CMAS Math, ELA, CSLA, and Science; CoAlt Science SBD


The purpose of the CMAS/CoAlt: Science, English Language Arts and Mathematics, and CSLA Student Biographical Data (SBD) review is to allow districts the opportunity to verify the accuracy of the demographic data submitted for each student participating in each of these assessments. The review process takes place after the test window has closed and before all assessments have been scored and final results made available.

State and federal accountability reporting including school and district performance framework ratings (e.g., Performance Plan, Improvement Plan, Priority Improvement Plan, Turnaround Plan) and federal identification (i.e., Comprehensive Support, Targeted Support, or Additional Targeted Support) all rely on accurate demographic and test score data. Districts are not required to participate in the SBD review process. Note that the request to reconsider process cannot be used to address district reporting errors that should have been corrected during SBD. To learn more about uses in accountability, view the SBD and Accountability fact sheet.


  • The CMAS SBD review window for the 2023-2024 school year is Thursday, May 16, 2024 through Wednesday, May 29, 2024.
