A bolded value is the more favorable of the two where the metric has a clear direction. Metrics like population and density have no inherent better or worse and are shown unweighted.
Georgia and South Carolina do not give the same test. Each state writes its own assessment and sets its own passing score, so the two proficiency rows above are not directly comparable — the difference between them partly measures which standard is harder. Students per teacher and the school count are unaffected, and each profile ranks its own proficiency within its own state.
