Hannah’s Reading Room
At Hannah’s Reading Room, I provide personalized, one-on-one reading intervention for students who struggle with reading, dyslexia, spelling, and comprehension. My goal is to help every child become a confident, successful reader by identifying the root of their reading difficulties and providing explicit, evidence-based instruction tailored to their individual needs. What sets me apart from many tutors is my specialized training and credentials. I am a Certified Educational Reading Interventionist (CERI) and hold a Master’s degree in Literacy with a Dyslexia Endorsement from an International Dyslexia Association (IDA)-accredited program. My instruction is grounded in the Science of Reading and incorporates research-based programs, including Lindamood-Bell® LiPS, Seeing Stars, and Visualizing & Verbalizing. At Hannah’s Reading Room, you’re not just hiring a tutor, you’re partnering with a reading specialist dedicated to helping your child achieve lasting success.
The Reading & Math Clinic
The Reading & Math Clinic specializes in providing individualized reading and/or math intervention for struggling learners who are below grade level in these skills. We utilize LIPS with Seeing Stars support and Math U See curricula; both programs entail systematic, explicit, multi-sensory instruction for students who do not respond to traditional instructional methods. We have had significant success with learners of all backgrounds, including those with dyslexia, dysgraphia, dyscalculia, autism, ADHD, and speech and hearing deficits. To get started, schedule a free screening and consultation to determine if enrolling in our program is the right fit for you. Students typically attend 3-5x a week for 1-2 hour one-on-one lessons with our trained specialists. Lesson frequency varies based on individual need. Parents are debriefed after each lesson and provided with recommendations for home practice. Students also receive a homework folder to encourage home practice. Parents are always welcome to sit in on lessons to inform their home practice. Students often improve in one or more foundational reading skill by one or more grade level in the first 40 hours of treatment. Our reading program takes about 80-120 hours to complete overall. Students complete testing every 40-50 hours to provide parents with detailed progress updates and recommendations for next steps. We collaborate closely with parents to establish a graduation date once all skills are at or above grade level.
If your child is a struggling reader, you will hear three names within a week of starting your research: Orton-Gillingham, Wilson, and Barton. Parents usually assume they're competing products. They aren't. Orton-Gillingham is the methodology; Wilson and Barton are two of the programs built on it, along with Lindamood-Bell, All About Reading, Logic of English, and a dozen others.
The real question isn't "which program is best." It's who is delivering the instruction, how well trained are they, and how much structure do you personally need. This guide answers that, with Arizona pricing and ESA coverage for each option.

The short answer
| If you... | Choose |
|---|---|
| Are hiring a trained tutor and want maximum flexibility | Orton-Gillingham (IMSE, IDA-accredited, or AOGPE-trained practitioner) |
| Want to teach your own child with a fully scripted program | Barton Reading & Spelling |
| Are coming out of a public school that used it, or want a school-standard credential | Wilson Reading System |
| Have a child who can't hold sounds in memory or can't visualize what they read | Lindamood-Bell (LiPS, Seeing Stars, Visualizing & Verbalizing) |
| Have a typical early reader, no red flags | A systematic phonics curriculum — you don't need any of the above |
What they actually are
Orton-Gillingham (OG) is not a boxed curriculum. It's an instructional approach — explicit, systematic, cumulative, multisensory, diagnostic — developed in the 1930s and validated repeatedly by Science of Reading research since. An OG practitioner builds each lesson from the child's error patterns. That flexibility is its strength and its risk: OG is only as good as the person delivering it, and "OG training" ranges from a weekend workshop to a two-year fellowship. Read our full Orton-Gillingham curriculum guide for the method's structure.
Wilson Reading System is an OG-derived, highly structured program built for intensive intervention with students in grade 2 and up. It's the program most Arizona public school reading specialists are trained in, so it's common among tutors with a district background. Wilson Level I and Level II certifications are real, verifiable credentials with supervised practicum hours behind them.
Barton Reading & Spelling is a scripted, ten-level OG program specifically designed so that a non-specialist — a trained parent, a paraprofessional, a tutor — can deliver it faithfully. Every word the instructor says is written down. Susan Barton built it for exactly the family that can't find or can't afford a certified practitioner.
Lindamood-Bell is a different animal. LiPS targets phoneme awareness at the mouth-movement level, Seeing Stars builds orthographic memory, and Visualizing & Verbalizing builds comprehension. It's the right call when decoding instruction alone hasn't moved the needle.
