"Bottom Line" provides intensive advising for low-income high school students, most of whom are the first in their family to go to college. The advising is designed to help students apply for college and financial aid and select a high-quality, affordable institution. For students who attend one of "Bottom Line's" target colleges which they identified as providing a high-quality education at an affordable price, "Bottom Line" continues to provide regular support to students on campus for up to six years. This What Works Clearinghouse (WWC) report, part of the WWC's Transition to College topic area, explores the effects of "Bottom Line" on enrolling and progressing in college. The WWC identified two studies of "Bottom Line," one of which meets WWC standards. The evidence presented in this report is from one study of the impact of "Bottom Line" on high school and college students--including African-American, Hispanic, and Asian students--based in Boston, New York City, and Worcester, Massachusetts.
