Results included in these documents were generated from tests administered statewide during a school year. The local schools or school systems scanned the students' answer sheets with proprietary software developed by the North Carolina Department of Public Instruction. The data were sent to the North Carolina Department of Public Instruction where they were concatenated. The data analyses and reporting are limited to traditional public schools and charter schools. In addition, confidentiality ethics do not permit references to subgroups with less than five students.
