The Political Science Department offers undergraduate majors leading to B.A. degrees in Political Science, Political Science/ Administrative Studies, Political Science/ International Affairs, Political Science/Law and Society, and Political Science/Public Service.

Political Science Major

The major requirements for the B.A. degree in Political Science are as follows:

• 1. Lower-division requirements (four courses [at

least 20 units]): one course from a, b, c, and d.

Students in the major must complete two of the four lower-division Political Science courses with a grade of “C” or better in order to take upper-division Political Science courses.

• a) POSC 005 or POSC 005H or POSC 005W

or POSC 007

• b) POSC 010 or POSC 010H or POSC 010W

• c) POSC 015 or POSC 015H or POSC 017

• d) POSC 020 or POSC 020H

Upper-division requirements (nine courses [at least 40 units])

• a) One course from each of the following

areas:

• (1) U.S. Government and Politics: POSC 100, POSC 101, POSC 104 or 104S,

POSC 108, POSC 143, POSC 144 or POSC 144S, POSC 145, POSC 146, POSC 148 or POSC 148H or POSC 148S, POSC 149, POSC 166, POSC 167, POSC 168, POSC 170, POSC 171, POSC 172/URST 172, POSC 173 or POSC 173S, POSC 180 or POSC 180S, POSC 181, POSC 182, POSC 183, POSC 184 or POSC 184S, POSC 186

• (2) Comparative Government and Politics:

POSC 120, POSC 131, POSC 133, POSC 151, POSC 152, POSC 153, POSC 154, POSC 155 or POSC 155S, POSC 156, POSC 157, POSC 158/ LNST 148, POSC 159 or POSC 159S, POSC 160 or POSC 160S, POSC 161/ LNST 188, POSC 162/LNST 142 or POSC 162S/LNST 142S, POSC 163 or POSC 163S, POSC 164 or POSC 164S, POSC 165 or POSC 165S, POSC 178 or POSC 178S, POSC 188 or POSC 188S The study of political science provides undergraduates with career opportunities in law, government service, education, journalism, and business. Because career goals may vary, the department offers two distinct majors. For students planning careers in such areas as law, journalism, or teaching, the traditional major in Political Science is appropriate. For students considering careers in government service, especially for such positions as program and budget analyst, urban planner, and executive or administrative assistant, the appropriate major is the Political Science/Public Service major.

Further information on the study of law or the legal profession may be obtained from the departmental prelaw counselor.

Political Science/Administrative Studies Major

The Political Science/Administrative Studies major combines the disciplinary interests of political science with a particular focus on administrative behavior, tools of decision making, and politics of public policy. The Administrative Studies component provides an interdisciplinary approach to training in administrative analytical skills and, more importantly, to the study of the policies, politics, and theories of public administration. The Business Administration courses provide a variety of perspectives on these objectives. In addition, they should be of particular value to those planning to either enter directly into public administration (federal, state, or local levels) or attend a professional school of administration.

Political Science/International Affairs Major

The Political Science/International Affairs major offers a challenging opportunity to observe and participate in the dynamics of global interaction. As versatile as it is valuable, a degree in international affairs prepares the student for work in many diverse careers in the private sector, government, and academia. From diplomatic missions to the United Nations to intense debate with a private “think tank,” careers in international affairs should appeal to students seeking to understand and influence the world in which we live.

Political Science/Law and Society Major

The Law and Society major is open to undergraduate students with junior standing who have completed LWSO 100 with a grade of “C” or higher. The major combines the breadth of a political science major with a particular focus on the theme of law and law-like relationships. The major provides a multidisciplinary approach to the study of legal and law-like institutions and relationships and focuses on relationships that have formed the core of political science: the emergence and development of law, the relationship between law and values, and the growth of the power of the state, among others. The courses provide a variety of perspectives on this theme, and the range of courses should be of particular benefit to those who plan to attend law school.
