ACT Prep for Students with Dyslexia

Read time: 12 min  ·  Last updated: June 27, 2026

A dyslexia diagnosis changes ACT prep in a meaningful way, but discerning your son or daughter has dyslexia can be a huge challenge. If you suspect your son or daughter might have dyslexia, please read through this article. It combines some tips from the ACT that can help direct you to the proper resources for a diagnosis. If your son or daughter is struggling on the reading test but you don't know why, seriously consider reading this passage. If they don't have dyslexia, then you can move on to more allistic test prep. But dyslexia is seriously underdiagnosed in the US according to several reliable sources, and my own personal experience.

If you already know your son or daughter has dyslexia, the accommodations portion of this article may be specifically interesting to you. If your son or daughter needs accommodations, he or she should get them on the test. A lot of students don't want to feel different. I've walked through the accommodations process specifically for dyslexia below. Knowing what the process looks like can help alleviate some fear of the unknown, and hopefully help your son or daughter get the help he or she needs and deserves.

Finally, I've included dyslexia-specific test prep tips at the bottom of this article. There are some things that work for most students on several sections of the test, and they work even better for a student with dyslexia. Please let me know if you have any questions or want more information on any subject.

Is dyslexia underdiagnosed?

According to the Yale Center for Dyslexia & Creativity, 20% of the world's population is dyslexic. That number is widely quoted, but peer reviewed articles attribute global dyslexia numbers to between 5-20%.

On the more conservative side, 5% of the population having dyslexia would mean that 1 in 20 people have dyslexia. A typical American high school of 1,500 students has 75 dyslexic kids by that floor. A 30-student honors English class has at least one or two. Can you name all 75 dyslexic kids at your child's high school? Do you think the kids themselves know they're dyslexic? I'd argue the diagnosis rates are falling way behind the actual prevalence rates for a variety of reasons this article will explore.

Then, we will talk about the accommodations available for students with diagnosed dyslexia. There are several on the ACT that are genuinely helpful. Then, I'll lay out an ACT prep plan and strategies designed specifically for students with dyslexia.

What is Dyslexia?

Dyslexia is, by federal definition, an unexpected difficulty in reading for someone with the intelligence to be a much better reader. The score gap dyslexic students face on the ACT is not a comprehension problem. It's a decoding-speed-meets-pacing problem.

Federal law defines dyslexia as "an unexpected difficulty in reading for an individual who has the intelligence to be a much better reader."

The Yale Center for Dyslexia & Creativity's Sally Shaywitz, the field's most authoritative researcher, describes the condition as "slow reading, fast thinking."

The problem with ACT prep for dyslexic students is: the test is reading-heavy and timed, so it constrains the channel through which a dyslexic student's actual reasoning gets measured. Open that channel and the score follows. But many parents don't understand that their child is dyslexic because their child probably doesn't understand it themselves.

Stealth dyslexia is real, underrecognized, and shows up specifically on standardized tests. Davidson Institute's documentation tells this more directly: "We frequently see children who consistently show good comprehension reading lengthy passages or even long books, yet who significantly under-perform or even fail written tests of reading comprehension because they have difficulty reading short test questions or multiple-choice answers."

If your high-performing teen has a mysteriously stuck ACT score, dyslexia may or may not be part of the problem. Some examples of this psychological profile include: your teen reads novels for pleasure and writes strong essays and pulls A's in honors English but bombs the ACT Reading section. Stealth dyslexia is a real explanation, and the pathway from "let's get this evaluated" to "let's request 50% extended time" is well-trodden.

Suspect stealth dyslexia? Here are some ways to collaboratively investigate with your son/daughter:

• Look for the discrepancy pattern. The tell for stealth dyslexia isn't merely weak reading, it's reading that's weak relative to everything else. A student who discusses a novel's themes fluently but stumbles reading a paragraph aloud. Strong verbal reasoning in conversation, sluggish performance on timed Reading passages. Gets A's in honors English but has a stuck ACT Reading score. The gap itself is the signal that your teen may be struggling with stealth dyslexia.
• Have them read aloud, once. Most stealth-dyslexic students have spent years avoiding this, so it's diagnostic precisely because it's rare for them. Watch for finger-tracking or losing their place, substituting visually similar words (house/horse), skipping small function words (of, the, was), re-reading lines, or reading accurately but very slowly and effortfully. Comprehension after is often fine, which is the indication of dyslexia.
• Time a reading passage. Give the same passage with and without a clock. If untimed comprehension is solid but timed accuracy collapses, that's the decoding-speed-meets-pacing problem rather than a comprehension problem.
• Ask process questions, not ability questions. "Do you re-read sentences a lot?" "Does your eye lose the line?" "Do you read the answer choices more than once before they stick?" "Is reading on a screen worse than paper?" "Do you run out of mental bandwidth on Reading even when the questions aren't hard?" Reading fatigue that compounds across a section is a classic marker of dyslexia.
• Check your family history. Dyslexia is highly heritable, so a parent or sibling who "always hated reading" is a meaningful clue. Late reader as a kid, avoids reading for pleasure despite being bright, spelling that's worse than their vocabulary would predict, prefers audiobooks.
• Look at the section pattern. Math is often a relative strength (low decoding load), Science more accessible than Reading (charts over prose [if your son or daughter is even taking the Science]), Reading probably the lowest score, English might be mixed. That profile shape is suggestive but definitely not conclusive on its own.

