A student's RIT score increased over time, but their percentile rank decreased. How is this possible?

It is possible for a student to show RIT score growth while their percentile decreases. This indicates that the student did not grow as much as the typical student in their grade, so their percentile rank as compared to other students is lower.

This discussion in NWEA's community site, NWEA Connection, gives an example of 3 students who ended the year at the same percentile, and one of the student's percentile rank had decreased from the beginning of the year, even though the student had positive RIT growth.
