Additional Targeted Support and Improvement

ATSI refers to a designation given to schools under Nevada's federally-approved Every  Student Succeeds Act (ESSA) Plan. ATSI schools have very low-performing student  subgroups that, if those subgroups' performance were considered on their own, would lead  to a Comprehensive Support and Improvement (CSI) designation.  In short, these are schools identified as needing improvement due to the consistently low  performance of specific student groups.
