Americans pay the highest price for dropping out of school compared to other dropouts around the world.
Adults who don't finish high school in the United States earn 65 percent of what people who have high school degrees make. No other country has such a significant income gap.
Adults without a high school diploma typically make about 80 percent of the salaries earned by high school graduates in nations across Asia and Europe. Countries such as Finland, Belgium, Germany and Sweden have the smallest gaps in earnings between dropouts and graduates.
The figures come from a study by the Paris-based Organization for Economic Cooperation and Development. The report aims to help leaders see how their nations stack up.
About one-third of students in the United States don't finish high school on time -- or at all.
