Heggerty decodable books: what parents need to know

Last updated 2026-07-09

What are Heggerty decodable books and who makes them?

Heggerty is a literacy curriculum company founded by Michael Heggerty, a principal and reading specialist in Illinois. The brand is best known for its phonemic awareness curriculum, which became one of the most widely adopted in U.S. elementary schools after research on the science of reading gained mainstream traction in the 2010s. The decodable book series came later, as an extension of that curriculum into connected text practice.

Decodable books, in general, are short books written so that almost every word follows the phonics patterns a student has already learned. That is the key design rule. A book at the short-vowel CVC stage, for example, would use words like "sit," "hop," and "tan" and would not sneak in words like "said" or "they" that require knowledge the child doesn't have yet. Research on how children learn to read consistently shows that decodable texts help early readers practice phonics patterns in context, which builds both accuracy and fluency ^[1][2].

Heggerty's decodable books are designed to align directly with their phonics curriculum scope and sequence. That alignment is the thing that sets them apart from generic decodable books. If your child's classroom uses Heggerty Phonics, these books are calibrated to match where the class is in that sequence. If the school uses a different program, you'd need to compare scopes to see whether the books match what your child currently knows.

The books are published in sets, organized by phonics skill level rather than by reading level in the traditional Lexile or Guided Reading sense. Each set targets specific sound-spelling patterns: consonants and short vowels first, then blends and digraphs, then long vowel patterns, and so on.

How are Heggerty decodable books different from other decodable book series?

There are now dozens of decodable book series on the market: BOB Books, Flyleaf Publishing, Little Blossom Stories, UFLI Foundations readers, Jolly Readers, and many more. So why choose Heggerty over another series?

The honest answer is: it depends entirely on which phonics curriculum your child's school or tutor uses. Decodable books work best when the phonics patterns in the book match the patterns already taught ^[2]. Mixing curricula haphazardly can mean a child hits words that encode patterns they haven't seen, which pushes them back into guessing from context or pictures rather than decoding.

Here's how Heggerty stacks up against a few other common series:

Series	Curriculum alignment	Average cost per book	Library availability	Notes
Heggerty Decodables	Heggerty Phonics	~$4-7 per book	Limited; growing	New-ish series, school sets available
BOB Books	Generic phonics order	~$3-5 per book	Very common	Long-established; well-stocked in most libraries
Flyleaf Publishing	Multiple curricula	~$4-6 per book	Rare	Strong phonics control; less brand recognition
UFLI Decodables	UFLI Foundations	Free PDF download	N/A (free)	Excellent free option from University of Florida [3]
Little Blossom Stories	Orton-Gillingham sequence	~$5-8 per book	Rare	Good for OG-based tutoring

The UFLI Foundations decodable texts are worth flagging separately. The University of Florida Literacy Institute makes them available as free downloads for home printing ^[3]. If cost is a barrier, those are genuinely good and the phonics scope is rigorous.

For parents whose child uses Heggerty Phonics at school, the Heggerty decodable books are a natural at-home complement because the sequences match. For families whose child uses Orton-Gillingham tutoring or a different structured literacy program, a different series may fit better.

Can I find Heggerty decodable books at a library?

Sometimes, but don't count on it. This is one of the most common questions parents ask, and the honest answer is that stock varies a lot by region.

Public libraries are increasingly carrying decodable books as awareness of the science of reading has grown, and many urban library systems now have dedicated decodable book sections. Heggerty's series is newer and less widely distributed than BOB Books or some competitors, so availability is patchy.

Here's how to actually track down Heggerty decodable books at a library:

1. Search your library's online catalog directly for "Heggerty decodable" or "Heggerty phonics readers." Most library catalogs let you place a hold if a copy exists anywhere in the system. 2. Ask your children's librarian specifically. Many libraries now have a reading specialist liaison or a staff member focused on early literacy. They can request titles through interlibrary loan if your branch doesn't have them. 3. Ask your child's school. School libraries sometimes have classroom sets that can be sent home, especially if the school already uses Heggerty Phonics. 4. Contact your school district's curriculum coordinator. Districts that adopted Heggerty Phonics often bought decodable books in sets and may have a lending process for families.

Decodable books at the library are a real, growing category. If your local library doesn't have Heggerty specifically, ask them to order copies. Most public libraries take purchase requests seriously, especially for early literacy materials. A simple email citing demand can get books ordered within a few months.

If the library route doesn't pan out, the UFLI free decodables ^[3] and BOB Books (widely stocked) are solid backups while you wait.

What phonics skills do the Heggerty decodable books cover?

