Bullying can create a climate of fear and discomfort in schools and communities. This study examined the longitudinal associations between children's bullying, special education placements in elementary school, and serious delinquent behavior during secondary school. Using data from the youngest sample of the Pittsburgh Youth Study, the authors examined these associations while controlling for prior poor academic achievement and aggression. They found that contrary to prior research, neither special education placements nor poor academic achievement predicted bullying or serious delinquency. They found substantial continuity between early aggression and special education placements, bullying, and serious delinquency. They discuss the implications of our finding for future research and policy development. (Contains 4 tables.)
