A study is described which examined the relationships between law-related knowledge, attitudes, and demographic characteristics of high school students. Participants were 457 students in grades nine through 12 from four high schools near Phoenix, Arizona. Three questionnaires were administered: (1) a 65-item social attitude questionnaire on attitude variables including liberalism, authoritarianism, belief in a just world, and legal-social responsibility; (2) a 50-item criminal justice knowledge survey covering law, police, prisons, courts, and juvenile justice; and (3) self-reports of parental educational attainment and occupations and students' own expected level of educational attainment. Analysis of results showed that legal-social knowledge and attitudes are related, at least to a moderate degree. Low positive correlations were found between the knowledge measure and legal-social responsibility, educational expectations, socioeconomic status, and grade level. Significant sex differences appeared in attitudes of liberalism, legal-social responsibility, and authoritarianism. The authors suggest that a remaining research problem is the effect that attitudes of students entering law-related education programs have on knowledge acquisition. (AV)
