This monograph reports on the instrument development phase of the attitudinal section of the International Association for the Evaluation of Educational Achievement (IEA) Civic Education Study. During this development the general emphasis was on the measurement of a variety of dimensions derived either from statements of curricular objectives in the ten participating countries or from earlier political socialization studies which measured anti-authoritarianism, equality and civil liberties, feelings of efficacy, percepts of a good citizen, and perception of the community. The final instruments were the result of a four-year period of development, with the aid of comments from national educational research centers, from experts in civic education, and from a series of three pilot studies which are described in the monograph. Also included in the appendices are projective techniques for the measurement of children's civic attitudes and a copy of the final measurement instrument. (Author/DE)
