From Education Week: As teachers rock babies in their arms, a sense of calm settles over a classroom in a bright, modern building on a side street in the northeastern quadrant of Washington, D.C., in one of its poorest neighborhoods. Here at Educare, a $16 million early-childhood school that opened in July with the goal of closing the achievement gap for local children living in poverty, building that sense of security and familiarity is a major component of the program. These infants will spend three years with the same teachers. At age 3, they’ll move to a new teacher who will stay with them for two more years.
