Iowa Assessment Results

Recently we received our Iowa Assessment Results from our testing during November of 2014.  We reviewed the information with students and then sent the results home with students.  As a school system we are reviewing our Iowa Assessment  data and looking at three-year trends in our data.  This work ties directly into defining our Priority Standards and defining Learning Targets (I Can Statements) to those standards.  We are also triangulating our Iowa Assessment data to our classroom assessments and observations to make possible adjustments to our curriculum.  

As you may be aware, in 2011-2012, the new Iowa Assessments test replaced the Iowa Tests of Basic Skills (ITBS) and Iowa Tests of Educational Development (ITED).   The Iowa Assessments offer new and different data, and because of this, you may need information to assist you in interpreting your student’s scores.  The Iowa Assessments may provide valuable information about the yearly academic growth of students. It may also provide strong indicators of college readiness.  Student academic growth is monitored based on something called a “standard score”.   Interpreting Iowa Assessment Results

National Standard Score (NSS)

The National Standard Score, or NSS, describes performance on a continuum from kindergarten through high school. The continuum is based on scores from testing thousands of students and determining where students at certain grade levels fall within a range.

The achievement continuum connected with the Iowa Assessments is divided into three categories: Non Proficient, Proficient, and Advanced. Using these scores allows teachers, parents and students to track not only proficiency at a test time, but year-to-year growth.   Standard Score Ranges for Achievement Levels for Reading, Math and Science

National Percentile Ranking (NPR)

The Iowa Assessments also include a National Percentile Ranking (NPR). This compares a student’s score with others in the nation in the same grade who took the test at the same time of year. The NPR is based on a scale of 1 to 99, so if a third grade student receives an 75 that means the student did as well or better than 75 percent of other third graders in the nation taking the test at the same time.

In past years this NPR has been the more important score on the ITBS or ITED. With the switch to the new Iowa Assessments the NSS will be the more important indicator of student achievement, as it will be easier to track one student’s growth year to year, instead of compared to other students.   Interpreting National Performance

Here's a snapshot of our Iowa Assessment Results from 2000-2014 based on percent proficient in grades 3-11.
