A lot of students go to a different place for graduate school, regardless. In fact at the public U I attended it was commonly said that it was harder to get accepted into graduate programs if you had attended undergrad there (schools like to diversify).</p>
<p>Counterpoint to dodgersmom, at a college without graduate programs, undergrads sometimes have more opportunity to work as graders and assistants to the faculty. At university those positions are more likely to go to the (graduate) teaching assistants.</p>
