Of students who took the corresponding section of the ACT approximately: 56% met the Iowa Assessment Reading benchmark; 74% met the Iowa Assessments Written Expression benchmark; 50% met Iowa Assessments Mathematics benchmark; and 46% met Iowa Assessments Science benchmark. Of students who took all four corresponding sections of the ACT, 34% met all four Iowa Assessment readiness benchmarks. **Not all students in the state of Iowa complete the Written Expression test.
Part 3: College Readiness Benchmarks for all Iowa
Students Figure 1 shows the percentage of examinees that met or exceeded the college readiness benchmark score on each of the four Iowa Assessment tests. Figures 2-9 show the percentage of examinees separated by gender, FRL, and race that met or exceeded the college readiness benchmark score on each of the four Iowa Assessment tests. Figures 10-11 show the percentage of examinees, separated by the same groupings, that met or exceeded the college readiness benchmark scores on all four of the Iowa Assessment tests. For the graphs that show performance by race, there are individuals of other ethnicities, such as those of Native American background, that also took the content area tests, but the size of the samples were too small to adequately represent average performance of these ethnic groups.
