- Latest Iowa Statewide Assessment of Student Progress show English language art proficiency is improving.
- Students with disabilities and those learning English continue to lag behind peers.
Iowa students have begun to show improvement in English language arts, according to newly released state testing results.
Iowa’s English language arts proficiency rates ranged from 68% to 80% on the 2025 Iowa Statewide Assessment of Student Progress, according to a state Department of Education news release.
“(S)tudents who were in third grade during the 2023-24 school year showed outstanding gains as fourth graders in 2024-25, with ELA proficiency increasing 11 percentage points,” the release said. “Compared to last year, ELA proficiency rates increased or were maintained in grades 3-5 and 8-10, with grades 3 and 8 showing the most significant increases of 4 and 3 percentage points, respectively.”
Iowa Statewide Assessment of Student Progress (ISASP) is a yearly assessment tracking proficiency in math, science and English language arts for students in third through eighth grades. Freshmen, sophomores and juniors also take some of the assessments.
Iowa officials are crediting a 2024 law as part of the reason students’ ELA scores are holding steady or improving. That year, Gov. Kim Reynolds signed House File 2618 into law, which focused on improving Iowa’s literacy rates.
Reynolds praised the work being done across the state to boost literacy, including teachers taking part in professional development.
“Iowa made literacy a priority in every classroom and for every student over the past year by implementing proven, evidence-based approaches that we know work,” Reynolds said in the news release. “By empowering Iowa teachers with critical training in the Science of Reading and through strong collaboration with students, families and school partners, ELA proficiency for last year’s third graders jumped an impressive 11 percentage points just one year later.”
How Iowa students scored in math
Students’ ISASP mathematics proficiency scores ranged between 64% and 76%, according to the news release.
During Iowa’s 2025 legislative session, lawmakers passed House File 784, also known as the Math Counts Act, which requires students in kindergarten through sixth grade to be tested three times a year to check math proficiency. If a student is found to be struggling, school officials are required to create a personalized support plan.
“Math proficiency in high school grades is much lower than that of earlier grade levels, with differences ranging between 4 to 12 percentage points lower,” the release said. “Students in ninth grade experienced the largest long-term decrease in math proficiency, down 5 percentage points from 2019. Compared to last year, math proficiency rates do not show change beyond 1-2 percentage points, reinforcing the need for the Math Counts Act passed in 2025.”
“The data show Iowa’s investment in evidence-based literacy instruction is working, and, last winter, we set out to mirror these transformational structures in math through the historic Math Counts Act,” Iowa Department of Education Director McKenzie Snow said in the release.
Science proficiency on the rise
Students’ science proficiency is also on the upswing. Those rates were between 64% and 70%.
“This spring, science proficiency rates show gains across all tested grades, exceeding pre-pandemic performance with a 12-percentage point increase in both 5th and 8th grade since 2019,” the release said. “In just one year, science proficiency increased by 4 percentage points in fifth grade, 5 percentage points in eighth grade, and 7 percentage points in 10th grade.”
While the data shows improvements in ELA, math and science scores, student subgroups including those with disabilities and English learners continue to lag behind their peers.
The “average differences across grade levels in ELA proficiency of 45 and 53 percentage points, respectively,” according to the state’s news release. “The average proficiency rate gaps in mathematics for students with disabilities and students who are English learners was slightly lower at 41 and 45 percentage points, respectively.”
