The method that measures your child's development.
Measure across 6 domains → follow a 90-day plan → re-measure every quarter. Clarity instead of guessing, for the whole window.
A real assessment, in 5 minutes
Simple everyday questions become your child's development map across 6 domains — where they're strong, and where a little attention will matter most.
90 days on what matters
The plan targets the focus areas the map revealed — a few minutes of play a day. Early, targeted, measured practice is what compounds in this window.
See the lines move
Every 90 days, a fresh assessment overlays the last one. Progress isn't a feeling — it's measured. Then the loop starts again, from where your child actually is.
↻ Measure → Plan → Re-measure — quarter after quarter.
Grounded in real frameworks
The assessment is grounded in established references — translated into a plan a parent can actually run.
Denver II
The developmental screening reference used worldwide to identify where a child stands across domains.
BNCC
Brazil's national early-childhood learning base — what children should be exploring and learning, year by year.
SBP milestones
The Brazilian Society of Pediatrics' developmental milestones — the same references your pediatrician uses.
Why trust it
For nine years I ran a school — nine years spent inside the one window of childhood that builds the brain and never repeats. And every year I saw the same quiet heartbreak: parents who loved their kids fiercely, watching the most important years slip away — not because they didn't care, but because no one could tell them where their child actually was, or what to do next. Everyone was guessing. But guessing, in the years that decide everything, is the most expensive mistake a parent can make. Therefore I built the way to stop guessing: an assessment that shows any parent or teacher exactly where a child stands — and exactly what to do to help them reach their full potential. That's the firstk Method.
This wasn't built in a lab. It was built in a non-profit school that has cared for underprivileged children since 1973 — kids who can't afford to waste the window. And for decades, even there, teachers assessed by instinct. But the moment they started measuring with this method, everything changed: they could finally see each child clearly, target exactly what each one needed, and watch the progress stack up, quarter after quarter — and teachers and parents alike have seen it. Therefore what began as a tool for one school became the firstk Method — the same measurement, the same 90-day clarity, now for your child.
What you get, every quarter
The map
Your child's development, measured across 6 domains — honest and specific.
The 90-day plan
A few minutes of play a day, aimed exactly at the focus areas.
The coach
Support while you run the plan — questions answered, whenever you need.
The re-measurement
Every 90 days — so you see measured progress, not a guess.
The firstk assessment is a tracking and stimulation tool — it does not replace medical evaluation. If concerned, consult a pediatrician.
