Enrollment in higher education has risen dramatically in Latin America, especially in Chile. Yet graduation and persistence rates remain low. One way to improve graduation and persistence is to use data and analytics to identify students at risk of dropout, target interventions, and evaluate interventions’ effectiveness at improving student success. We illustrate the potential of this approach using data from eight Chilean universities. Results show that data available at matriculation are only weakly predictive of persistence, while prediction improves dramatically once data on university grades become available. Some predictors of persistence are under policy control. Financial aid predicts higher persistence, and being denied a first-choice major predicts lower persistence. Student success programs are ineffective at some universities; they are more effective at others, but when effective they often fail to target the highest risk students. Universities should use data regularly and systematically to identify high-risk students, target them with interventions, and evaluate those interventions’ effectiveness.

Debates in education policy draw on different theories about how to raise children’s achievement. The school competition theory holds that achievement rises when families can choose among competing schools. The school resource theory holds that achievement rises with school spending and resources that spending can buy. The family resources theory holds that children’s achievement rises with parental education and income. We test all three theories in Chile between 2002 and 2013, when reading and math scores rose by 0.2-0.3 standard deviations, while school competition, school resources, and family resources all increased. In a difference in differences analysis, we ask which Chilean municipalities saw the greatest increases in test scores. Test scores did not rise faster in municipalities with greater increases in competition, but did rise faster in municipalities with greater increases in school resources (teachers per student) and especially family resources (parental education, not income). Student grade point averages show similar patterns. Results contradict the school competition theory but fit the family resource theory and, to a lesser extent, the school resource theory.
