What we believe
Prevention over Intervention. No child left behind, or held back.
Radical's Director of Education, Lark Barker, helped shape Ontario's Right to Read movement — a decade spent changing how schools teach reading. Radical is how she completes that work: one child at a time, with Lexia in your living room.

What we want for every child
For Now
And for a lifetime
A child who reads with ease reads more. And every book lifts the next. Confidence grows, subjects open up, and the slope of their whole education tilts upward. Reading that never quite clicks quietly caps what a child will try. Early mastery raises the ceiling on everything that comes after.
