Built where reading research and pediatric care meet
Reading Compass deliberately sits between two worlds. Which skills to look at comes from decades of early-literacy research in education. How those skills are read, tracked, and acted on follows a pediatric-style model — the way a doctor uses a growth chart at a well-child visit. And why those skills matter is corroborated by cognitive neuroscience on how the reading brain develops (more on that below). Education research tells us what to measure, brain science tells us why it matters, and the pediatric model keeps it humane and honest. Every threshold, band, and rule was anchored to one of these before it shipped.
A well-child checkup, not a report card.Like a growth chart at the doctor's office, Reading Compass looks at where your child sits in the typical range for their age, and more importantly, which direction they're heading. At three and four, a single snapshot tells you very little; children this age are erratic day to day. The pattern over time tells you almost everything. This mirrors how pediatricians actually work: they track development against age norms across repeated visits, watch the trajectory rather than any single day, and flag a child only when they fall meaningfully outside the typical range — never to label them. We borrow this posture on purpose. That's why you'll never see your child called “failing” or “behind.”
The science of how reading is built.Reading researchers describe early reading as the weaving together of two strands: recognizing words (letters and sounds) and understanding language (listening). Reading Compass is built directly on that model (Scarborough's Reading Rope and the Simple View of Reading), so the skills it tracks are the ones reading scientists actually use.
We measure only what reading science says matters most
Decades of research point to a small set of skills as the strongest early signs a child is on the way to reading. Reading Compass watches four: letters (recognizing and naming them, what researchers call Letter Knowledge), sounds (hearing the individual sounds inside words, or Phonological Awareness), listening (understanding a story read aloud, or Listening Comprehension), and fluency (recognizing letters quickly and smoothly). Each one is a recognized early predictor of later reading, and each is tracked on its own, so a strength shows up clearly even when there's a gap somewhere else.
Letter Knowledge
Recognizing and naming letters
Phonological Awareness
Hearing individual sounds inside words
Listening Comprehension
Understanding a story read aloud
Fluency
Recognizing letters quickly and smoothly
What this looks like in the brain
Brain-imaging research lines up with this. As a child learns to read, the brain builds a dedicated region for recognizing letters and words, and letter recognition is the very first step in how the brain takes in print. That's part of why letters are treated as a real foundation.
What happens next is just as telling: early reading is effortful, leaning on a “sounding-out” pathway to work through each new word; with practice, the brain gradually shifts to a faster pathway that recognizes familiar words automatically. That shift is fluent reading. It happens once a child is actually reading, later than the ages Reading Compass screens, so for us it marks where your child's path is headed — not something we measure today.
Your child, measured two ways, on purpose
Reading Compass reads your child two different ways, because “where are they now” and “where are they heading” are different questions.
Looked at evenly
The overall picture combines the core skills equally. No single skill is allowed to dominate — weighing them evenly is what lets a real gap surface. Your child is then placed in an age-typical band anchored to established literacy assessments.
Weighted by what predicts reading
A forward-looking signal weighs your child's pattern against the skills research ranks as strongest predictors. Listening comprehension carries the most weight; a combined weakness in letters and sounds is the most important early signal to watch.
This is a research-anchored estimate of how your child is tracking toward reading, not a proven prediction. We say “tracking toward,” never “proven to predict.” The value isn't certainty; it's the chance to act early instead of waiting for a problem to surface.
From insight to a daily plan
Knowing where your child stands only helps if you know what to do next. Reading Compass turns the picture into a daily plan aimed at the specific skill where your child has the most to gain, and at the next developmental milestone they haven't reached yet. The plan is built on a simple, consistent daily-practice rhythm — the kind of short, regular practice learning research links to early skill growth.
Activities are playful and hands-on (spotting letters in everyday print, tracing and saying them, one skill at a time) because that's how children this age actually learn best. And the plan adapts: as your child improves, it reshapes itself around what comes next.
A map of how reading is built
Your child's progress is shown against eleven developmental milestones — the real, research-described steps children move through on the way to reading, with the sources shown right on the screen. These milestones predict reading readiness; they don't pretend a preschooler is already a reader. True decoding and reading connected text come later, and our language is careful never to overstate where your child is.
The picture sharpens every time you use it
A single session is a snapshot. The trajectory across sessions is the real story — the same principle as a pediatric growth chart. So Reading Compass saves every session, measures growth against what's expected for your child's age, and suggests when to check in again. The check-in rhythm follows the same cadence schools use to monitor a child's progress: regular, every few weeks. You can even listen back to your child's actual recorded answers, which is often the most meaningful evidence of all.
What Reading Compass is, and isn't (yet)
We think you can only trust the rest of this page if we're straight about the limits.
- It's a research-grounded screen, not a diagnosis.The forward-looking signal is a careful estimate built from published benchmarks and well-established screening practice, not yet confirmed by a long-term study following children from preschool into reading. That study is our roadmap. And while we borrow the pediatric model's posture and built the tool under a specialist review, Reading Compass is not a medical device and does not diagnose.
- Its norms are provisional by design.They're built from research modeling for now, and the system is built to swap in real-world norms once we've gathered enough data — without losing your child's history.
- We use “age-typical,” not our own percentiles, for the same reason.
- The research base is strongest for English-speaking children(largely US, UK, and Australia) and isn't validated for other languages.
- A couple of predictors aren't measured yet — a small, known, deliberate gap, not a hidden one.
