New school times in San Francisco

How did SFUSD select new start and end times for its 120+ public schools?

Selecting start and end times is hard, because the number of possibilities is very large, and because a good solution must meet the needs of students, teachers, staff, and families.

Spreading start and end times allows school districts like SFUSD to re-use buses efficiently and drive down transportation costs. But bus schedules are just one piece of the puzzle.

Mathematical analysis can support districts in this decision-making process. We built this website so you can peek under the hood and understand how algorithms can chart a path towards better policies.

Here on the right side is a map that illustrates the new start times.
