This study considered whether participation in several out-of-class experiences during high school influenced the odds that a student will aspire to earn at least a Bachelor's degree. Additionally, this study considered whether these experiences, considered together, had a cumulative effect on the odds that a student will aspire to earn at least a Bachelor's degree, and whether the influence of these high school experiences on college aspirations was moderated by a student's race/ethnicity or socioeconomic status. Results of the study revealed that several high school experiences, including participation in science-related school programs, participation in extracurricular activities, sitting in on or taking a college class, searching the Internet or reading college guides for college options, and talking to a school counselor about going to college, increased the odds that a student would aspire to earn at least a Bachelor's degree. Additionally, results revealed that participation in four or more of the high school experiences examined in this study had a cumulative, positive influence on students' eleventh grade college aspirations, and that the relationship between participation in these high school experiences and students' aspirations to earn at least a Bachelor's degree was not moderated by race/ethnicity or socioeconomic status.