Heggerty organizes its decodable books to mirror the scope and sequence in Heggerty Phonics, the structured literacy program the company sells to schools. The general progression follows what reading researchers call a logical phonics sequence: simple to complex, building each new pattern on the ones already mastered ^[1].

The broad sequence looks like this:

• Set 1: Single consonants and short vowels (CVC words: "bat," "sit," "hop")
• Set 2: Consonant blends and short vowels ("frog," "clip," "stamp")
• Set 3: Digraphs ("sh," "ch," "th," "wh")
• Set 4: Long vowel patterns with silent E ("cake," "mine," "rode")
• Set 5: Long vowel teams ("rain," "bead," "boat")
• Set 6: R-controlled vowels ("car," "bird," "hurt")
• Set 7: More complex vowel patterns and multisyllabic words

The exact set numbering and titles may vary slightly by edition. Check Heggerty's own website for the current set structure before you buy.

Each book in a set is short, usually 8 to 16 pages, with controlled vocabulary that sticks tightly to the target pattern. Stories include a small number of high-frequency "heart words" (words like "the," "a," and "I") that are taught directly as exceptions rather than treated as words to guess.

One thing to watch: some series claim to be decodable but include far too many irregular or untaught words. A legitimate decodable text should have roughly 80 to 90% of its words fully decodable using patterns taught to that point, with any exceptions flagged. Ask your child's teacher or reading specialist to check a sample book if you're unsure.

Who should use Heggerty decodable books and who shouldn't?

Heggerty decodable books work best for:

• Kids in kindergarten through second grade who are in the early stages of phonics instruction and need connected text practice that matches what they're learning.
• Children with dyslexia or other reading disabilities who are getting structured literacy intervention. Decodable texts are a cornerstone of evidence-based reading intervention for dyslexia ^[4][5]. They let the child practice decoding without the crutch of guessing from pictures or context.
• Any child whose school already uses Heggerty Phonics, because the scope alignment means there's no mismatch between what's taught and what's in the book.

They're probably not the right fit for:

• A child who already reads fluently at a second-grade level or above. At that point, you want interesting books at their independent reading level, not controlled decodable texts.
• A child getting Orton-Gillingham tutoring with a sequence that differs a lot from Heggerty's. A misaligned decodable series can confuse more than it helps.
• Families mainly looking for library materials, at least right now. The series is newer and library stock is patchy. BOB Books or UFLI free decodables are more immediately accessible.

Parents of children who have been identified with dyslexia should know that decodable books are not a standalone intervention. They're a practice tool. The teaching of phonics patterns needs to happen first, through explicit, systematic instruction, before a child reads those patterns in a decodable book. That's the sequence the research supports ^[1][2].

If you suspect your child has dyslexia but hasn't been formally assessed, signs of dyslexia and dyslexia test are good starting points before you pick any reading materials.

How do Heggerty decodable books connect to the science of reading?

The science of reading is a body of research, built up over roughly 40 years, about how children actually learn to read. The most widely cited frameworks are Scarborough's Reading Rope and Linnea Ehri's phases of word reading development. The policy document most parents encounter is the National Reading Panel's 2000 report, which named five components of effective reading instruction: phonemic awareness, phonics, fluency, vocabulary, and comprehension ^[6].

Decodable books address two of those five: phonics and fluency. They give children a structured way to apply phonics knowledge in connected text, which is different from doing isolated decoding drills. Reading words in a sentence, even a simple one, builds the fluency pathway that eventually becomes automatic.

Heggerty's phonemic awareness curriculum has reasonably strong uptake data. As of 2023, the company reported use in tens of thousands of classrooms across the U.S. The decodable book series is newer, so independent efficacy studies on the Heggerty decodable books themselves are limited. The broader evidence base for decodable texts as a category is solid ^[1][2], but parents should not read that as meaning every product labeled "decodable" is equally rigorous.

The What Works Clearinghouse, run by the Institute of Education Sciences at the U.S. Department of Education, reviews reading programs and rates their evidence base ^[7]. As of mid-2025, the Heggerty decodable book series had not been reviewed as a standalone intervention by WWC, though Heggerty's phonemic awareness curriculum had some supporting evidence. Check the WWC site directly for the current status.

For children with phonological dyslexia, where the core deficit is in phoneme awareness and phoneme-grapheme mapping, decodable books that match explicit phonics instruction are among the best-supported reading tools available.

How much do Heggerty decodable books cost and where can you buy them?

Individual Heggerty decodable books generally run $4 to $7 each at retail. Sets are sold in bundles, and school pricing is usually lower than retail. As of 2025, Heggerty sells directly through their website at heggerty.com, and some titles are available through educational retailers like Really Good Stuff or School Specialty.

