Educating parents, school staff and students about street gangs is crucial. Street gangs have been identified in the northwest suburbs. School administrators and the middle and high school resource officers educate staff, students and parents of gang trends, colors, signs and activity. Gang behavior in school can be followed by discipline depending on the circumstances. You can report possible gang activity to the District Safety Department at (847) 888-5000 ext. 4263 or on the anonymous tip line of your school.
