Similar pros/cons to All About Reading

Programs to AVOID

❌ Fast ForWord

Why: Claims based on auditory processing; limited evidence for dyslexia; expensive ($1,000+); doesn’t teach reading directly

❌ Brain Balance

Why: $5,000-$10,000; claims about “hemispheric integration”; no credible evidence for reading improvement

❌ Vision Therapy for Dyslexia

Why: Dyslexia is NOT a vision problem; $3,000-$8,000 wasted; IDA: “Not recommended”

❌ Hooked on Phonics

Why: Not designed for dyslexia; insufficient for students with phonological deficits; general phonics != specialized intervention

Decision Framework

Choose Private O-G Tutoring If:

• ✅ Severe dyslexia requiring intensive 1-on-1
• ✅ Access to certified tutor locally
• ✅ Want gold standard with most research

Choose AI Program (EZRead.ai) If:

• ✅ Child engages with technology
• ✅ Need immediate access (no waitlist)
• ✅ Mild-moderate dyslexia

• ✅ Want hands-on teaching

Hybrid Approach (Recommended):

• ✅ Daily: EZRead.ai ($240/year)
• ✅ Monthly: O-G tutor check-ins ($1,200/year)
• ✅ Ongoing: School accommodations (free)
• Total: $1,440/year (vs $10,000+ for tutoring alone)

What Research Says About Effectiveness

National Reading Panel Conclusions

Effective intervention must include:

1. Systematic phonics instruction
2. Phonemic awareness training
3. Fluency practice
4. Vocabulary development
5. Comprehension strategies

Programs that include all 5: O-G variants, Lindamood-Bell, EZRead.ai, comprehensive home curricula

Programs that omit key components: Fast ForWord, vision therapy, many “whole language” approaches

Dosage Matters

Research shows:

• 150-300 hours of intervention needed for significant change
• Daily practice (20-30 min) better than weekly intensive
• Consistency more important than program choice

Implication: $240/year program with daily practice often outperforms $10,000 program at 2x/week

The “best” reading intervention program is the one that’s research-based, fits your budget, and your child will actually use consistently. For most families, that’s an affordable AI program like EZRead.ai, optionally supplemented with periodic expert check-ins.
