What are the signs of dyslexia by age?

In kindergarten and 1st grade (ages 5-7), look for difficulty rhyming, learning letter sounds, and remembering sequences. In 2nd-3rd grade (ages 7-9), watch for slow reading, frequent guessing, and avoiding reading aloud. In 4th-6th grade (ages 9-12), signs include difficulty with comprehension, spelling, and written expression. In middle school and beyond, look for slow reading speed, difficulty with foreign languages, and avoidance of reading-heavy tasks.

My child was tested by the school and came back fine. Can they still have dyslexia?

Yes. School evaluations often use screening tools that measure broad academic skills rather than the specific phonological processing deficits that define dyslexia. Schools may also use a discrepancy model that misses children who compensate well. A private dyslexia-specific evaluation uses targeted assessments like the CTOPP-2 to measure the underlying processing skills.

Can dyslexia be cured?

Dyslexia is a neurological difference, not a disease, so it cannot be cured. However, with proper intervention using structured literacy approaches like Orton-Gillingham, children can develop strong reading skills and effective strategies. Early intervention produces the best outcomes. The brain builds new neural pathways for reading, but the underlying difference in processing remains.

What is the difference between a dyslexia screening and a full evaluation?

A screening is a quick check that identifies risk for dyslexia. It takes about 15-30 minutes and tells you whether further testing is recommended. A full evaluation is a comprehensive diagnostic assessment lasting 2-4 hours that measures phonological processing, rapid naming, reading fluency, comprehension, and more. It provides a formal diagnosis and specific recommendations for intervention and school accommodations.

What is the difference between dyslexia and ADHD?

Dyslexia is a specific learning disability affecting reading, spelling, and phonological processing. ADHD is an attention disorder affecting focus, impulse control, and executive function. About 30-40% of children with dyslexia also have ADHD. The key difference: a child with ADHD can decode words but may lose focus while reading, while a child with dyslexia struggles with the actual decoding process regardless of attention.

Does my child need an IEP or a 504 plan for dyslexia?

An IEP provides specialized instruction and is appropriate when your child needs specially designed teaching methods (like Orton-Gillingham). A 504 plan provides accommodations like extended time and audiobooks but no specialized instruction. If your child needs a different way of being taught to read, push for an IEP. If they can access the curriculum with accommodations alone, a 504 may be sufficient.

How do I request a dyslexia evaluation from my school?

Submit a written request (email or letter) to your school principal or special education coordinator specifically asking for an evaluation for a suspected specific learning disability in reading. Keep a copy. The school has 60 days to respond. If they refuse, they must provide Prior Written Notice explaining why. You have the right to an Independent Educational Evaluation at the school's expense if you disagree with their findings.

How much does dyslexia testing cost?

Private dyslexia evaluations typically cost a comprehensive evaluation-$5,000 depending on the provider and scope. At Dyslexia Evaluations, we offer free screenings and comprehensive evaluations for a comprehensive evaluation. School-based evaluations are free but may not specifically test for dyslexia. Some insurance plans cover neuropsychological testing, though coverage varies.

Response to Intervention (RTI) and Dyslexia: A Parent’s Guide

What Is Response to Intervention (RTI)?

Response to Intervention (RTI) is a system schools use to help struggling students before deciding whether they need special education. When your child falls behind in reading, the school provides targeted support, tracks progress closely, and adjusts the help based on how your child responds. It is a support framework, not a diagnosis.

RTI is built on a simple idea: catch reading problems early and act on them fast. Instead of waiting for a child to fail year after year, teachers use regular screening and data to spot who needs extra help. That help is layered, meaning it gets more intensive if a child continues to struggle.

For parents of a child who may have dyslexia, RTI matters a great deal. It is often the first place a reading problem shows up, and it can be either a bridge to the right help or an unintended roadblock. Understanding how it works puts you in a much stronger position to advocate for your child.

How Does RTI Work? The Three Tiers Explained

RTI usually has three tiers of support that increase in intensity. Tier 1 is high-quality instruction for every student in the classroom. Tier 2 adds small-group help for students who need more. Tier 3 provides intensive, often one-on-one intervention. A child moves between tiers based on how they respond to each level of support.

Think of the tiers as a staircase. Most children do fine at the bottom step. A smaller group needs the middle step, and only a few need the most intensive support at the top.

Tier 1: Core Classroom Instruction

Every student receives Tier 1. This is the general reading curriculum taught to the whole class, ideally using methods backed by research. Schools screen all students a few times a year to see who is on track. If your child is keeping pace, Tier 1 may be all they need. If not, the school should move them to Tier 2.

