanings
• prefixes and suffixes
• roots
• and even the history and origin of words

That's why simply telling a child to “sound it out” isn't always enough.

Consider the word sign.

If you spell it only by sound, that silent g doesn't make much sense.

But look at related words:

sign → signal → signature

Now the spelling starts to tell us something about the relationship between the words.

This is where morphology becomes especially useful. Morphology is the study of meaningful parts of words, including roots, prefixes, and suffixes.

A child who understands that help, helpful, helping, and helpless all share the same base word isn't memorizing four completely unrelated spellings. They are learning how words are built.

For older dyslexic students in particular, understanding meaningful word parts can make spelling much more logical.

Why Memorizing Spelling Words Isn't Enough

Traditional spelling instruction often focuses heavily on memorizing a list of words.

A child studies the words for several days, remembers them temporarily, and then may spell those very same words incorrectly later in ordinary writing.

That's because memorizing individual words isn't the same as developing lasting spelling knowledge. Kids with dyslexia generally need much more connection between the words they are learning.

Instead of unrelated word lists, effective instruction teaches words according to things like:

• common sound-spelling patterns
• spelling rules and generalizations
• syllable types
• prefixes and suffixes
• roots and meaningful word parts

Dictation can also be especially useful because it requires a child to hear a word or sentence, remember it, apply the spelling patterns they have learned, and then write it in context.

This kind of explicit, structured, cumulative teaching is part of the Orton-Gillingham approach to teaching reading and spelling.

What Good Spelling Instruction Looks Like

Fortunately, homeschool parents do not need to create all of this themselves. There are excellent structured spelling programs designed for struggling and dyslexic learners that guide parents through what to teach and when.

I've put together a more detailed guide to homeschool spelling curriculum for students with dyslexia that includes several programs we've used and recommended over the years.

Even when you're following a curriculum, though, it helps to know what effective instruction should look like. Look for spelling instruction that is:

Explicit. Patterns and rules are actually taught rather than expected to be picked up naturally.

Systematic. Skills build logically from simpler concepts to more difficult ones.

Cumulative. Previously learned concepts continue to come back for review.

Repetitive. Kids with dyslexia usually need much more exposure and practice before skills become automatic.

Connected to reading and writing. Students aren't simply memorizing isolated words.

Short, frequent practice is often more helpful than very long spelling sessions. And as kids get older, instruction in roots, prefixes, suffixes, and word origins becomes increasingly important.

Don't Give Up on a Good Spelling Program Too Quickly

This is an important one for homeschool parents. When spelling progress is slow, it's very tempting to assume:

“This curriculum isn't working. Maybe we need something else.”

Sometimes that really is true. But spelling progress for a child with dyslexia can simply take a long time.

Before abandoning a program, ask:

• Is the instruction explicit?
• Is it systematic?
• Does it include plenty of repetition and review?
• Are previously learned patterns continually revisited?
• Is my child making gradual progress, even if it is slower than I expected?

If those pieces are in place, continually jumping from one curriculum to another may actually make progress harder because the child loses some of the benefits of cumulative instruction.

I see this same issue with reading programs, too. If you're wondering whether the problem is truly the curriculum or whether your child simply needs more time and review, my article on when to switch Orton-Gillingham programs may help.

Look for growth over time rather than expecting spelling to suddenly become easy.

Spelling Instruction and Accommodations Can Happen Together

Especially as kids get older, we don't want weak spelling skills to prevent them from communicating ideas that are far more sophisticated than their spelling ability.

A child can continue working on spelling while also using tools such as:

• spellcheck
• predictive text
• speech-to-text
• typing
• word banks
• personal spelling dictionaries

Using assistive technology doesn't mean you've given up on teaching spelling. It simply prevents spelling from becoming a barrier to learning.

If your student has a fantastic idea for a history paper, we don't want all of their mental energy going into remembering how to spell every word. We want them to be able to communicate what they know.

This is an important distinction: remediation strengthens a weak skill, while accommodations provide access to learning while that weakness still exists. Our kids often need both.

I explain this in more depth in my new guide to homeschool accommodations for dyslexia and ADHD.

The Goal Isn't Perfect Spelling

If your child with dyslexia is still struggling with spelling, it doesn't automatically mean you're doing something wrong. And it doesn't necessarily mean your curriculum isn't working.

Spelling is one of the more demanding literacy skills, and for many dyslexic learners it simply takes longer to become automatic. Continue using explicit, systematic instruction.

Pay attention to the patterns your child is beginning to understand rather than looking only at individual spelling errors. Use accommodations when they are needed.

And remember that the ultimate goal isn't perfect spelling.

The goal is helping your child become a capable communicator while continuing to strengthen the skills that are difficult for them.

Want to Better Understand How Your Child Learns?

One of the biggest shifts we can make as parents is learning to understand why our children struggle.

Once you understand what's happening underneath a difficulty, whether that's phonological processing, working memory, slow retrieval, executive function, or another learning difference, it becomes much easier to choose teaching methods and accommodations that actually fit your child.

That's the purpose behind my Parent Education Classes for Homeschooling Kids With Dyslexia and Other Learning Differences.

Because the more you understand how your child learns, the better equipped you are to teach them.
