GREAT is a gang and violence prevention program built around school-based, law enforcement officer-instructed classroom curricula. The program is intended as an immunization against delinquency, youth violence, and gang membership for children in the years immediately before the prime ages for introduction into gangs and delinquent behavior. GREAT lessons focus on providing life skills to students to help them avoid using delinquent behavior and violence to solve problems. The GREAT program offers a continuum of components for students and their families.
