Iowa schools saw declining math and reading scores on state accountability exams last spring, resulting in fewer K-12 schools receiving high rankings in a state report card this year.

The percentage of schools that received an exceptional, high-performing or commendable ranking fell from 43 percent in 2016 to 37 percent in 2017, according to state data released Wednesday.

Families can look up their individual school's performance on the Iowa School Report Card website. Des Moines-area school rankings are listed below.

Nearly all grade levels showed stagnant or falling scores in math or reading, according to a Register analysis of test results.

Some had sharper declines than others. For example, third grade achievement fell in both reading and math when comparing state test data for the 2015-16 and 2016-17 school years.

Last school year, 75.4 percent of third graders were reading on grade level, down from 76.9 percent the previous school year.

In addition, 77.9 percent were performing at grade level in math, down from 79.8 percent previously.

"These results reinforce the need to continue moving forward with the bold education initiatives Iowa has put in place to strengthen instruction and prepare students for success in high school and beyond,” said Ryan Wise, director of the education department, in a news release.

In addition to academic achievement and growth, the ratings include factors such as how well the school has done in narrowing the achievement gap among at-risk students and preparing students for college or careers.

Student attendance and staff retention are also factored into the rankings.

Schools can earn one of six ratings: Exceptional, High-Performing, Commendable, Acceptable, Needs Improvement, and Priority.