Wouldn't my son or daughter KNOW they're dyslexic? Wouldn't I know?

The students who get diagnosed early are usually the ones who struggled visibly in elementary school: couldn't decode, fell behind in reading, got flagged. Stealth dyslexia is the opposite profile. These kids are bright enough to compensate before anyone notices a problem. They memorize sight words, lean on context and vocabulary to guess their way through, infer meaning from a fraction of the text. The compensation works well enough that they read novels, write strong essays, get all A's. Nobody, including the student, has a reason to suspect anything because the output looks fine.

What they experience from the inside isn't "I have a reading disability." It's "reading takes me forever," "I have to read things twice," "I'm just slow on timed tests," "I hate reading on screens." They've felt this their whole life, so it reads as normal to them, the way you don't notice you're nearsighted if you've never seen clearly. They assume everyone re-reads every paragraph. The Davidson Institute language is exactly this: kids with strong comprehension on long passages who underperform on the short, time-pressured reading of test questions, and the gap between the two goes unexplained for years.

And that gap is exactly where the ACT matters, because the test, not the report card, is often the first place stealth dyslexia becomes visible. Which raises the question every parent asks next: if a student is going to test anyway, is the ACT or the SAT the better place to do it?

ACT vs. SAT for dyslexia

The question isn't "ACT or SAT," it's "which format."

The digital SAT uses short discrete passages, which lowers the per-question decoding load, while the ACT uses longer multi-question passages that demand more sustained re-reading. On the surface, that fact seems to favor the SAT for a dyslexic reader. But the SAT forecloses a choice the ACT keeps open: the SAT is digital-only, whereas the ACT can be taken on paper or digitally, and each format carries a different set of supports.

So the real comparison is three-way, ACT-paper, ACT-digital, SAT-digital, and which one fits depends on your specific reader. A student whose struggle is decoding-dominant may want the digital format's bundled audio tools. A student whose struggle is screen fatigue, annotation, and spatial tracking may read measurably better on paper.

The ACT lets you pick the one that matches the profile. That choice is a huge differentiator.

ACT Accommodations for students with dyslexia

Sources: ACT accommodations policy, Acely's 2026 breakdown, ACT's TAA Accommodations chart.

The table makes the format split concrete, so let's take the two formats in turn, starting with the case for paper, which parents underestimate most.

One of the best accommodations for the ACT is the paper test. Screen-based reading fatigue and visual stress affects a meaningful subset of dyslexic readers, particularly those with co-occurring visual stress (sometimes called Meares-Irlen, which is not a subset of dyslexia but a separate, comorbid disability). These students read more slowly and tire faster on a backlit screen than on matte paper. For them, the digital interface's bundled tools don't offset the underlying cost of the medium itself. Paper with a physical colored overlay can outperform a screen for exactly these students.

Second, annotation and spatial memory. On paper a student can underline, bracket, draw arrows, and physically track their place with a finger or straightedge across a fixed page. Many dyslexic readers lean hard on kinesthetic and spatial anchoring: "the answer was top-left of the page on the right." Digital scrolling and on-screen tools approximate this but don't fully replace the fixed-page spatial map, and re-finding a spot in a scrolling passage costs time.

Third, the large-print booklet. The 18-point paper booklet is a genuine accommodation that the digital magnifier doesn't perfectly substitute for: magnifying a screen reflows or clips the layout, whereas the large-print booklet is typeset for it.

Fourth, simple device/tech anxiety. For a student who already spends working memory on decoding, adding "manage the interface" can be a real tax. Some students just read better on paper and shouldn't be talked out of it.

