This paper reports on the results of an ongoing large-scale nationally representative sample of college students, which provides time series data on attitudes for a broad array of issues. A representative sample of between 250,000 and 350,000 freshmen, entering more than 300 institutions throughout the nation, was surveyed each fall (1967-1974) by UCLA and the American Council on Education as part of the ongoing Cooperative Institutional Research Program (CIRP). The characterizations of students of the mid-1970's as growing more apathetic and as being more conservative than their predecessors of the 1960's gained little support from a comparative analysis over time. With respect to student's political self-identification, while there is a shift away from the liberal end of the spectrum, there is a parallel trend away from the conservative end as well over the six years, 1969 to 1974. The relatively high level of awareness and concern over current societal and collegiate issues among the most recent college entrants indicates that continuing strong support for reform is likely to emanate from the college community. In general, today's student body might be characterized as a more viable and effective locus for potential mobilization of social criticism and dissent possibly of more positive and constructive tone than that of the 1960's--than at any earlier time in history.
