The NWEA Norms Study includes both status norms and growth norms. What is the difference between the two?


Status norms

Also known as percentile rankings, status norms are a one-time snapshot of student performance. A student's RIT score will have an associated percentile ranking, showing how well they scored compared to students in the same grade and subject. Similarly, the school norms provide percentile rankings for groups of students. For example, your school's 5th grade average RIT is compared against the average RIT for other 5th grade classes in the same subject.

Status norms can also refer to the overall mean RIT for a particular grade and subject.

Growth norms

Growth norms measure student performance over multiple time points. We measure the average RIT score change by grade for a given period of time, for example, the average RIT score change from fall testing to spring testing. An individual student's growth projection is the average RIT score change for students in the same grade, subject, and starting RIT.
