The purpose of this research was to explore student endorsement of an environmental worldview during the college years through a sampling of freshmen and seniors. Nine independent samples of freshman and senior class undergraduates (N = 779) were surveyed over a five year period in a small, independent liberal arts college. The survey instrument included the New Ecological Paradigm (NEP) scale, demographic items, and other measures, such as knowledge of, and worry over, climate change, and perceived priority for environmental issues. In general, NEP endorsement was weakly pro-environmental and was higher among women. Endorsement was stable during the years of the study, except for a temporary, significantly lower level during the recession. Class status had no effect on either NEP endorsement or responses to two questions assessing knowledge of global warming. Knowledge of climate change was comparable to that shown in samples of the public taken by other researchers.