Head-to-head comparison

|---|---|---|---|
| Type | Methodology | Scripted program | Scripted program |
| Who delivers it | Trained practitioner | Certified teacher or tutor | Parent or tutor |
| Training required | Weekend to 2-year fellowship | Level I / Level II certification | Free online tutor training videos |
| Best starting age | 5+ | 7+ (grade 2 and up) | 5+ |
| Upfront materials cost | Practitioner supplies materials | Program kits, tutor-purchased | ~$250–$350 per level, 10 levels |
| Typical AZ hourly rate | $60–$110 | $65–$110 | $50–$85 |
| Flexibility | Highest — fully diagnostic | Moderate — fixed sequence | Lowest — fully scripted |
| Parent-led viable? | Not without training | Rarely | Yes, by design |
| ESA-eligible in Arizona | Yes (tutoring) | Yes (tutoring) | Yes (tutoring and the kits as curriculum) |
Cost reality in Arizona
Twice-weekly tutoring at $75/hour runs about $650 a month, or roughly $6,000–$7,000 for a full year of intervention. Parent-led Barton across all ten levels totals roughly $2,500–$3,500 in materials — and levels resell well, which is why used Barton kits move fast in Arizona homeschool groups.
Arizona ESA covers both paths. Tutoring is an approved expense; Barton kits are approved as curriculum and materials. See what Arizona ESA covers and the ClassWallet direct pay vs. reimbursement guide for how payment actually works.
Which one for which child
A 6-year-old who reverses letters and can't blend sounds. Any of the three works. Cost decides it: Barton parent-led is by far the cheapest, and this age responds well to a scripted program.
A 9-year-old two grades behind, already frustrated. Hire a trained OG or Wilson practitioner. At this age the child is fighting years of failure experience, and a diagnostic tutor who can adjust in the moment beats a script. Do not attempt parent-led remediation with a child who has started refusing.
A 13-year-old who decodes badly and can't spell. Wilson, specifically — it was designed for older students and doesn't use materials that read as babyish. Wilson is the least likely to embarrass a teenager.
A child who decodes fine but retains nothing. Not a decoding problem. Look at Lindamood-Bell's Visualizing & Verbalizing, or an educational therapist.
What a good practitioner looks like, regardless of program
- Names their training program and hours without hedging.
- Screens before session one — decoding, phonemic awareness, fluency.
- Recommends two to three 45–60 minute sessions per week, not one.
- Measures progress with nonsense-word decoding and spelling inventories every 6–12 weeks.
- Gives you a realistic timeline: gains in 8–12 weeks, grade level in 1–3 years.
- Handles ClassWallet or provides compliant itemized invoices.
Anyone promising two grade levels in a summer is selling.
Frequently Asked Questions
Is Wilson better than Orton-Gillingham? Wilson is an Orton-Gillingham program, so the comparison isn't apples to apples. Wilson is more structured and more standardized; a skilled independent OG practitioner is more adaptive. For students in grade 2 and up who need heavy structure, Wilson is excellent. For younger children or unusual profiles, flexible OG usually wins.
Is Barton as effective as hiring an Orton-Gillingham tutor? For a motivated parent with a cooperative child, Barton delivered faithfully gets results comparable to tutor-led OG, because the script preserves the method's fidelity. It falls apart when the parent-child relationship is already strained by reading, or when the parent can't commit to two sessions a week for two years.
Can I switch programs mid-stream? Yes, but finish the current level or book first. Switching mid-sequence leaves gaps in the scope and sequence, which is exactly the problem structured literacy exists to solve. If you switch, have the new practitioner re-screen and place from scratch.
Does Arizona ESA pay for Barton kits? Yes. Curriculum and materials are ESA-eligible, and Barton levels are purchased as curriculum. Many Arizona families buy levels one at a time through ClassWallet as their child progresses.
How do I verify an Orton-Gillingham certification? Ask for the training provider's name (IMSE, AOGPE, Wilson, an IDA-accredited university program), the completion year, and whether it included a supervised practicum. AOGPE and Wilson both publish practitioner directories you can check directly.
Do we need a dyslexia diagnosis before starting any of these? No. All three methods are safe and effective for any struggling reader, diagnosed or not. A diagnosis matters for accommodations and SAT/ACT extended time later, not for starting instruction now.
