From the students’ designer cell phones to the number of families paying full price even as tuition and fees climb past $40,000, it’s clear the most prestigious colleges are overwhelmingly attended by the wealthy.

It’s a problem colleges are speaking about more frankly and have tried to address with more financial aid, but with only mixed success. At the most selective schools, a 2003 study found, just 3 percent of students came from the poorest socio-economic quarter of families, while 74 percent came from the richest.

Now, a small group of selective colleges is turning its attention to what may be an untapped reservoir of able, low-income students: the 6.5 million people who attend community colleges. Historically, those students have been ignored by elite colleges, which recruit mostly at high schools and often accept few or no transfers because they want to offer a distinctive four-year experience.

Five well-known private colleges and three highly selective public schools – the flagship campuses of the Universities of Michigan, California and North Carolina – were to announce plans Monday to accommodate a total of about 1,100 more community college transfer students from low- to moderate-income families over the next four years.

The private colleges participating are Amherst, Mount Holyoke, Bucknell, Cornell and the University of Southern California.

Although the numbers amount to a relative handful – with Cal taking by far the most transfers – the hope is that the variety and prestige of the schools involved will persuade others to take a chance on students who have started at two-year schools for financial or family reasons.

“There’s a lot of focus at Harvard and lots of other places on the fact that there are no low-income students at those schools, or very few,” said Joshua Wyner, the Cooke Foundation’s vice president for programs. “The place where a lot of them are that nobody seems to be looking is community colleges.”
