Keep in mind this chart is for the beginning of the year grade levels (so Fall testing).

It looks to me that a Math RIT of 249 in Math would put her as a High Achiever for beginning of the year grade 6 and a median achiever for beginning of the year grade 10.

A General Science RIT of 232 would put her very close to being a High Achiever for Grade 9 for beginning of the school year and is off the chart for median achievement.

Student Growth presents the growth in RIT your child has made from the previous fall to the spring of the year in which growth is reported.

Typical Growth is the average growth of students in the most recent NWEA RIT Scale Norms study, who were in the same grade and began the growth comparison period at a similar achievement level.
