This guide was created to help district leaders understand the benefits and drawbacks of the four-day school week, assess their district's readiness to make the switch, and evaluate the results of implementing the new schedule. This guide begins with an overview of common goals and outcomes for the four-day school week. It then provides a set of questions and tools that helps district leaders assess their district's readiness to implement the schedule change, along with guidance to assess the results. This guide's goal is to help district and community leaders make informed decisions about the usefulness of the four-day school week and, if they decide to move forward, implement the schedule in the most effective way possible.
