Ramp-Up to Readiness™ (Ramp-Up) is a college readiness program that aims to enhance five dimensions of readiness in high school students: academic, admissions, career, financial, and personal-social. Ramp-Up's developer theorizes that increasing these dimensions of readiness in high school students will improve college enrollment and success rates. Implementation of Ramp-Up involves distribution of program leadership responsibilities across multiple staff, off-site and on-site professional development for key staff, advisories, and guidance in postsecondary planning for all students. Because elements of implementation require changes in staff roles and attitudes within high schools, school and district administrators seek evidence that schools are able to adequately implement Ramp-Up. This study addressed the implementation question by collecting data from 10 high schools that implemented Ramp-Up in 2013/14 and 10 similar high schools that did not implement the program that year.
