NWEA

A nonprofit assessment vendor (acquired by HMH in 2023) that develops MAP Growth, the most widely used K–12 interim growth assessment in the U.S. Distinct from state-accountability vendors like Smarter Balanced in that MAP Growth is a growth assessment — administered multiple times per year, reported on a continuous RIT scale with no proficiency bands and no cut scores. Centers its parent communication on percentile rank and growth trajectory rather than on whether a child has met a fixed standard.

What parents see

The MAP Growth family report shows a RIT scale score, an achievement percentile vs. a national norm group, a national-average reference line, and (after multiple administrations) a growth percentile. NWEA's stated parent-facing question is "Is my child learning and growing at a healthy rate?" rather than "Did my child pass?" See family materials source.

How NWEA explains scores to families

NWEA's main analogy for RIT is "an equal-interval scale, like feet and inches on a ruler." Its public Goal Explorer tool lets a parent input a fall RIT and see a range of fall-to-spring growth targets relative to the norm group. Its 2024 explainer of "six commonly used MAP Growth terms" tells parents that if they encounter unfamiliar terms, they should ask the teacher.

Notable absence

NWEA does not map RIT scores to specific real-world capabilities, career-readiness milestones, or concrete skill descriptions. Score interpretation is entirely internal to the testing system (other scores, norms, growth percentiles).

Follow-ups

• Whether NWEA partners with National PTA or any parent-advocacy organization on family communication, the way Smarter Balanced has.
• Districts using MAP Growth alongside a Portrait of a Graduate framework — does anyone bridge the two systems for parents?
• HMH's product strategy post-acquisition: any moves to integrate MAP Growth scoring with HMH curriculum or competency materials.
