Family & student support
Beyond test scores: official, public measures of student support and community context that families ask about. District- and county-level only; never a rating of an individual school, student, or home.

Bullying counts are incidents a district formally reported under federal civil-rights categories, a widely underreported measure. A low number (including zero) often reflects reporting practices more than the absence of bullying.
These figures describe districts and counties, not individual schools, students, or homes. They are official public data and may be self-reported, lag by a year or more, or be underreported. They are context for families, not a safety rating.
