Evidence & research

The science we build from. The methodology we ship with.

Storytime is grounded in the converging cognitive-science consensus on how children learn to read — not in a single proprietary methodology. Here's the research that shapes our product decisions and the methodology behind our assessment instruments.

Five-pillar foundation.

Storytime instruction targets phonemic awareness, phonics, fluency, vocabulary, and comprehension — the five pillars identified by the National Reading Panel (2000) and replicated in 25+ years of cognitive science.

ESSA Tier 4 evidence rationale, documented.

Storytime maintains a published logic model + research base meeting the ESSA Tier 4 ("Demonstrates a Rationale") standard. Tier 2 / Tier 3 evidence comes from pilot evaluations — partnerships welcome.

Transparent methodology.

Our placement assessment uses 12 universal SoR checkpoints validated against established screeners. ORF scoring uses Hasbrouck & Tindal benchmarks. Skill Tree mastery levels map to grade-band norms.
