A new study by the National Center on Time and Learning (NCTL) shows that the number of schools with expanded learning time has increased from 655 in 2009 to 1,002 today, a 53 percent increase. The study, Mapping the Field: A Report on Expanded Time Schools in America, says these schools generally emphasized longer school days rather than an extended year. The study was released as NCTL, the Ford Foundation, and education officials announced a new collaborative "to develop high-quality and sustainable models of expanded learning time in over 40 schools across five states (Colorado, Connecticut, Massachusetts, New York, and Tennessee)."
