The Northwest Evaluation Association (NWEA)[1][2] is a division of Houghton Mifflin Harcourt (acquired by HMH in 2023) that creates academic assessments for students pre-K-12.

[4] Its primary assessment product is the MAP Suite, a collection of formative and interim assessments that help teachers identify unique student learning needs, track skill mastery, and measure academic growth over time.

MAP assessments are graded using the RIT scale, measuring between 140 to a maximum of 300.

NWEA Secure Testing has a major advantage over the website, as it restricts test-takers from external digital information on their device, locking them on the assessment and nothing else.

In January 2023, it was announced that Houghton Mifflin Harcourt had acquired NWEA and would operate as a division of HMH.
