Last academic year, law-enforcement personnel on school campuses committed 180 assaults on students, a 21% increase from the prior year and the worst year in at least a decade, according to a new study. Texas had the nation's second-highest number of assaults last year at 39, while Florida led the nation at 53, according to the analysis, which was released Thursday by watchdog groups the Advancement Project and Alliance for Educational Justice. The report looks at assaults by police and security guards directed at students on K - 12 campuses from the 2013-2014 academic year through last academic year.
