“No Excuses” charter schools are at the center of many debates in education policy. First, what accounts for their test success, excellent learning environments or merely test preparation? Second, are strict behavior policies necessary to create efficient learning environments or are they harmful to students and their ability to navigate authority? This study uses classroom observations, student surveys, and interviews of administrators, teachers and students to understand the dynamics of pedagogy and discipline in two high-performing charter schools in New York City. Surprisingly, what makes these top “no excuses” schools successful is what distances them from the “no excuses” standard definitions. The schools displayed progressive mathematics pedagogy, reflective and abridged discipline practices, and strong school cultures that retained both students and teachers. These findings suggest that there are more nuances in the “no excuses” model than previously known and which need to be understood before continued replication.
