Memo Text

The Assessment Correction Engine (ACE) interface will be available to all districts from August 8 through August 22 at the ADE Data Center. Districts MUST use ACE to certify assessment data and MAY submit documentation to remove eligible students from their denominator for expected to test. All data must be certified by the district superintendent no later than 5:00 p.m., August 22, 2022.


The School Performance Unit will provide two “ACE”-ing Test Corrections sessions for district and school-level staff on August 1st at 1:00 PM and August 3rd at 9:00 AM. Register now using the links provided.


Superintendents must log in to CERTIFY their district’s data. However, the superintendent may designate someone to make corrections on their behalf. Districts are strongly encouraged to review their participation rate data (percent tested) and enter any needed Reason Not Tested (RNT) codes and documentation as early as possible. Only data for the 2021-2022 school year can be changed.

The resulting post-appeal accountability information will become part of the data incorporated in the accountability plan required by the Every Student Succeeds Act (ESSA). DESE will use the data in the ESSA School Index, School Performance Report Card, and Rewards/Recognition calculations. Please use this time to make sure the data are accurate.


Contact the School Performance Unit at or (501) 682-7339 for more information regarding assessment corrections.



The 2023 Business Rules for Calculating ESSA School Index Scores have been finalized following a draft release and a peer review period. An additional section of information about the Alternate Pathway to Graduation was added, which applies beginning with the graduating class of 2023. Other stakeholder feedback was considered and minor edits were made accordingly. The Business Rules should be used to inform districts how ESSA School Index Scores are calculated for All Students and subgroups of students.


For more information on changes to the 2023 ESSA Business Rules, see COM-23-001.

Informational documents explaining the ESSA School Index, indicators, and components are posted on the Arkansas Department of Education website at
