Greece is denying thousands of asylum-seeking children their right to an education because of a European Union-backed migration policy that traps them on the Aegean islands.

Human Rights Watch found that fewer than 15 percent of more than 3,000 school-age asylum-seeking children on the islands were enrolled in public school at the end of the 2017-2018 school year and that in government-run camps on the islands, only about 100 children, all preschoolers, had access to formal education. The asylum-seeking children on the islands are denied the educational opportunities they would have on the mainland. Most of those who were able to go to school had been allowed to leave the government-run camps for housing run by local authorities and volunteers.
