Iowa Test of Basic Skills – Spring 2010

Percentile Scores: National School Norms

Notes:

• 4^th grade is the first time that students at HVCS take the Iowa Test of Basic Skills.
• Percentile scores range from 0 to 99. The 50^th percentile is average.
• The Composite score is the average of the other scores. This year all the grade level composite scores are in the 87th percentile or higher and in specific subject sections, students scored in the 77^th percentile or higher.
• In particular we are interested in the scores of the 8^th grade class; All of the subject area scores are 83rd percentile or higher, an indicator of preparedness for high school academics. Also, the composite scores of our 7^th and 8^th grade classes are in the 90^th percentile!

Tracking individual classes:

We tracked the composite scores of four different classes over the past three years.

Testing analysts caution against drawing too many conclusions from:

• small sample sizes (like ours), and;
• composition of groups changing from one year to the next (in our case, adds and drops to particular grades.)

Nonetheless, we felt it helpful to look at the progress of students by class.
