At the beginning of the school year, skeptical parents worried that their own math deficiencies might foreshadow similar difficulties for their children just entering sixth grade. Those fears turned out to be wildly unfounded. By the end of the year, their sixth graders had collectively mastered more than 2,000 grade-level or higher math objectives. Overall, the class of 20 averaged a five-grade-level jump in skillsets, with six students finishing in the 99th percentile and more than half ranking in the 90th percentile or higher on Renaissance Star Math® assessments.