School-level sets (classroom packs of 6 copies per title) are sold in bulk and are the main purchase channel for educators. A single-level classroom set can run $150 to $300 depending on how many books it includes. That's not a realistic buy for most families.

For home use, the practical options are:

1. Buy individual books targeting the specific skill level your child is practicing right now. One book per level as a sampler is reasonable. You don't need the whole series. 2. Check with your child's school or district about borrowing classroom sets. 3. Use the free UFLI decodables as a complement ^[3]. They're rigorous, free, and cover a similar phonics scope. 4. Watch for library copies, especially if you're in a district that adopted Heggerty Phonics districtwide.

Spending $50 to $80 on a targeted selection of 10 to 15 books covering your child's current phonics range is a reasonable home investment. Buying the full series before you know it matches your child's instruction is a waste of money. Start narrow, see whether the books fit your child's specific sequence, then expand.

For families managing IEP costs, decodable books used as part of a documented reading intervention can sometimes be requested under the supplementary aids and services section of an IEP under IDEA ^[8]. That doesn't guarantee the school will fund them, but it's a legitimate ask.

Can a child use Heggerty decodable books without the Heggerty phonics curriculum?

Yes, with some caveats.

The decodable books are designed to pair with Heggerty Phonics, but the patterns they teach are standard patterns that show up in nearly every structured literacy sequence. CVC words, blends, digraphs, long vowel patterns: these are the same building blocks in Orton-Gillingham, Wilson Reading System, UFLI Foundations, and most other programs. The order may vary slightly, but the patterns themselves are universal.

So a child doing Wilson Reading System tutoring can still read Heggerty decodable books that cover already-mastered patterns, as long as a parent or teacher checks the book's target pattern against what the child has actually been taught. The mismatch risk is real but manageable with a little attention.

What you don't want to do is hand a child any decodable book without knowing where they are in their phonics sequence. "Decodable" only helps if it's decodable for that specific child at that specific moment. A book full of r-controlled vowels is not decodable for a child who has only learned short vowels, no matter what the cover says.

Not sure what patterns your child has mastered? Ask their teacher for a phonics skills checklist. Most structured literacy programs include one. A reading specialist or educational therapist can also run a quick phonics screener. Knowing your child's current phonics level is the prerequisite to choosing any decodable books, Heggerty or otherwise.

The ReadFlare free reading tools include a phonics skill tracker that helps parents map what their child knows to the right book level, which can simplify this matching considerably.

What does the research say about decodable books for struggling readers and dyslexia?

The research case for decodable texts is strong, especially for children with reading disabilities. A review by Cheatham and Allor, published in Reading and Writing in 2012, found that beginning readers made greater gains when instructed with decodable texts than with predictable texts (books designed to be memorized through pattern and picture cues) ^[2]. The effect was most pronounced for word reading accuracy and phonics application.

Ehri's phase theory of word reading, which underpins most structured literacy programs, explains why: children move through distinct phases of word learning, and the alphabetic phase, where decoding is the primary strategy, is where decodable texts give the most targeted practice ^[1]. Predictable books can undermine this phase by rewarding context guessing over phonics.

The International Dyslexia Association's Knowledge and Practice Standards state that "text used for reading practice should be composed of words that students can decode based on the phonics patterns that have already been taught" ^[5]. That's a direct endorsement of the decodable text principle.

For children with double deficit dyslexia, where both phonological awareness and rapid naming are weak, decodable books are still appropriate but need to be paired with fluency work, because decoding accuracy alone won't build speed. Timed rereading of short decodable texts is one evidence-based technique for that group.

For children flagged with rapid naming deficit, the decodable text gives them a controlled environment to practice without the extra load of unfamiliar vocabulary or complex syntax. Short texts matter here: 8-page books are less tiring than 24-page books.

One honest caveat: most of the strong research compares decodable versus predictable texts as a category. Studies on individual commercial series (Heggerty, BOB Books, and the rest) are thin. The underlying principle is well-supported. The brand-specific claims are less tested.

How should parents use Heggerty decodable books at home?

Using decodable books well at home is mostly about structure and patience. Here's what actually works.

Before the reading session, do 3 to 5 minutes of phonics review. If the book targets the "ai/ay" long vowel pattern, quickly review those patterns with flashcards or a whiteboard before opening the book. This warm-up wakes up the phonics knowledge the book will ask the child to apply. Skipping it is the most common home-use mistake.

During reading, let the child decode. Resist the urge to supply a word fast when they get stuck. Give them 5 to 10 seconds to work it out. If they're still stuck, prompt with the sound, not the word: "What sound does that vowel team make?" This keeps the decoding work with the child instead of training them to wait for rescue.

