Reading doesn’t just happen

The system says “Wait and See.”
Science says Act Now.

We are not born to read

Reading is not built into our DNA; it is a complex code that must neruologically wired with no gaps.

Strong early foundations are critical

Science tells us that the window to wire the reading brain for mastery is SK to 3. Beyond that, kids hit the grade 4 wall.

The statistic 60% shattering, highlighting the systemic failure of standard reading instruction.

Don’t “Wait and See”

Up to 60% of 4th graders are not proficient readers. The system leaves too many gaps for too many kids, even the smartest ones.

The world’s most rigorous professional teaching tool for reading, now available to families with expert fidelity from Radical Reading.

Lexia® Core5®:
The world’s most powerful reading tool, now in your livingroom

Originally developed decades ago through Johns Hopkins and Boston Children's Hospital, what is now Lexia Core5 has been at the forefront of the science of reading ever since.

Lexia adapts to each student with a personalized learning path to build one small skill after another, using extensive built-in supports, plus flags for 1:1 precision lessons when needed.

So every child builds strong reading foundations, with no unfinished learning and no gaps to widen. It’s also an effective early screener for dyslexia and other LDs, so you know your child won’t fall through the cracks. There is no more powerful or proven tool than Lexia Core5.

Usually kept behind school district walls, Radical Reading brings this powerful tool to your living room, under our expert guidance.

If Lexia is the rocketship, Radical is your pilot

Lexia is not a reading app. It’s a professional clinical tool designed to be guided by teachers and supervised by experts.

While your child is building skills, Lexia is gathering data, and we’re watching their momentum, ready to step in with expert guidance, motivation or targeted lessons to keep the momentum. We make sure the rocket reaches it’s destination.

How it works

Lexia Core5 helped 3.7 million kids last year

Developed and refined over decades, extensively researched and proven. Here's what makes it so powerful for every young reader.

Personalized adaptive learning

Lexia responds to your child in real-time. If they master a concept, it accelerates them instantly. If they "wobble," it branches into an instruction sub-path. No time is wasted on what they know; no gap is left where they struggle.

Comprehensive skill development

Systematically builds skills across six pillars of reading: Phonological Awareness, Phonics, Structural Analysis, Fluency, Vocabulary, Comprehension. Every small skill is fully developed before moving on. No gaps equals mastery.

Continuous assessment and screening

Lexia's Assessment Without Testing® tracks progress in real time using detailed and timely data so no child falls behind. It also acts as a predictive screener, flagging potential issues years before the school system would.

Expert oversight

Our Education Director monitors every child, every week. We don't wait for report cards; we see the "wobbles" the moment they happen and pivot instruction instantly.

Precision intervention

When the data flags an issue, we provide targeted, 1:1 precision lessons. We provide the human expertise to "weld" the weaK connection the software identified.

Radical accountability

School report cards are vague. Our data is granular. You’ll get a monthly report showing exactly how your child is progressing.

We deliver fidelity. Fidelity delivers results

In education, fidelity is the ability to deliver a program the way it was intended. I founded Radical Reading to give parents a way to bypass the uneven results of the school system. We took the leading clinical-grade tool and designed a home-based system for fidelity and success. We don't hope for progress; we engineer it. That’s Radical.

Radical for a reason

Lark helped define the Right to Read for all Ontario.

Now she delivers it for you.

Lark Barker is our Director of Education. She has been a driving force behind Ontario’s landmark Right to Read movement, dedicating years to exposing the gaps in public education and helping rewrite the curriculum to fix them.

But she’s learned a hard reality:
System change takes years. Childhood happens now.

Lark built Radical Reading to bridge this gap, to provide the immediate, individualized clinical precision that school systems still struggle to deliver at scale.

About Us
Infographic showing the compound interest of early reading success versus the silent squandering of hitting the 4th grade wall.

It starts with words, but it ends with the world.

Strong early reading lifts the trajectory of a life. But too many kids never build the foundation to reach their potential. As an educator, advocate and parent, I knew I needed to do something about the silent squandering.
