"Culture shock" is the way some veterans describe their transition from military life to college life on campus. Most don't feel they fit it in. And often, institutions don't make it any easier. That's what researchers with the National Survey of Student Engagement found after interviewing 11,000 veterans attending four-year schools.

Compared to regular students, most veterans seldom interact with instructors. They're less likely to sign up for internships or study-abroad programs. And one in five has a disability. Veterans say schools don't offer them support services that might help them better connect with campus life, socially or academically.

Veterans are also more likely to transfer or enroll part-time, because they're often juggling work and family. Researchers say college officials are not doing nearly enough to help veterans succeed.