Tier 2: Targeted Small-Group Support

At Tier 2, your child gets extra reading help in a small group, usually a few times a week on top of regular instruction. The focus is on specific skills, such as phonics or decoding. Teachers collect data to see whether the child is catching up. This tier typically lasts several weeks before the team reviews progress.

Tier 3: Intensive Intervention

Tier 3 is the most intensive level, often delivered one-on-one or in very small groups with a specialist. Sessions happen more frequently and target the exact skills a child is missing. If a child still struggles after strong Tier 3 support, that is a strong signal the school and family should look deeper, including a comprehensive evaluation for dyslexia.

RTI and Dyslexia: Where the Two Connect

RTI and dyslexia intersect because reading is exactly where dyslexia shows up first. A child with dyslexia often struggles with the phonics and decoding skills that RTI is designed to strengthen. Their pattern of slow or limited response to good reading instruction is one of the clearest early signs that dyslexia could be present.

Dyslexia is a language-based learning difference that makes it hard to connect letters to sounds. Because RTI closely monitors how children respond to reading instruction, it can surface these struggles earlier than a family might notice at home.

According to the International Dyslexia Association, dyslexia is the most common learning disability, and research suggests it affects as many as 15 to 20 percent of the population to some degree. That means in almost every classroom, several children are wired to find reading harder than their peers. RTI data often catches these children first, which is why the framework and dyslexia are so closely linked.

The key insight for parents is this: a child who needs Tier 2 or Tier 3 reading help, and who does not catch up the way peers do, deserves a closer look. If you are noticing struggles at home too, a professional dyslexia evaluation can tell you what is really going on beneath the reading trouble.

Can RTI Diagnose Dyslexia?

No. RTI cannot diagnose dyslexia. RTI is a system for delivering and monitoring reading support, not an assessment tool. It can flag that a child is struggling and show how they respond to help, but only a comprehensive evaluation by a qualified professional can identify dyslexia.

This distinction confuses many families, and understandably so. Because RTI generates so much reading data, it can feel like a diagnostic process. It is not. RTI answers the question "Is this child responding to instruction?" It does not answer "Why is this child struggling?"

A comprehensive dyslexia evaluation looks at areas RTI does not measure, including phonological processing, rapid naming, working memory, and the gap between a child's reading ability and their overall thinking skills. These pieces together can reveal a pattern that is consistent with dyslexia, something a tier of small-group reading practice simply cannot show.

The Hidden Risk: How RTI Can Delay a Dyslexia Diagnosis

The biggest risk of RTI is that it can be used, intentionally or not, to postpone a formal evaluation. Some schools keep children cycling through tiers for months or even years, saying they need to "wait and see" before testing. This delay can cost a child critical time during the years when reading intervention works best.

RTI was designed to help children faster, but in practice it sometimes does the opposite. When a school treats each tier as a hoop to jump through before considering an evaluation, a child can lose a year or more of specialized help.

Timing matters enormously with reading. The National Institute of Child Health and Human Development has long emphasized that early, intensive reading intervention produces the strongest results, and that struggles left unaddressed tend to compound over time. A child who waits until fourth grade for the right help faces a steeper climb than one identified in first grade.

Here is what parents should hold onto: RTI and a formal evaluation are not an either-or choice. Your child can receive tiered reading support and be evaluated at the same time. You do not have to finish the RTI process before requesting testing. Families who understand this often avoid the trap described in our article on why schools miss dyslexia and what to do instead.

What Effective Reading Intervention Should Look Like

Effective reading intervention for a child who may have dyslexia is structured, explicit, and multisensory. It directly teaches the relationship between sounds and letters in a systematic order, gives lots of practice, and is delivered by a trained instructor. Generic reading help or simply "more reading time" is usually not enough.

Not all RTI is created equal. A child can sit in a Tier 2 group all year and still not improve if the instruction does not match how they learn. For struggling readers, the research points clearly toward structured literacy approaches.

Structured Literacy and Orton-Gillingham

Structured literacy, including approaches based on the Orton-Gillingham method, teaches reading explicitly and sequentially. Children learn letter sounds, blending, and spelling patterns step by step, with each skill building on the last. Lessons often engage sight, sound, and touch at once, which helps the brain form stronger connections.