After reading, do a quick word sort. Write 3 to 5 words from the book on index cards and sort them by pattern. It takes five minutes and improves retention by making the child categorize what they just read ^[1].

Target 10 to 15 minutes per session, 4 to 5 days a week. More is not better for most struggling readers, who tire quickly. Short and consistent beats long and sporadic.

Rereading the same book two or three times on different days builds fluency, which is the bridge between accurate but slow decoding and reading that feels natural. Don't rush to the next book. A child who reads a book accurately once is not done with it.

For high-frequency words that show up in the books, like "the" or "was," point to them directly: "This word is 'the.' We just have to know this one." Don't ask the child to decode it. Heart words are taught directly, not decoded. Mixing the two approaches in one session confuses children about which strategy applies when.

For a broader home reading system, the sight word flashcards and first grade sight words resources complement your decodable book practice by covering the high-frequency irregular words separately.

Can you request Heggerty decodable books through an IEP or 504 plan?

You can request that specific decodable texts be used as part of a child's reading intervention, but how you frame it matters.

Under IDEA (the Individuals with Disabilities Education Act, 20 U.S.C. § 1400 et seq.), the IEP team is responsible for designing a program of specially designed instruction that meets the child's unique needs ^[8]. The law gives parents the right to participate meaningfully in that design. You can bring decodable books to an IEP meeting as a discussion point, especially if your child is getting structured literacy intervention and the school isn't using decodable texts.

The practical move is not to ask for a specific brand by name. Ask instead that the child's reading intervention include "decodable texts aligned to the child's current phonics scope and sequence" as a supplementary aid. That language maps directly to structured literacy best practice and is defensible under IDEA's requirement for evidence-based practices.

The U.S. Department of Education's IDEA guidance confirms that IEP teams must consider "the use of supplementary aids and services" in the general curriculum ^[9]. Decodable books used in intervention can reasonably qualify.

For a 504 plan under Section 504 of the Rehabilitation Act, accommodations are generally procedural (extra time, preferential seating) rather than instructional, so requesting a specific type of reading text is a harder argument under 504 than under IDEA ^[12]. If your child qualifies for special education, the IEP route gives you more room.

Working through these conversations with a school gets easier when you understand your child's current assessment profile. Resources on learning disability test and signs of dyslexia help you build the factual foundation for an IEP request.

Are there free alternatives to Heggerty decodable books?

Yes, and some of them are excellent.

The University of Florida Literacy Institute (UFLI) offers free decodable text PDFs that parents can download and print at home ^[3]. The UFLI Foundations decodable texts are rigorous, carefully controlled for phonics sequence, and updated regularly. They're not as visually polished as commercial books, but the content quality is high and the price is right.

Flyleaf Publishing has a free decodable book series available for limited use through their website. The quality is good, and some titles have been adopted by state literacy programs.

SpellingCity and Starfall both have online decodable reading activities that are free or low-cost, though they're interactive rather than physical books.

For families who want physical books cheaply, BOB Books are widely available in public libraries and at used book stores. They're not aligned to Heggerty's sequence, but they cover the early CVC and blend stages well and are often the easiest decodable books to find through a library.

A note on printing costs: if you print the UFLI decodables at home, even in black and white, a set of 30 to 40 books can cost $15 to $25 in paper and ink. That's still far cheaper than buying retail decodable books. If you have access to a school or library printer, ask whether you can print a personal-use set.

Used-book marketplaces (ThriftBooks, eBay, Facebook Marketplace) often have decodable book lots for a fraction of retail. A set of 15 Heggerty decodable books in good condition might run $20 to $40 used versus $80 to $100 new.

Frequently asked questions

What grade level are Heggerty decodable books designed for?

Heggerty decodable books are primarily designed for kindergarten through second grade, covering the foundational phonics stages from simple CVC words through multisyllabic patterns. They're also appropriate for older students in intervention if those students are still working on early phonics skills. Grade level is less relevant than phonics level: match the book to the patterns the child has actually been taught, not their age.

Do Heggerty decodable books work for children with dyslexia?

Yes, decodable books are a core tool in structured literacy intervention for dyslexia. The International Dyslexia Association recommends that reading practice text be composed of words decodable with patterns already taught. Heggerty's books follow that principle. They work best when paired with explicit, systematic phonics instruction rather than used in isolation. A qualified reading specialist or educational therapist should guide the overall intervention plan.

How many Heggerty decodable books are there in the series?

