Data starting in 2019 are based on results from the Iowa State Assessment of Student Progress (ISASP), which was first given in spring of the 2018-19 school year. Data before 2019 are based on results from the Iowa Assessments, which were given for the last time during spring of the 2017-18 school year. Use caution comparing achievement levels across those time periods. 


Data also include results for students assessed using the Dynamic Learning Maps alternate assessment. Data exclude English learners who were in their first or second year enrolled in the U.S.
