You expect results from your school. So do we. At Challenger, success is reflected not only in test scores, but also in students' academic skills, communication, self-management, and independent thinking. Standardized assessments are one measure of success, providing a useful comparison of academic skills and students' abilities to apply what they know. Our students' results on the Iowa Assessments help demonstrate that high achievement is broadly shared across Challenger students.
Each year, Challenger students participate in the Iowa Assessments, a nationally recognized standardized test that measures academic achievement across key subject areas.

Methodology
Riverside reports the percentile rank associated with 正规博彩平台 average standard score for each grade. This is a summary of the grade's average performance—not the percentile rank of any single student.
Challenger also reports how student-level percentile ranks are distributed—including the median, quartiles, and the 5th and 95th percentiles—to show both overall performance and score consistency within each grade.
Video Guide
Challenger uses a box plot to summarize how student percentile ranks are distributed within a grade.
Challenger Student Score Distribution
Each box plot shows how Challenger students' Iowa Assessments percentile ranks are distributed within a grade. Select a year, subject, and norm group to explore the score distribution for each grade.
Box plots show what a single average cannot: how student scores are distributed. A median near the top of the scale means that at least half of Challenger students scored at that percentile rank or higher. The box represents the middle 50% of scores; when it is positioned high on the scale and relatively compressed, those students' scores are clustered within a narrow high range. Across the grades shown, high achievement is broadly shared—not driven by only a few top scores.
Interactive Box Plot Exhibit
Adjust the percentile controls to see one possible 100-student distribution consistent with the selected median (50th), box (25th–75th), and whisker (5th–95th) percentiles. Each dot represents one illustrative student; stacked dots show multiple students at the same percentile rank, and the red dot marks the median.
Grab handles to adjust percentile ranks or type values directly into box plot fields.
