School accreditation is the accountability system for Virginia’s public schools. Performance on various School Quality Indicators is measured for “all students” at a school and its various demographic groups. For all “students” at a school, the indicators are Standards of Learning (SOL) test results in English, math and science as well as chronic absenteeism. High schools have two more indicators: graduation completion index and dropout rate. For demographic groups (Asian, Black, Hispanic, white, economically disadvantaged and students with disabilities), the indicators are only English and math SOL test results.
