Iowa Test of Basic Skills Composite Scores

April 2015

ITBS 2015The Composite Score is a percentile – not a percent. A percentile of 80 means your child scored better than 80% of the students who took the same test.
Illustration: Imagine there are 100 3rd graders in a room. Based on the CLS percentile of 80, your child would score better than 80 of the 100 students in that room.
1-3: Below Average
4-6: Average
7-9: Above Average

CLS is proud of our students’ accomplishments on the Iowa Test of Basic Skills. We continue to challenge our students, knowing each year they can individually excel. By sharing these test scores, we are illustrating the positive tangible results of sending your child to CLS, where we value academic excellence and individual achievement.