As of 2025, Heggerty's decodable book series includes multiple sets organized by phonics level, with each set containing several individual titles. The exact count varies by product line and grade band. Heggerty periodically adds to the series, so check heggerty.com directly for the current catalog. School sets typically include 6 copies of each title for small-group instruction.

Can I find Heggerty decodable books at my local library?

Maybe. Heggerty's decodable books are newer than some competing series, so library stock varies widely by region. Search your library's catalog, ask the children's librarian to request them through interlibrary loan, or ask your school district's curriculum office about borrowing from classroom sets. If Heggerty books aren't available, BOB Books and UFLI free decodables are solid alternatives that are more accessible through libraries and free downloads.

Are Heggerty decodable books the same as the Heggerty phonemic awareness curriculum?

No, they're separate products. The Heggerty phonemic awareness curriculum is a daily oral lesson program focused on sound manipulation (blending, segmenting, rhyming) without print. The decodable books are a printed text series designed to give children practice reading words with phonics patterns they've already been taught. They're meant to complement each other, but they're sold separately and serve different instructional purposes.

What is the price range for Heggerty decodable books?

Individual Heggerty decodable books typically cost $4 to $7 at retail. School classroom sets can run $150 to $300 per level. For home use, buying 10 to 15 targeted books covering your child's current phonics range costs roughly $50 to $80 new. Used copies on resale platforms can cut that cost in half. Free alternatives like UFLI decodables can reduce spending to near zero if you print at home.

How do Heggerty decodable books differ from leveled readers like Guided Reading books?

Guided reading leveled books (like Fountas and Pinnell levels) are leveled by overall text difficulty and are designed for children to use meaning, syntax, and visual cues together. Decodable books like Heggerty's are leveled by phonics pattern and restrict text to words the child can fully decode. Research shows decodable texts better support early phonics development, especially for struggling readers, while leveled readers can accidentally encourage guessing over decoding.

Can I use Heggerty decodable books if my child's school uses a different phonics program?

Yes, with attention to alignment. The phonics patterns in Heggerty decodable books are standard patterns that appear in most structured literacy programs. Compare the target pattern of each Heggerty book to what your child has already been taught in their current program. As long as the book's target patterns have been explicitly taught, the mismatch risk is low. When in doubt, ask your child's reading teacher or tutor to check a sample book against their scope and sequence.

How long should a child spend reading Heggerty decodable books each day?

Ten to fifteen minutes per session, four to five days a week, is a reasonable target for most early readers. Short sessions work better than long ones for struggling readers who fatigue quickly. Rereading the same book multiple times across several days builds fluency and is more valuable than rushing through new books. Pair each session with a brief 3 to 5 minute phonics warm-up before opening the book for best results.

Are Heggerty decodable books evidence-based?

The principle behind them, using decodable texts aligned to explicit phonics instruction, is well-supported by reading research, including work by Cheatham and Allor (2012) and Ehri's phase theory of word reading. The What Works Clearinghouse had not independently reviewed the Heggerty decodable book series as of mid-2025. The phonemic awareness curriculum from Heggerty has some supporting evidence, but brand-specific efficacy data for the decodable books is limited.

Can I request that my child's school use decodable books in their IEP?

Yes. Under IDEA (20 U.S.C. § 1400), IEP teams must design specially designed instruction based on the child's needs, and parents have the right to participate in that design. Request that reading intervention include decodable texts aligned to the child's current phonics scope and sequence. Framing it as a category of instructional material rather than a specific brand is more likely to be accepted and is consistent with evidence-based structured literacy practice.

Do Heggerty decodable books include high-frequency irregular words?

Yes, they include a small number of explicitly taught high-frequency words, sometimes called heart words, that don't fully follow decodable patterns (like 'the,' 'was,' 'said'). These are introduced directly as words children need to recognize, not decoded by phonics rules. A well-designed decodable book introduces only the irregular words that have been explicitly taught, keeping the guessing load very low for early readers.

What should I do if my child finds the Heggerty decodable books too hard or too easy?

If they're too hard, the book's phonics level is ahead of what the child has been taught. Drop back to an earlier set that matches mastered patterns. If they're too easy, either advance to the next set or move to less controlled connected text for fluency practice. A good rule of thumb: a book is at the right level if the child reads it with 90 to 95 percent accuracy on a first read. Below 90 percent accuracy, the text is too hard.

Is Heggerty the same as Heggerty Bridge?

Heggerty Bridge is a separate product from the same company, designed as a phonics program that bridges phonemic awareness to print. It is a structured phonics curriculum product, distinct from both the original phonemic awareness daily lessons and the standalone decodable book series. If your school mentions Heggerty Bridge, they're referring to that specific curriculum program rather than just the decodable books.
