How do you take students performing in the bottom 25 percent of their class to walking across the stage at college graduation? The Baltimore non-profit Thread seems to have the answer: follow each student for a decade, provide them with a team of supporters, and do whatever it takes to help kids succeed, from packing lunches to matching students with summer internships. Ninety-two percent of Thread students graduate from high school, and 90 percent are accepted to college. Sarah Hemminger, co-founder of Thread, tells us how Thread is scaling up its efforts. And we hear from a volunteer and from a member of Thread’s first cohort, now a board member with the organization.
