A report is presented of a national assessment of young Americans' achievement of citizenship goals. Conducted by the National Assessment of Educational Progress, the study measured achievement of six behavioral objectives. These were: (1) show concern for the well-being and dignity of others, (2) support just law and the rights of all individuals, (3) know the main structure and functions of government, (4) participate in democratic civic improvement, (5) understand important world, national, and local civic problems, and (6) approach civic decisions rationally. Students in the survey represented nine-, 13-, and 17-year-old age groups. Chapter one of the report is a summary of citizenship achievement at each age for all six objectives. Chapters two through seven each focus on one of the objectives, discussing overall results for that particular objective and featuring sample questions. The final chapter compares different performance levels among age groups. Tables of data accompany the discussion in all chapters.
