The Assessment Correction Engine (ACE) gives Arkansas LEAs and their Superintendents the ability to review, attempt corrections, and certify their Elementary and Secondary Education Act (ESEA) assessment data.  

The School Performance Unit processes corrections for the following assessments annually:

Statewide Summative Assessment:
ELA - Reading & Writing (Grades 3-10), Math, and Science (Grades 3‐8), Algebra (Grade 9), Geometry (Grade 10), and Biology (Grade 10)

Statewide Alternate Assessment: 
ELA (Reading & Writing), Math, and Science (Grades 3‐10) 

All eligible students are expected to participate in the annual statewide assessment including full-academic year and highly-mobile students.

Students who were expected to test in a particular subject but failed to do so may have Reason Not Tested (RNT) codes assigned indicating why the student did not test.  Some RNT codes will negate the student's test expectation, thus improving the participation rate or percent tested for the associated subject in the school.

For more information on reasons why a student may be excluded from a school’s expectation to test and the required documentation needed to remove that student from the school’s enrollment, refer to the 2024-2025 ACE Guidebook.
