Welcome to The National Center on Time & Learning’s Database of Expanded-Time Schools
The National Center on Time & Learning has compiled this unique database of U.S. public schools that operate with more time per day and/or more days per year, compared to surrounding public schools, for all enrolled students. In many states, public schools are subject to multiple time-related requirements. However, the thresholds set for both school day and school year length vary significantly among states. As a result, schools in the database are compared against other schools in their same area. Starting in the 2011-2012 school year, schools with at least 30 minutes more time per day and/or 10 more days per year are considered expanded-time for the purpose of this resource.

Features of the database include:
- Basic information about each school (2010-2011, 2011-2012) and school schedule information (2010-2011, 2011-2012), collected by NCTL staff.
- Demographic data (2008-2009, 2009-2010), drawn from the U.S. Department of Education's Common Core of Data.
- State assessment data (2006-2007, 2007-2008, 2008-2009, 2009-2010), obtained from the individual states' Department of Education websites.
- A subset of schools also has completed an online survey, which includes detailed information related to student and staff time practices, program offerings, and financing.
Administrators can add to or amend their school's data by clicking on the link that appears on each individual school’s profile page.
