Even students who only take one IB class and sit for one exam are still closing the gap.
“The best treatment is do to the whole diploma and take all the exams,” Young said. “That’s the gold standard. But it turns out, if you can’t do that, and you just participate in one course, that’s sufficient to boost long-term educational outcomes.”
Young not only found elevated high school graduation and college-going rates, but also that low-income students persisted in college through at least the first year at the same rate as their wealthier peers. Future studies will continue to track these students.
