Background: New Jersey (NJ) Safe Schools Program, primarily funded by the NJ Department of Education, has aims concerning safety and health including helping to alleviate harassment, intimidation, and bullying (HIB) in secondary school because HIB can affect learning. We evaluated officially reported adolescent HIB total incidents and estimated rates in NJ public city and county school districts for the 2011-2016 school years. Methods: A cross-sectional observational study using population-based state-reported public data. We calculated point prevalence and incidence rates for K-12 students in 22 public city school districts, students in 21 career-technical-vocational education (CTE) school districts, and 8 special services school districts during 2011-2016. Results: HIB is prevalent in NJ school classrooms. HIB comprised [greater than or equal to] 75% of total officially reported in-school violence-related incidents in a given school year. Rates per 100 enrollees of total officially reported incidents for the 5-year period of 2011-2016 was highest in special services school districts (5.00; 95% confidence interval [CI]: 4.67, 5.34) followed by CTE districts (1.94; 95% CI: 1.86, 2.01), and lowest in city districts (1.46; 95% CI: 1.44, 1.48). The special services school district also had the highest rates per year and the 5-year period. Conclusions: Data analyses suggested ideas for further research and improvements for school HIB incident reports. Policies and programs could remedy issues observed in state secondary school classrooms. Best practices within districts and schools can help protect students from HIB and promote safety, health, learning, and maturation.
