<p>Based on analysis of a huge number of research studies from the 1970s through 2002, comparing entering freshmen to graduates:</p>
<ul>
<li><p>Students make statistically significant freshman- to senior-year gains on a variety of dimensions of learning and cognition.</p></li>
<li><p>Students gain during the college years in their academic and social self-concepts and overall self-esteem
Gains in students sense of independence and control over their lives and academic fortunes and in their interpersonal competence and leadership skills appear to accompany gains in self-concept and self-esteem.</p></li>
<li><p>The proportion of students who placed a high value on the intrinsic rewards of education grew by about 20 to 30 percentage points, and students came to attach a lower value to the extrinsic value of employment.</p></li>
<li><p>[In 1991] The research indicated a general shift among college students toward the liberal end of the sociopolitical continuum, with students becoming less doctrinaire in their religious values over time and more likely to support gender equality and to be tolerant of the political, social and religious views of others.
[In 2005] The degree of liberalization in student views reported since 1990
was more limited than that of the preceding decades. The percentage of students on the far left or far right remained virtually unchanged from first to senior year, with shifts of about 4 percent both to the left and the right coming largely from middle-of-the-roaders.</p></li>
<li><p>Undergraduates increase significantly in their use of principled reasoning to judge moral issues.
The main change taking place during the undergraduate years is from using moral reasoning that concedes to societal authority
to using reasoning based on the application of universal moral principles.</p></li>
<li><p>Evidence also suggests that postsecondary educations influences extend beyond the individuals who attend college to the nature of their childrens lives</p></li>
