For too many districts, the answer would be "a long time." Without being able to directly track buses on their routes, they're left with little way of overseeing bus's progress aside from relying on radio reports.
And if the bus driver is unable -or unwilling- to radio in, they're basically in the dark.
Fortunately, there is an alternative. School bus tracking systems, based on a GPS unit which is constantly reporting the bus's location, are a robust and easily-implemented technology. They are still somewhat expensive to roll out, but they bring major long-term benefits which easily justify the expense.
Why leave anything about your buses to chance? With GPS tracking systems in place, tied to a map of the area, you'll always know exactly where your buses are - within a few feet! Better yet, you can set up alerts that will let you know if the bus stops unnecessarily, deviates from its route, or otherwise shows worrisome behavior.
When you know where your buses are with precision, that means you can also quickly dispatch help when it's needed. Having precise location data, and instant alerts if something is wrong, potentially means lives being saved.
The data from the GPS unit can be streamed to your home office, or to a smartphone app, or to almost anywhere else you want. You could potentially even give parents the ability to directly check on their child's location for themselves. That cuts down on calls to the office!
Another major benefit to bus tracking is that your performance data gains extra depth, with extra-precise mileage calculations, braking distance data, and other useful diagnostic information. This makes bus maintenance easier, as well as giving you more options for performance optimizations like reducing fuel use.
Sure, your drivers are supposed to be stopping for every stop sign and railroad crossing - but are they really? With school bus tracking systems, you will be able to monitor their driving habits and make sure they're always driving legally.
In short, school bus tracking systems can quickly pay for themselves in terms of their overall benefits, especially in terms of optimization and preventing driver misbehavior.