→How ACT accommodations actually work, what most parents don't know

That said, paper isn't the automatic winner, and for a large group of dyslexic students the digital test is the stronger choice. The digital test can be very helpful for students with dyslexia too, especially the bundled digital features. On the old paper ACT test, getting a line reader, text-to-speech, and color contrast required three separate accommodation requests. On the digital ACT, those are interface features available to anyone who needs them. The biggest beneficiary is the decoding-dominant reader, the student whose core bottleneck is getting words off the page rather than fatigue or tracking. For that student, built-in text-to-speech does the single most important job, and it's available without assembling a stack of separate paper accommodations. For dyslexic students, the format choice itself is a strategic move, and the digital test can be friendlier by default.

The documentation pathway

Before any of these accommodations are real, they have to be documented, and the good news is that most families are closer to qualifying than they think. IEP or 504 is enough. Private psychoed eval if not. For the full walkthrough, see how ACT accommodations work.

Without one, ACT wants documentation from a qualified professional showing phonological processing deficit and reading fluency below what would be expected from the student's intelligence. Evaluations run $1,500 to $3,000 and are reusable for college accommodations.

And if cost is the barrier, the evaluation may not have to come out of pocket at all. Your school may be required to provide a free evaluation under IDEA. Follow the accommodations guide for more information.

The prep approach that actually works

Once the accommodations are in place, the prep itself changes. This is different from generic prep:

• Read efficiently, not faster. Skim for structure. Scan for evidence.
• Practice with the accommodation you'll have on test day, not without it. This one matters more than it sounds. Text-to-speech is a skill, not a switch, and a student who first meets the tool on test day will spend working memory fighting the interface instead of reading. You can get ACT practice tests with "alternate format" tests at act.org/alternate-practice. Practice the actual controls (speed, highlighting, continuous read) on easy material first, so test day is about content, not the tool.
• Audio + visual together (text-to-speech + reading along) often beats either alone.
• Strategic skipping. If a short answer choice takes too long to decode, mark and return.
• Build endurance, not speed. Reading fatigue compounds across two hours.

Where dyslexia hits and doesn't, section by section

• English (mixed). Grammar rules, punctuation, and rhetoric are learnable regardless of reading speed. The bottleneck is reading the longer passages around the questions. With shorter enhanced-ACT English passages, this is less punishing than it used to be.
• Math (often a relative strength). Numbers don't have decoding load. The exception is word problems, where text wrapping costs time.
• Reading (the hardest section). Long passages, short answer choices, fast pacing: the trifecta of dyslexia stressors. Extended time and reading-efficiency strategy matter most here.
• Science (more accessible than it looks). Mostly chart and graph interpretation, not heavy prose. Many dyslexic students do better here than on Reading. Important to note that the science section is no longer mandatory.

There's a single insight underneath all four of those, and it's the one that should drive every prep decision you make. The decoding-vs-comprehension dissociation is the prep insight. Research consistently finds that once a dyslexic reader gets through the text, comprehension is often equivalent to non-dyslexic peers. Frontiers in Psychology documents the "dissociation between performance on visual word recognition and/or decoding skills and reading comprehension skills" in college students with dyslexia. The bigger source of points on the ACT for dyslexic students is not "read faster." It's "remove the decoding bottleneck and let the comprehension do its work." That means extended time, audio support, and reading-efficiency strategy, not speed drills (speed drills don't really work anyway until a student can understand the passage, neurotypical or not.)

Dyslexia doesn't cap the outcome: what Yale's long-term data shows

Sally Shaywitz's Connecticut Longitudinal Study, running since 1983, following the same cohort from kindergarten to age 42, establishes that dyslexia exists across the IQ spectrum, persists into adulthood, and does not predict outcomes once supports are in place. Yale students with dyslexia describe it as an asset for their thinking.

Being neurodiverse, of which dyslexia is a subset, is a blessing. It can be a curse without diagnosis, because a person can live their entire life not knowing why they aren't quite normal. But then a diagnosis can help slot everything into place. And when that happens, a person can finally accomplish everything they want.

So if you suspect your son or daughter has dyslexia, or know it but don't have a formal diagnosis, please use the resources on this website. It can only make their life better in the long run.

What to do this month

A few practical steps to start on now. First, request the accommodations evaluation. It gates access to every support above and the clock can run long, so earlier is better. Second, if cost is a worry, look at the scholarship resources on this site before paying out of pocket for an evaluation. Third, get familiar with the enhanced ACT format so the format choice is a deliberate decision rather than a default. And when you're ready to build a dyslexia-specific plan, here's how I work with students.
