If the school bus has seats available for additional students after a determination of actual ridership has been made, then students living close to the eligibility boundary line (1 mile or 1 ½ mile – See Ridership) could be eligible for bussing. Additional stops are not added to the route to accommodate space available seating and space available seating may be temporary if additional bussing eligible riders present themselves in the future. “Space Available” seating is not available until after the fourth week of school.
