Despite the essential position of introductory courses within most political science departments' curricula, comprehensive comparisons of introductory requirements for majors have been somewhat rare. In this manuscript, I report on the state of introductory requirements through analyses of data from 381 national liberal arts colleges and universities (164 colleges and 217 universities, respectively) that offer a major or its equivalent in political science. These data show that a great deal of curricula diversity exists across departments: While nearly 30% of departments require at least three distinct introductory subfield courses, another near 30% do not require any specific introductory courses. Despite this diversity, an introductory course in American politics represents the de facto standard introductory course within the discipline. In comparison, a general, cross-subfield introductory course in political science is required in a minority of the departments sampled. My analyses reveal that structural and curriculum-based variables, including the total number of courses required, whether or not a department grants PhDs, and faculty size, are correlated with a general introductory requirement.