Signs the Intervention Is Working

Good intervention shows measurable progress. Ask to see the data. Is your child's reading fluency improving week to week? Are they decoding words they could not before? If progress is flat after weeks of solid Tier 2 or Tier 3 support, that is important information, not a reason to keep waiting. It often points toward the need for a full evaluation.

Your Rights: RTI Cannot Legally Delay an Evaluation

Under federal law, a school cannot require a child to complete the entire RTI process before evaluating them for special education. Parents have the right to request a formal evaluation in writing at any time, and the school must respond. RTI data can be part of an evaluation, but it cannot be used to block one.

This is one of the most important things a parent can know. The Individuals with Disabilities Education Act includes a principle often called "child find," which requires schools to identify and evaluate children who may have a disability. RTI does not override that duty.

If you believe your child needs testing, you can send a written request to the school asking for a comprehensive evaluation. Put the date on it and keep a copy. Once you make that request, the school is generally required to respond within a set timeline rather than simply pointing you back to the next RTI tier.

Understanding these protections helps you use tools like a 504 plan or an IEP built from your child's evaluation once a need is identified. You can also learn more about how the process fits together on our questions and answers page.

Questions to Ask Your Child's School About RTI

When your child is in RTI, ask specific questions that keep the process transparent and moving. Find out which tier your child is in, what intervention is being used, how often it happens, and what the progress data shows. Clear answers protect your child from getting stuck in a slow-moving cycle.

Coming to a meeting with focused questions signals that you are paying attention and expect results. Consider asking:

Which tier is my child in, and how long have they been there? This tells you how much time has already passed.

What specific reading program or method are you using? You want to hear about a structured, research-based approach, not vague "extra help."

How often and how long are the sessions, and who delivers them? Intensity and instructor training matter.

What does the progress data show? Ask to see the actual numbers over time, not just a general impression.

At what point will you recommend a full evaluation? A reasonable answer includes a timeline, not an open-ended "we'll see."

If the answers are vague or the timeline keeps stretching, that is your cue to request an evaluation in writing.

How Parents Can Support Reading at Home

Parents can reinforce reading intervention at home with short, consistent, low-pressure activities. Read aloud together, play with rhymes and sounds, practice letter sounds, and celebrate effort over perfection. Home support does not replace professional help, but it strengthens skills and protects your child's confidence.

You do not need to be a reading specialist to make a difference. Small daily habits add up, and they keep reading from becoming a source of stress in your home.

Try reading aloud to your child even after they can read on their own, since it builds vocabulary and a love of stories. Play sound games in the car, like naming words that rhyme or breaking words into their sounds. Keep practice sessions short so they end before frustration sets in. Most of all, praise the effort your child puts in, because children with reading struggles are especially vulnerable to feeling "dumb" when they are anything but.

There are many practical reading strategies you can start using tonight, from paired reading to simple sound games, and the effort you put in at home genuinely matters.

Frequently Asked Questions

How long should a child stay in RTI before getting evaluated?

There is no fixed rule, but a child should not spend an entire school year cycling through tiers without progress and without anyone raising the possibility of an evaluation. If your child has had weeks of solid Tier 2 or Tier 3 support and the data is flat, it is reasonable to request a comprehensive evaluation right away. You do not have to wait for RTI to finish.

Is RTI the same as special education?

No. RTI is general education support available to any struggling student, and it does not require a formal diagnosis. Special education is a legally protected service for children identified with a disability through evaluation. A child can be in RTI without being in special education, and RTI is not a substitute for the evaluation that leads to an IEP.

Can my child do RTI and get a private evaluation at the same time?

Yes. Many families pursue a private evaluation while their child continues to receive tiered reading support at school. A private evaluation can move faster than a school timeline and gives you clear, independent answers, and you can book one online at your convenience. The results can then inform the school's plan, whether that becomes a 504 plan or an IEP. Our screening is free, and a full comprehensive evaluation is $2,200, available in Madison, WI and nationwide by secure video.

What if the school says my child is "too smart" to have dyslexia?

Being bright and having dyslexia often go together. Dyslexia is not related to intelligence, and many capable children work twice as hard to keep up, masking their struggle. If your instinct says something is off, trust it. A comprehensive evaluation looks past classroom impressions and measures the specific skills involved in reading.

Does RTI work for every struggling reader?

RTI helps many children, especially those who simply need more practice or slightly different instruction. But for a child with dyslexia, generic tiered support is often not enough on its own. These children usually need structured, explicit reading intervention plus, in many cases, formal identification so their support can be protected and tailored over time.
