This paper addresses the ideal of citizenship in the US and how particular meanings of history, culture, and language are encoded in government policy and practice. The US government (Citizenship and Immigration Services) presents citizenship as a commitment to shared knowledge and values, and it requires applicants to possess competence in “ordinary English language.” However, a critical discourse analysis of the naturalization test material reveals a de facto policy of higher English proficiency than is claimed. Furthermore, the history and civics requirement of the citizenship test demands memorization of only certain historical facts deemed important. Citizenship policy analysis is paralleled by a localized ethnographic study of an adult ESL/citizenship class, where the instructor’s teaching perspectives and pedagogy reveal how a different set of citizenship meanings is understood and transmitted to the students than is officially promoted. The paper concludes by offering suggestions for citizenship curricular reform.
