Sometimes a treatment, such as receiving a high school diploma, is assigned to students if their scores on two inputs (e.g., math and English test scores) are above established cutoffs.

Descriptive evidence shows that English learners (ELs) have lower high school graduation and 4-year-college attendance rates than monolingual and fluent English users. Applying the regression discontinuity design to rich administrative data from a large district in California, this study identifies the first causal effects of initial EL…
