The model was developed by a task force formed to describe State data collection systems and recommend to the States and to the National Center for Education Statistics a model set of definitions and a data system that could be implemented in a State or adapted for use in a school district. The report recommends two types of records for the data system: an incident record and a participant record. It also recommends that data be collected based on school year; that specific incidents be covered; and that information cover all incidents on school grounds, school transportation, and off-campus school sponsored events when a student is involved. Further recommendations are to report elements such as the presence of alcohol, drugs, or weapons; whether the incident is gang-related or motivated by hate; and whether the incident is reported to the police; and always to report the most serious of actions in an incident with several offenses.
