Over the past fifty years, fifty percent of students who enter colleges do not finish their four-year degree, because a substantial number of them are not prepared for college. Universities are employing innovative approaches and pedagogies aimed at accelerating the learning process and academic ability of freshman students. One popular approach is summer bridge programs(SBPs) that provide foundational knowledge for core college courses and a roadmap for successful college life. Typically, the bridge programs happen during the summer before a student's first year and are considered a bridge from high school to college. This paper reviews recent summer bridge programs at diverse teaching institutes, private, public, and open access educational institutes.
