Ideally, nonexperimental methods that aim to replicate the results of rigorous randomized experiments focus on the intent to treat (ITT) experimental impact estimate, the most causally rigorous measure. This working paper develops a new replication approach that facilitates testing...

A new analysis from the National Study of Charter Management (CMO) Effectiveness provides the first systematic evidence available on the effects of CMOs on the critical long-term outcomes of high school graduation and college entry. The study shows that some—but not all—CMOs...

A new longitudinal national study of the practices and effectiveness of charter-school management organizations (CMOs) reveals a wide range of organizational models and educational strategies, with achievement effects that are more often positive than negative but vary substantially among CMOs....
