Citizenship is one of 10 subject areas selected for assessment of specific performance outcomes under the National Assessment Program. The Citizenship objectives are: 1) concern for the well-being of others, 2) support for individual rights and freedoms, 3) recognition of the value of just law; 4) knowledge of the main structure and functions of government, 5) participation in civic action, 6) understanding of the problems of international relations, 7) rational civic decision-making, 8) acceptance of the responsibility of self-development, and, 9) help and respect for the family. Some 90,000 subjects in four age groups (9, 13, 17, and 26-35 year olds) were tested in 2,500 schools or in their homes. Adequate representation was sought of: four national sections, urban and rural communities, major ethnic groups, both sexes, and varied economic and occupational backgrounds. The procedures followed this general pattern: 1) the development of objectives, 2) development, tryout, and revision of measurement instruments, 3) testing of the national sample, and 4) scoring, analysis, and reporting. One general result was evident: progress on most objectives from 9 to 17 years of age. The report includes the results (by age group) and the measurement instruments. Comparative results will appear in later reports. Related documents are ED 043 098 and SO 000 898.
