Schools are the principal government-sponsored institution involved with the socialization of children, and the school can also influence families through involving parents in the school-based socialization of their children. Carefully designed and implemented educational interventions in the preschool, elementary, and secondary-school years show beneficial outcomes for a time. Structured methods have potential for upgrading schools through better instruction, classroom management, and discipline practices. Intensive, high-quality educational and behavioral programs -- applied early and continuing throughout the school careers of youths at high-risk of educational failure and other problem behaviors -- would likely produce substantial reductions in school misconduct and delinquency and substantial improvements in learning and school completion. Some common practices with problem students, such as special education assignments, pull-out programs, and the grouping of troublesome students together may do more harm than good. Placement outside mainstream classrooms should be avoided when possible. 111 references.
