The Lee County School Board proposed a plan to address its bus driver shortage by adjusting school start and end times. If approved, the new schedule would begin in August, when the new school year begins. The proposal would reduce the current bus system from four tiers to three, allowing bus drivers more time between routes. The first tier would include 471 bus routes, the second tier 404 routes and the third tier 300 routes. This change would affect school start and end times throughout the district. School start times could be as early as 7:30 a.m., with end times as late as 4:20 p.m., WINK News reports.
