From a professor's perspective, students in their mid twenties and older bring several valuable qualities into the classroom which their younger classmates often do not share. First, they're in the class because they want the education, not just because "everyone else went to college." Older students recognize the value of the experience. Second, they're more reliable. They attend class unless they have a serious problem, they turn in assignments on time, they pay attention, and they are serious about doing the work well. Finally, they're more thoughtful and analytical. Their life experiences come into play, and they don't simply spout what they've "heard," but actually think about the course material, consider alternatives, and write interesting papers with detailed reflection and analysis. Who wouldn't want a student like that?
