From New York Times:

Over the course of the last school year, The New York Times followed the paths of three residents of the Aspire Public Schools, a charter system with schools in California and Memphis that has a lengthy and intense mentorship process. Focusing on apprenticeships and time spent in the classroom rather than more theory-based teacher training, the Aspire model is one of a number of such programs emerging across the country. The United States Department of Education is focusing more on the quality of teacher preparation programs and has designated $35 million in grants this year to help colleges and school districts develop new teacher training, prioritizing residencies like Aspire’s.
