How the i-Ready reports it

i-Ready Diagnostic is a vendor-developed adaptive assessment, not a state test, but Curriculum Associates reports results and alignment against state standards such as Virginia SOL. The math coverage is organized by grade-level content domains that closely track Common Core-style strands rather than a single fixed claim structure.

Blueprint & weighting

No official per-domain blueprint or item-weight percentages were found on the official product page; i-Ready publishes adaptive diagnostic results and domain placements rather than a public fixed-item weight table.
