The overall graduation rate for black male students in New York City was 58 percent in 2014 - student retention rates are equally poor. But one school achieved a 100% on-time graduation rate last year, motivating their students with a student-founded, student-sustained 'fraternity'.

Attending college is not always a given option for gifted teenagers from less-than-wealthy backgrounds. National organization QuestBridge creates a way for low-income and minority high-achieving students to go to their dream colleges free of cost.

Lack of reading material is not only a third-world problem – many poor families in the United States lack access to and funds for books. A program that helps get books to into the homes of low-income families can boost literacy, and help publishers, too.

How can rural African children learn to read when there are no books in their languages? Save the Children helps kids to create their own books, creating a homemade library for their village.

Students are grouped into small, personalized cohorts so they can be both mentors and mentees for their fellow peers, creating a collaborative learning space for all.

Teaching reading skills to children early is crucial, especially with respect to their educational success later in life. School systems are switching reading programs to help underachieving students have one on one time with a tutor.
