Slingerland Method

The Slingerland Method is a classroom adaptation of Orton-Gillingham for general first-through-fourth-grade instruction. In our assessment, it is most useful for students at risk for dyslexia. It is taught principally through certified teachers rather than purchased as a boxed curriculum.

Who the publisher is

The Slingerland Method is an adaptation of the Orton-Gillingham remedial approach for classroom use. The Slingerland Institute, now the Slingerland Literacy Institute, has trained over 16,000 teachers according to its published figures.

The Institute's mission is explicitly teacher-facing rather than parent-facing. Its primary offerings are certification courses, multi-week intensive trainings that certify instructors at two levels: Certified Slingerland Teacher (CST) and Certified Slingerland Intervention Teacher (CSIT). The Institute does not publish a self-guided homeschool kit in the manner of All About Reading or Logic of English. Families using the Slingerland Method can (a) hire a certified tutor, (b) enroll a child in a Slingerland-model private school, or (c) complete the certification training themselves to teach their own child.

In our assessment, the method's place in the homeschool market is distinctive: it is reached through a professional rather than a retailer. This shapes almost every aspect of how the method reads on a homeschool rubric.

The core pedagogy

Slingerland teaches reading, spelling, writing, and handwriting as one integrated subject. Students learn phonograms, decoding patterns, and spelling rules in a prescribed sequence, with each lesson cycling simultaneously through visual (seeing the letter), auditory (hearing and producing the sound), and kinesthetic (tracing and writing the letter) channels. This triple-channel reinforcement is the heart of Orton-Gillingham and its derivatives.

A typical daily lesson has three parts. A written-recall portion opens the session: the teacher dictates previously taught phonograms and patterns, and the student writes them while saying the sounds aloud. A learning-of-new-material portion follows: the teacher introduces a new phonogram, rule, or pattern explicitly, with a specified script. A reading-application portion closes: the student reads from a connected text using the accumulating skills. Across grades 1 through 4, the sequence moves from single-letter phonograms through multi-letter graphemes, into syllable types, and eventually into morphology.

Signature mechanics: (1) Simultaneous multisensory encoding, the student never sees, says, or writes a phonogram in isolation; every encounter combines all three channels. (2) Teacher-driven pacing with prescribed sequence, unlike programs that allow the student to set pace, Slingerland moves at a rate the certified teacher calibrates to the student's mastery of prior material. (3) Handwriting as part of the reading program, handwriting is not a separate subject but a channel through which reading is taught, using specific manuscript and cursive letter formations.

What they do exceptionally well

Evidence base for students with reading difficulties. The Slingerland approach has decades of classroom data supporting its use with first-through-fourth-grade students at risk for dyslexia. For a family whose child has been evaluated and shown to have a specific language-based learning difference, the method is, in our assessment, among the most defensible options available.

Integration of handwriting, spelling, and reading. Slingerland collapses the three into one instructional stream. This can be more efficient for the student once the method is running well.

Professional infrastructure. The certification pathway provides two recognized credentials (CST and CSIT), a tutor directory, and a nationwide network of Slingerland-model schools.

What they do poorly

Not designed for unsupported parent implementation. The method assumes a trained teacher in the room. A parent working from the manual without training can get some benefit, but the gap between trained-delivery and cold-read delivery is large. This is honest of the Institute, they do not market the method as a self-teaching kit, and families need to set expectations accordingly.

Training is a significant time and cost investment. Slingerland certification courses run multi-week intensives with substantial fees. A parent who completes certification solely to teach their own child is making a meaningful investment that is harder to justify than picking up a parent-friendly boxed program.

Materials can feel austere. Next to the visual polish of All About Reading or Logic of English, Slingerland materials look like what they are: professional reference tools for trained teachers, not consumer curricula designed to delight a parent browsing at a convention.

Who it fits / who it doesn't

• Pick the Slingerland Method if: your child has been evaluated for or shows signs of dyslexia; you can hire or access a certified Slingerland tutor; you value research-backed multisensory instruction delivered with fidelity; you're prepared to pursue certification yourself if you plan to teach the program without a tutor; you have tried other phonics programs and they have not worked.

• Skip the Slingerland Method if: your child reads easily and you want a straightforward mainstream phonics program; you want a consumer-friendly boxed curriculum you can open and begin using immediately; you are looking for digital delivery or self-paced video lessons; you live in an area without a certified tutor and cannot invest in certification training.

Cost honest assessment

Slingerland method manuals and materials are moderately priced; the primary cost is the training. Per the Slingerland Institute, certification courses vary in length and price, with intensive summer courses typically running several weeks. A family hiring a certified Slingerland tutor should expect hourly rates comparable to other credentialed reading specialists, commonly $60–$120 per hour in April 2026, varying by region. At three to five sessions per week, annual tutoring cost can run into four or five figures.

Compared to Barton Reading & Spelling System, a more homeschool-friendly Orton-Gillingham-aligned program designed for parent implementation without certification, Slingerland is costlier in time and training but has a stronger classroom-delivered evidence base. Compared to Wilson Reading System, another OG-aligned intervention model, Slingerland is similarly professional in orientation.

ESA eligibility notes

When Slingerland is delivered as private tutoring rather than purchased curriculum, its ESA treatment depends heavily on the state program. Some states permit ESA reimbursement for tutoring by credentialed providers in specific circumstances, families in states like Arizona and West Virginia should verify with their program administrator whether certified reading-intervention tutoring qualifies as an approved expense. The Slingerland Institute's printed materials, when purchased directly, may be categorized as educational materials under more flexible ESA rules. Families should document the provider's certification status when submitting for reimbursement.

Alternatives

• Barton Reading & Spelling System, a family would pick Barton over Slingerland because Barton is specifically designed for homeschool parent delivery without certification and comes in a boxed video-training format.
• All About Reading, a family would pick All About Reading over Slingerland because AAR is Orton-Gillingham-informed, parent-friendly, and priced as a consumer curriculum rather than a professional training.
• Wilson Reading System, a family would pick Wilson over Slingerland if they already have access to a Wilson-certified specialist through a school system or private practice.
