This document discusses barriers to achieving universal primary education as outlined in the UN's Goal 2. The key barriers identified are humanitarian emergencies/conflict which displace millions of children from school, gender discrimination that prevents girls' education, and child labor pulling children from schooling. The document argues that education is needed to overcome these barriers by fighting conflict, discrimination, and labor. Progress is noted in increasing enrollment rates and reducing the number of out-of-school children from 100 million in 2000 to 57 million in 2015, though more work remains.
