The Three Tier program was implemented to help make student transportation more efficient and cost effective by coordinating the start times of schools. By coordinating the start times a single bus can run three separate routes—one each for the elementary, middle, and high school to which it delivers students—instead of having three buses run one route each.
The start and end times are as follows:
7:45 AM–2:15 PM
8:00 AM–2:30 PM
8:50 AM–3:55 PM
8:10 AM–3:10 PM
