There's no single definitive answer to the question of "most dangerous high school in America." There's no central, nationally standardized database tracking all incidents of violence and crime in every high school across the country. Different schools use different reporting methods, and data collection varies significantly by state and locality. Rankings you might find online are often based on limited or potentially biased data and shouldn't be taken as completely accurate or representative.
Focusing on crime statistics alone is also problematic, as it doesn't capture the full picture of a school's safety. Factors like school climate, student support services, and disciplinary practices all heavily influence the overall safety and well-being of students, regardless of crime statistics.
