Some studies in both Massachusetts and New York City have found that a «No Excuses»
educational approach —
characterized by mandated intensive tutoring, longer instruction times, frequent teacher feedback, strict disciplinary policies, and high expectations for students — is a common feature among charter schools with the biggest positive effects (however, the most effective of these schools are located in the most
disadvantaged neighborhoods, making it difficult to disentangle whether this is due to the No Excuses approach or sub-par public school alternatives).
