Gang Resistance Education & Training (GREAT)
The Gang Resistance Education And Training (G.R.E.A.T.) Program was developed in 1991 by a combined effort of the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives and the Phoenix Police Department. G.R.E.A.T. 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.
