Alcohol abuse affects the entire family, yet only recently has attention focused on the needs of children with parents or guardians who abuse alcohol and/or other drugs. Professional school counselors (PSCs) must be prepared to identify and address the needs of these students. Parental alcohol abuse presents serious academic, emotional, physical, and social problems to families, schools, and society at large. Alcohol-abusing parents generally are ineffective in meeting their children's educational, developmental, social, and emotional needs (Robinson & Rhoden, 1998). Therefore, early prevention and intervention efforts are essential in these students' lives. Children of alcoholics (COAs) need the support of professional school counselors (PSCs). These students' family dysfunctionality places them at high risk for adverse academic, physiological, emotional, and social consequences. This article (a) introduces alcohol abuse as a family illness, (b) describes the possible effects of family alcohol abuse on children, (c) identifies potential indicators of COAs, and (d) offers suggestions that PSCs may implement to support students and their families. Currently, many COAs remain unidentified within schools; therefore, these students may not be receiving the counseling services they deserve and require.
